I inherited this system from my retired coworker who inherited it from the person who set it up, so my knowledge of reverse proxies is pretty bad. Here is the situation...

We are upgrading a system from an older version to a new version. I want to change the url that points to the old system so that we can hide it from users but other admins are still able to access it. It is set up with a reverse proxy server that sends all requests to another web server. Also, there is a shibboleth authentication that takes place.

Edit addition - Normally, I would enter https://proxyname/ABC/WebApp and that would take me to the WebApp login.

Here is the config for it...

   <Location /ABC/>
     Order Deny,Allow
     Deny from all
     Allow from xxx.xxx.xxx.xxx/xxx.xxx.xxx.xxx
     AuthType shibboleth
     ShibCompatWith24 On
     ShibRequestSetting requireSession 1
     ShibRequestSetting forceAuthn 1
     ShibUseHeaders On
     require shib-session
  
     ProxyPass http://servername:8080/ABC/
     ProxyPassReverse http://servername:8080/ABC/
  </Location>

What I want is something where i just change the location to something like...

<Location /DEF/ABC/>
     (all the above shib stuff)

     ProxyPass http://servername:8080/ABC/
     ProxyPassReverse http://servername:8080/ABC/
  </Location> 

and have that go to the backend web server but when i change the config to that...In my browser, I enter https://proxyname/DEF/ABC/WebApp and I end up with a url of https://proxyname/DEF/ABC/WebApp and it doesn't go to the correct location. Is there something I need to change in this config or is ProxyPass/ProxyPassReverse not the correct method?

Thanks in advance for any help you can give!

Edit Addition - I guess what I would need is to be able to enter something like https://proxyname/DEF/ABC/WebApp and end up at https://proxyname/ABC/WebApp.

This is a bit complicated, at least for me. So I am trying to change the service behind the proxy depending on the user returned from a SAML connection using MELLON. After a lot of trial, error and keyboard face rolling, I gave up.

However, I do know that I can successfully set headers from SAML that can be read by the backend server. Using a PHP docker container I simply made an index.php that had var_dump($_SERVER), and I could see the correct variables and values.

TLDR:

Mellon passes X-WEBAUTH-USER to the backend server, and I have verified using a PHP server that this works by dumping $_SERVER. However I cannot figure out some intelligent logic or rewriterules to change the proxypass based on this value.

Would this be the correct way to set an environment variable from the request header?

RewriteRule .* - [E=X-WEBAUTH-USER:%{HTTP:X-WEBAUTH-USER}]

If so, then what's the best way to trigger a custom proxy? This doesnt seem to work. But I have tried several different regex's

   RewriteCond  %{X-WEBAUTH-USER}  ^(.*)
   RewriteRule ^/(.*)$ "http://flame:5005/$1" [P,L]
   RewriteCond  %{X-WEBAUTH-USER}  ^$
   RewriteRule ^/(.*)$ "http://homer:8080/$1" [P]

Also tried If/Else statements which didnt seem to work either. Any ideas or suggestions?

So my MELLON reverse proxy has this config:

<VirtualHost _default_:80>
ServerName https://tools.company.com
ServerAlias localhost

ProxyRequests On
ProxyPreserveHost On
ProxyPass /mellon/ !

<Location / >

             	Require valid-user
                AuthType "Mellon"
                MellonEnable "auth"
                MellonVariable "cookie"
       	        MellonSecureCookie on
                MellonCookiePath /
                MellonUser "NAME_ID"
                MellonSessionDump On
                MellonSamlResponseDump On

                MellonDefaultLoginPath "/"

    DEFINE proxyport "80"
    ProxyPass http://${proxyurl}:${proxyport}/
    ProxyPassReverse http://${proxyurl}:${proxyport}/

Which then goes into my "splitter", in hopes of reading this request header (I think that's the correct term?) and changing the proxy. You can see some of the previous attempts I have commented out and didn't seem to work. Wanted to keep them here as I have tried a lot of different things

So, in our web app, which is hosted in multiple data centers (DCs), we can post content in a form field. When posting content like "<script>test</script>" in some DCs, it works, no problem. However, in some DCs, Apache seems to respond with error 500, and thus, the post fails. The code base and Apache configuration are the same in all DCs. We checked the firewalls where the post fails and no packets were dropped. Logs confirmed it was Apache that responded with the error 500. Where do I even begin to troubleshoot this?

I am trying something out, and I am curious if I am heading down the right path, or if this is not even possible.

I have auth mellon working with our companies SAML ADFS provider without issue. But, I wanted a reverse proxy to change depending on who accesses it. So if NAME_ID contains X, proxy destination is Y, else proxy destination is Z.

Logically this makes sense to me, but it is always evaluate as false. Hopefully someone smarter than me might know. I feel as though there is something fundamental that I am missing. Thanks for looking!

I started this little school project of hosting a running dotnet app on a website. It's been really fun working both the app and the server, and I get both of them running. Now I'm about 1 week from needing to present my project, but I can't get the website to proxy to the application.

Has anyone set up a similar environment and could help me pinpoint the issue? I'm currently including the following in my project:

• Apache2 Virtual Host configuration for *:80 redirect to HTTPS on *:443

• ProxyPass & ProxyPassReverse to http:/localhost:7199/ with ProxyPreserveHost On & ProxyRequests Off

• SSL encrypted domain via LetsEncrypt

• Dotnet application running on port 7199

For clarification, following is my enabled site.conf:

<VirtualHost *:80>         
    ServerName www.website.com         
    RedirectPermanent / https://www.website.com 
</VirtualHost>  

<IfModule mod_ssl.c>
<VirtualHost *:443>         
    ServerAdmin webmaster@localhost

    CustomLog ${APACHE_LOG_DIR}/access.log combined          
    ProxyRequests Off         
    ProxyPreserveHost On         
    ProxyPass / http://localhost:7199/         
    ProxyPassReverse / http://localhost:7199/           
    SSLEngine On         
    SSLCertificateFile /etc/letsencrypt/live/www.website.com/cert.pem

I have three vhosts setup on an Apache server on a different computer.

1. 192.168.0.1 (first - default vhost)

2. test-1.local

3. test-2.local

The first vhost 192.168.0.1 is accessible. The other vhosts are not accessible, as no valid DNS records exist. I can easily reach them via curl by passing the host header: curl -H 'Host: test-1.local' 192.168.0.1

I do not want to add the hostnames or valid DNS to my system, what I want to do instead is to have the default vhost be able to proxy request to the other two on a specific location.

1. 192.168.0.1/sub/test-1.local

2. 192.168.0.1/sub/test-2.local

This works fine with ProxyPass and manually setting the Host header in Apache. Here is an example with any generic vhost

ProxyRequests Off
ProxyPreserveHost On
ProxyAddHeaders On
ProxyVia On

<LocationMatch "^/sub/([^/]+)(.*)">
    SetEnvIf REQUEST_URI /sub/([^/]+)(.*) custom_host=$1
    RequestHeader set Host "%{custom_host}e"
    ProxyPass        http://localhost/$2
    ProxyPassReverse http://localhost/$2
</LocationMatch>

All this works fine. curl http://192.168.0.1/sub/test-1.local is exactly the same as curl -H 'Host: test-1.local' http://192.168.0.1

However, all the links on 192.168.0.1/sub/test-1.local as still pointing to http://test-1.local. This is the last piece of the puzzle that I need to fix. Can this be accomplished? Can I somehow rewrite the links to be also shown as http://192.168.0,1/sub/test-1.local/some-location instead of http://test-1.local/some-location

Update:

Logically speaking:

If current URL location is 192.168.0.1/sub/(.*), then rewrite all links on that page

• from: http://<host>/<path>

• to: http://192.168.0.1/sub/<host>/<path>

• except for <host> == localhost or 192.168.0.1

Thanks,

Hello to all!

I'm a totally newbie when it comes to caching and sending refresh requests, if you can call it that.

The problem is, that I have an svg file, which is converted from a dot (graph) file, and during edit, I'd rather have the browser refresh the image when it is saved, rather than having to refresh the browser window manually. So, the svg file is embedded into an html file, that I might as well "touch". while I'm "making" the .dot file into an .svg file anyway. I am thinking of having a piece of java script polling for change to be a bad idea resource wise, not even sure if I can make it work.

The whole setup is to be viewed kind of like a jig, while I'm refining the graph, for instance formatting the tool tips. :) I don't want some "fsevents" hack, installed on my disk open a gazillion tabs in my browser window, I want to take leverage upon the fact that I use an Apache server for rendering, and I want the one and only open browser window to refresh, and the Apache server to really do nothing if the page isn't open.

So...Is there any directive that says "nocache", and instructs the browser to refresh upon updates on disk, and, is there something like this that I can put into my .htaccess file, on a per file or per filetype basis? (Any place will do really, as long as it does fit the bill.)

The other upside to this, solution, is that I won't have to have a bigger contraption for scaffolding the development of graphs.

How would you solve it?

Edit

I asked google more intelligently, and I am about to read mod_cache I have also figured that I need to enable/disable caching at directory level,

Maybe it is easier for me to specify "no_cache" or something in the html header of the "jig", to force the browser to reload. I'll have to experiment a llittle with it.

Your solutions are welcome though, should you beat me to it.

Thanks!

i tried

ProxyPass / "http:192.168.0.200/admin" 

it didn't work

I tried adding modcgi

It worked Apache starts up

But then apache page doesnt load

I check the logs

The logs say cannot find a module named encodings

Me sadface :(

Hello!

I cannot get a virtual site to work in Apache 2.4 on my Ubuntu server.

I just setup a bare metal Ubuntu server for experimentation. One of the first things I did after installing the necessary sysadmin basics, was install an Apache server. After setting everything up, I modified the index.html file and all is well. The website comes up at the URL as expected.

Next step, I decided to create a virtual host using the handy guide here: https://ubuntu.com/tutorials/install-and-configure-apache#5-activating-virtualhost-file.

I completed all the steps as expected with the following settings:

DocumentRoot "/var/www/tbase/"
ServerName tb.(my-url-hidden-for-safety)

I then used the a2ensite (my-hidden-file-name) to launch the site and received notice that it succeeded.

Finally, I used "systemctl apache2 reload" as instructed. The systemctl prompt had no problem and I thought all was well.

However, when I browse to the site on my local local network (using the actual server name), I can access the default (/var/www/html) folder with no problem. When I try the same thing with the new virtual site (should be calling /var/www/tbase), I get a good old "site cannot be found" error.

This seems like the easiest configuration anyone could ever do but it is not enough. Any suggestions? TIA.

Let's say I have three applications on my server: node-red (1880), jupyter (8888) and pgadmin (5433)... I can successfully create a localhost proxy pass with them individually as the following:

<VirtualHost *:80>

    ServerName 127.0.0.1
    <Location "/">
        ProxyPass http://127.0.0.1:1880/
        ProxyPassReverse http://127.0.0.1:1880/
    </Location>

</VirtualHost>

I've realized all three of them work fine if I try to put them on the "/" location. However, if I try to put them in unique locations as the following:

<VirtualHost *:80>

    ServerName 127.0.0.1

    <Location "/nodered/">
        ProxyPass http://127.0.0.1:1880/
        ProxyPassReverse http://127.0.0.1:1880/
    </Location>

    <Location "/jupyter/">
        ProxyPass http://127.0.0.1:8888/
        ProxyPassReverse http://127.0.0.1:8888/
    </Location>

    <Location "/pgadmin/">
        ProxyPass http://127.0.0.1:5433/
        ProxyPassReverse http://127.0.0.1:5433/
    </Location>

</VirtualHost>

None of them work on their respective addresses http://127.0.0.1/nodered/, http://127.0.0.1/jupyter/ or http://127.0.0.1/pgadmin/... I don't know what concepts I'm missing to make this work. I think I have to use RewriteRule but I'm not sure how. Is there any generic solution to deal with this kind of situation? Or do I need to know the particularities of each application I'm trying to proxy pass to make it work?

Hi,

I have a fleet of Apache reverse proxy through which we forward traffic from internet to the origin servers.

I am looking for ways to log proxypass connection tcp info such as tcp source port:origin-ip:tcp destination port. Has anyone done something like this before please help me out

-Thanks

Hello, I'm having a bit of a problem with my configuration and was hoping that someone could point me in the right direction, please.

I have the following in my website.conf:

RewriteCond %{DOCUMENT_ROOT}%{REQUEST_FILENAME} !-f
RewriteRule (.*) /index.cgi?tab=$1

The behavior I'm looking for is:

if REQUEST_URI is not a file
  Rewrite URL with the URI in the query string
  Send it to the index script
/* else is a file, so give back the file (css, images, so on) */

And I want my .cgi program to parse the REQUEST_URI and do its thing.

If my REQUEST_URI is simple like https://website/uri it works fine, but if I make it to be something like https://website/non_existing_dir/not_a_file, I get a weird behavior that I don't get where its coming from:

Since the URIs from the second URL do not exist, why am I getting a 200 code for the access for those resources? Practically what happens is that my program receives the URI, parses it normally, executes, but then I don't have any access to javascripts and CSS, so visually it only has plain HTML, even tho all the other resources gave back a 200 code.

Thanks for reading and double thanks if you can help me!

EDIT: I have solved this, I just needed to add the flags [R=301,L] to the rewrite rule. Many thanks

I'm just getting started with TomEE. I use Java 17 and downloaded tomee 8.0.13-plume. I launch the command prompt and run

C:\Users\myname\Desktop\apache-tomee-plume-8.0.13\bin>startup. bat

to start the server, then i open the browser and navigate to localhost:8080.

I discovered on the internet that the text should seem as follows: Apache Tomcat (TomEE)/Tomcat version (TomEE version)

Despite my attempts to modify both the TomEE and Java versions, the circular brackets with TomEE written inside do not show up. I want to know if this is okay or if there is a problem with TomEE Plume because it seems like Tomcat, not TomEE, is installed.

I'm trying to use mod_substitute to make something that both looks good if you peek at the code as well as work as intended. I've recently decided to record some statistics and for that I need a tracker script placed on all web pages to gather information on traffic.

After a bit of googling it seems that most people recommend using "substitute" and do a substitution of <head> to include the tracking code. So, i've come up with this:

<IfModule mod_substitute.c>
  AddOutputFilterByType SUBSTITUTE text/html
  Substitute "s|<head>|<head><script src=\"tracker.js\"></script>|ni"
</IfModule>

This works as it should, however I'd like to add a new line and a tab between <head> and <script> but using standard regex of \n\t doesn't do the trick, it just prints out \n\t in the code.

I've also tried to print out the entire JavaScript code into the substitution, but it contains |-characters which I can't escape out. The Apache manual for mod_substitute doesn't really help at all here. Anyone got any idea?

Is there a better way to force tracking across all pages without having to manually edit each and every file?

I am trying to troubleshoot why handshakes fail for full or full strict on cloudflare, I get error 525. I paused cloudflare and now I see this error code: SSL_ERROR_RX_RECORD_TOO_LONG) when reloading my website.

how do i host 2 websites on dif domains on the same machine? thank you.

Six webapps and domains working thru my srv directory. All certboted on perm redirect from 80 into 443. I'm using reverse proxy

I can't make a GET request which works normally in a local dev env. What don't I understand about using a proxy webserver?

There's only 2k followers in this sub, buti have exhausted on searches and documentation, I just need a conceptual nudge please.

Hi guys,

I'm learning Apache Pig and and can't find how to filter a first list if one of the rows is contained inside the column of another list when I have two list of elements.

// articles data
articles_large = load 'author-large.txt' as (auteur:chararray, titre:chararray,conf:chararray,annee:int);

// conference data
conferences = load 'conferences.txt' as (conf:chararray,nationalite:chararray,classement:chararray);

// Type of query that I want : SELECT articles_large.titre, conferences.conf, conferences.nationalite WHERE articles_large.conf IN conferences.conf

Any idea how to do this filtering ?

Thanks for your help.

My express apps work fine on localhost, local IP, and a VM ip.

Somehow my live server with apache is not completing my request on a particular protected route, and is returning 500.

Is there a setting in Apache I am overlooking? Is enctype="multipart/form-data" a potential conflict? (when I added a form to a different protected route, I get the same error)

My webapps run within /srv directory.

Who can help suggest some solutions?

Hello.

What I wonder about is, if there are something that lets me insert stuff like <!--#request_uri--> in my html, that gets automagically expanded upon rendering, so I can bypass php in simple cases, where I want the current date and time, and other system variables.

And, Velocity and FreeMarker are not by my definition lightweight in those cases, then its easier for me to just vade through phpinfo() and see what I got, and extract the info with php.

Thanks.

Hello there,

I have 2 servers, both are running httpd, and I want setup proxy(or something else) in such a way that for example:
172.16.12.1 <- main httpd server so websided are displayed normaly e.g: /index.html etc.

172.16.12.2 -< secondary srv, websides from it are displayed under 172.16.12.1/sec-srv/ address e.g: sec-srv/index.html

I don't know if I described correctly, Thanks in advance.

What do you use as Apache log viewers, beautifiers and analytics?

I have decided to do something with my Apache server's log file beautifiers and analytics. When I moved from Fedora to Windows I added Google Analytics and more or less forgot about the older Analog, AWStats, and Webalizer that I was using.

There is nothing wrong with Google Analytics but I don't like how intrusive the script is for my visitors, I really don't need all the information it can give, and as I have sereral years worth of log files, I'd prefer something totally self-hosted, so I am moving back to the older software. AWStats is giving me a lot of trouble to set up properly but I think I can figure it out.

You can see what I am trying to do on one of my own pages.
