Apache :: Web Content Filtering In Proxy Server

Sep 20, 2014

I am using a Windows 7 and the proxy server is working fine. However, I need to run a web content filtering on the server. This should be able to replace or change specific words or phrases from an incoming html and deliver it to the client. I have searched the internet for days for a working configuration but none of them worked. Here is the current configuration I added on the httpd.conf file:

<IfModule mod_ext_filter.c>
ExtFilterDefine add-tm mode=output intype=text/html/php cmd="Apache/bin/GnuWin32/bin 's/Company1/MyCompany1/g'"
SetOutputFilter add-tm
</IfModule>

<Location "/web/">
SetOutputFilter add-tm
OutputSed "s/Company1/MyCompany1/g"
</Location>

I have also uncommented these modules:

LoadModule ext_filter_module modules/mod_ext_filter.so
LoadModule file_cache_module modules/mod_file_cache.so
LoadModule filter_module modules/mod_filter.so
LoadModule headers_module modules/mod_headers.so

Nginx As Apache Proxy For Static Content -- Configuration

Nov 23, 2007

I am a non-tech person trying to configure Nginx to serve static content (apache will remain on port 80 for the dynamic stuff).

Nginx is already installed, what I need is a workable configuration file for nginx so that it serves all static stuff (images and a few folders with static html) and instructions in how to create it. The server is running DirectAdmin panel, Apache 2.24, PHP 5.23 and XCache 1.2.

How To Cache/proxy Streaming Content - More Details Inside

Jun 4, 2008

I've got a dedicated server running my portal. Now we plan to soon launch broadcasting, where we via a webcam + microphone will broadcast (streaming WMV media) to all our members. Our members will then be able to interact with the speakers via chatting.

Now we are currently undergoing loadtesting, with our current setup, which is:

1. dedicated server+ultrafast connection=>chatting

2. home PC with static IP and 1 MBit upload=>Video+Audio Streaming

So the member requests a page from the dedicated server, which has a chat window and a windows media player. The player will retrieve the video/audio content from the home PC. This is done by the client.

Now is pretty logical to see that there will be limitations in how many connections the home pc will be able to handle.

The question is: How do i make the dedicated server get the content from the home pc (so it only serves one connection) and then get all the clients to get their video content from the dedicated server ?

I've looked into the proxy modules for the apache server, however they (forward/reverse proxy) both passes the connection on to the remote machine and thereby not doing what I want to do.

Apache :: Proxy A Single Session Server Behind

Jan 8, 2015

I have diesel generator controller card (IB Lite made by Comap) and the built-in webserver supports only a single user/session connected.

I want to set apache in front and serve multiple connection while apache is keeping a single session with the IB Lite card in background no matter how sessions it have.

I tried ProxyPass but it doesn't seems to be a solution.

Is this possible?

Apache :: SSL For Proxy Server And Individual Web Servers

Feb 27, 2014

I have a total of 3 web servers:

x1 gateway.domain.com:443 (Using as a proxy to web1 and web2)
x1 web1.domain.com:443
x1 web2.domain.com:443

I was able to have gateway.domain.com play nicely with a wildcard certificate and handshake perfectly with web1 and web2. Now currently, web1 and web2 have their own SSL certificates while gateway has a wildcard cert for *.domain.com. Is it necessary to have certs on all 3 servers or just have the single wildcard cert on gateway.domain.com?

Apache :: How To Change URL Of HTTP 302 Returned By Proxy Server

I'm running Apache 2.4.7 on a RHEL 6.4 server.

I would like to have Apache intercept this http 302 and redirect the client to URL...

Apache :: Reverse Proxy Modules - Error Reading Status Line From Remote Server

Oct 17, 2013

We have been using Apache 2.2.x with reverse proxy modules for our clients to access their OWA servers for over a year. I want to get us to Apache 2.4.x so I setup a test box with latest 2.4 on it. I fixed the config file issues since 2.4 has changes in it. OWA proxy is working on my test server with Apache 2.4. But with 2.4 I do have an issue I cannot figure out. Note that this does NOT occur with Apache 2.2. I get the following errors when using ActiveSync through reverse proxy:

[Thu Oct 17 12:19:11.670665 2013] [proxy_http:error] [pid 748:tid 8440] (OS 10060)A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. : [client x.x.x.x:20311] AH01102: error reading status line from remote server mail.nameredacted.net:443
[Thu Oct 17 12:19:11.670665 2013] [proxy:error] [pid 748:tid 8440] [client x.x.x.x:20311] AH00898: Error reading from remote server returned by /Microsoft-Server-ActiveSync

So somehow with Apache 2.4 there is some sort of timeout that was not there with 2.2.

Apache :: Proxy Pass / Proxy Pass Reverse

I'm using the isapi rewrite module for iis 6 which uses the exact same syntax as mod_rewrite in apache. I'm not very well versed in apache and need getting this to work asap. Basically I have a directory in our website: URL....

I need to forward this to an IP address, for example to this address:100.12.33.45/folder.While keeping the original URL (www.xyz.edu/folder). I'm unsure of the apache syntax for this.

Apache: Need Thoughts On Offloading Static Content

May 18, 2009

I'm looking for a way to get a little more mileage out of Apache + PHP environment without losing Apache capabilities. In shared hosting environments, losing features such as .htaccess and a real mod_rewrite are not even on the table. I'm also not willing to accept the performance hit and connection issues that are inherent with FastCGI, so that means mod_php.

In this particular situation, there are two busy sites, which are the problem.

These are a few ideas I've been thinking about.

1. mod_proxy + nginx: mod_proxy sends static content requests to nginx. This requires two sets of vhost files to be maintained.

2. mod_cache: Caching common static content such as page graphics .css, .js, etc.

3. squid

If you've been down 2 or more of these roads, I could benefit from your experience.

Apache :: Setup Dynamic Content Configuration - Correct Headers

Aug 28, 2014

I am trying to setup dynamic content configuration in apache 2.2 httpd conf. Here is the configuration and couple test cases:

CONF:
<FilesMatch ".(js|css|gif|jpg|jpeg|png)$">
Header set Cache-Control "no-cache, no-store, max-age=0, must-revalidate"
</FilesMatch>

TEST 1:
Without <FilesMatch> directive, the headers are set to all requested content as it should. This includes content served from apache server and content from a separate application server.

TEST 2:
If I use the above configuration example, I can see that static content comes with correct headers only

How do you enforce https on the site?

Apache :: Mod Proxy With F5 Load Balancer

May 30, 2013

Apache using mod_proxy -> F5 (hardware load balancer) -> 2 jboss application server

It uses jsessionid. I sometimes get 500 errors for the post methods. I think the request goes to the incorrect jboss server because of the F5 load balancer. Everything works just right when I shutdown one of the jboss app servers.

Apache :: 2 Kerberos SSO Through Reverse Proxy

Apr 24, 2014

I'm trying to do a setup of alfresco.It has two basic sites. [URL]. Both use kerberos authentication. Alfresco has SSO and share has not. Both sites are on the same server (its just one site but different subs)

I want to put this behind a reverse proxy to eliminate the servername:port combination.

When I put it in a normal config with ajp everything works fine for the share website. I can login without problems. Not so however for the alfresco website. I get a browser login request (not the alfresco one) when i enter my credentials he asks them again and again and then he ends on the regular login page of alfresco at which point everything works. The username I entered is displayed at this point. When I do not enter my credentials correct I do not reach the page.

If I remove the SSO from the alfresco website everything is normal (but i have to login)

Apache :: Proxy To SP Can't Log In After Fixing 401error?

Aug 12, 2014

I have apache 2.2 on Linux going through the a firewall to a backend sharepoint server. My sharepoint application has anonymous and authenticated traffic. This works fine most of the time but we randomly get (104)Connection reset by peer: proxy: error reading status line from remote server. I was able to fix this by adding *SetEnv force-proxy-request-1.0 1 *SetEnv proxy-nokeepalive 1 *RequestHeader unset Expect early But after I added this I was then no longer able to log in. I would receive a *HTTP/1.1" 401 my understanding is KeepAlive is required for NTLM to work so making sure I can stop the connection resets which are unacceptable and still allow the authenticated users to log in.

I know that I could just forward the ports through the router, but I don't want all the extra ports opened. I was told that I can have Apache to do a revers proxy, but I can't get it to work. I basically want to be able to do type myname.dyndns.org/sickbeard instead of typing in myname.dyndns.org:8081.

Apache :: Open Proxy On Website

May 23, 2015

I'm trying to fix a problem with open proxy on my website. It's running ubuntu & apache2. I also run pfsense for a firewall with snort. I have a SSL for the website, so I have regular port 80 redirect to https.

At first I did notice right away when I checked & saw this happen that proxy was turned on. So I got that turned off.

My firewall is still allowing these bad IPs to port 80. I would like to figure out what I could turn on the firewall or snort to stop those connections in addition to what needs fixing in apache. I've read the solution is to make the redirects go to a 403 error page.

I also tried adding a mod_security rule but ended up blocking all people from website, though I may have accidentally turned some other rules on too.

There are a few different problems it looks like.

First - It looks like they're trying to connect to my HTTPS then redirect to an ad through my domain name?
Second - It looks like they're still trying to use my website for open proxy but directly accessing ib.adnxs.com through my port 80. My logs indicate I'm redirecting to a 301 page.

Apache :: 2.4.3 Mod Proxy Not Stable In Production

Dec 25, 2013

Have run through a bunch of threads on mod_proxy race conditions, possible causes, and potential solutions.

What is the status? Is there a fix for this, maybe in 2.4.7?

On 2.4.3 in production we literally have 10K errors in the past 2 months along the lines of:

Code : AH00898: Error reading from remote server returned by...

Application server (JVM webapp) issues no errors at the time of mod_proxy error occurring. It seems then that mod_proxy is sporadically broken, which is horrible for end users accessing an otherwise rock solid production application.

Apache :: How To Use Reverse-proxy With Mod Rewrite

Nov 5, 2014

I am running a few different web servers on my home network and have found a way of binding each wb server (and any virtual hosts) to domain names and having a "central" web server rerouting a request to the appropriate server using reverse-proy. at the moment, this central web server is IIS (Windows Server 2008 R2) based and it works perfectly. I want to change the central server to an Apache based one.

As an example; I want the central server to see an incoming http request (e.g sub.domain.com) and reroute it using reverse-proxy to a different web server that wouldn't normaly be accessible from the Internet (e.g 192.168.1.122/index.html).

My question is how do you reverse-proxy to a different server on the LAN with mod_rewrite in Apache?

Apache :: Mod Proxy - Error Page Handling

Nov 10, 2014

a question on mod_proxy. We're using mod_proxy as a simple reverse proxy (ProxyPass & ProxyPassReverse) to reverse-proxy various back-end PHP and Mono/.NET apps.

One problem we see is that when the back-end PHP app suffers an error (e.g. a 404 or 500) , then mod_proxy ignores the nicely-formatted custom error page served up by our PHP app, and instead serves a very plain generic mod_proxy 404 or 500 error page back to the client. Is there a way to configure mod_proxy to serve up the 500/404 error page content which is created by the back-end app ?

(We thought ProxyErrorOverride might work, but it seems to be intended for the opposite scenario, where I want to *ignore* the 404 page content from the back-end and show a mod_proxy-defined error page instead.We're using apache 2.2 on 64-bit CentOS 6.5 ( httpd-2.2.15-31.el6.centos.x86_64 )

Config like:
...
ProxyPass /abc/ http://server4/abc/
ProxyPassReverse /abc/ http://server4/abc/

Apache :: Reverse Proxy - Some Parts Of App Not Working

I have tried ProxyPreserveHost on, ProxyVia full, and some rewrite rules, but I'm not sure what I'm doing Direct access to the port of the app works (i.e. 83.xxx.x.xxx:9900), so i know it has something to do with the reverse proxy.

Apache :: Rewrite Rule Does Redirect Rather Than Proxy

Oct 28, 2014

I just installed httpd-2.4.10-win32 and I can't make mod_rewrite to work :

What I'd want is a proxy to receive a print.xxxx.com/appl uri and forwards to appl.serveur.xxxx.com:8080/streammaster

I do

RewriteCond %{HTTP_HOST} print.xxxx.com
RewriteRule /appl/ http://appl.serveur.xxxx.com:8080/streammaster [P]

and I get a redirect : 192.168.250.50 - - [28/Oct/2014:14:55:19 +0100] "GET /appl/ HTTP/1.1" 302 - mod_proxy is loaded and works of course.

I've tried lot of variations (it works the same in a virtual host without rewritecond) to no avail.
