Reverse Proxy Apache ==> IIS, Need Custom Error Pages Triggered On IIS Side
Dec 3, 2008
I'm not sure if this is the right forum, or if anyone can suggest a message board where I might get support on this.
This is what I have. I have Apache and IIS both running on Windows 2k3.
Apache is running in reverse Proxy mode sending multiple domains/virtual hosts to IIS.
ProxyPass / http://localhost:8080
ProxyPassReverse / [url]
Now, if I type in [url]everything works great and IIS (listening on 127.0.0.1:8080) serves the page. However, I am doing custom error trapping, so when I type in [url](and /mydirectory doesn't exist on IIS) I need to fire ASP code (via custom error messages/handling) on the IIS server and then present a data driven page.
However, Apache is returning A 502 error:
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /mydirectory.
Reason: DNS lookup failure for: localhost:8080mydirectory
Is there a way for me to setup Apache to pass all error checking to IIS while using it as a reverse proxy?
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.
I am trying to control access to an asp page by using windows resource groups. The virtual directory in IIS has both 'Integrated Windows Authentication' and 'Basic Authentication' checked.
When an unauthorized user tries to access this page, it prompts thrice for the user ID and password before going to the 'user not authorized' page. I want it to display the error the very first time an unauthorized user tries to access this page and not ask him thrice before throwing the error page.
The operating system being used is Windows 2003 server.
i have a server with whm/cpanel and would love to have custom error pages that work server wide not just for a specific domain. I have tried adding the "ErrorDocument 404 errors/404.htm" to the httpd.conf file but it doesn't work.
I have no trouble getting custom errors to work for a specific domain but can't seem to get it to work server wide.
Has anyone else tried to tackle this and actually had success?
Being relatively new to the Linux world, I don't exactly know why my reverse proxy settings are not working. Nothing i have tried has worked.
The code below is from my old windows server what does not seem to be working in my new 1&1 vps server. I have the below code at the moment at the bottom of my httpd_ip_defult.conf file under /var/www/vhosts/system/mydomain.com/conf/
The following errors also show up in my vhosts error log:
[Sun Oct 12 23:30:56 2014] [error] (70007)The timeout specified has expired: proxy: HTTP: attempt to connect to xxx.xxx.xxx.xxx:8008 (xxx.xxx.xxx.xxx) failed [Sun Oct 12 23:30:56 2014] [error] ap_proxy_connect_backend disabling worker for (xxx.xxx.xxx.xxx) I also have mod_proxy.so , mod_proxy_http.so and mod_proxy_html.so all enabled in my main httpd.conf file at /etc/httpd/conf/
Basically, I need to fix this urgently as a core feature of my site relies on this setup.
I m trying to setup a reverse proxy with several site that will redirect the request into several internal server.I wanted to do that with several VirtualHost (like shown below). Unfortunatly whatever I type on my browser testsupport.xxxx.com or support2.xxxx.com I m redirected at the first of the config file (in the exemple http://10.253.12.41/.Is it the ServerName key that will redirect to the right proxypass ?
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)
I'm currently in the process of configuring a red hat linux server as a proxy server for a number of back end web servers. I set up reverse proxying to hide the web server url's, but I've run into a problem with the second web server, because some of the directory structures are identical on both servers.
I am having a little trouble getting a reverse proxy redirect to work. I have a Linux server running Apache2. I have installed SABnzbd+, Sickbeard, Couchpotato & Headphones onto this device. I want to access SABnzbd+, Sickbeard, Couchpotato & Headphones from the outside world (via a DYNDNS name).
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.
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?
I am trying to set up a reverse proxy to the application Surveillance Station on my Synology NAS. Altough the reverse proxy works ok for other apps like Webadmin, Download Station and such, parts of the Surveillance Station app do not work, particulary the Live View & Time Line.
From the logs, I suspect an authorisation problem (because of the 401), but I'm not sure. 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.
I've been working with the Apache server (primary under CentOS, but some under Red Hat and on XAMPP stacks as well) and have been tasked with a project.
Periodically, we need to have our web sites down for maintenance - updates, backups, etc. What I've been told to do is find a way to have a 'front end' to our web sites so that, when they are down for maintenance, that then end-users will receive a message 'This site is down for maintenance till XX:XX AM/PM' or such.
Here are my questions:
- What would you call what I am trying to setup? The reading I've done implies that what I really want to setup is a reverse proxy server. Is that what I want to do? - If it isn't a reverse proxy I want to set up, what do I want to setup? - Of the different types of solutions available, What I could use for this? I've read about using Nginx in front of Apache, I've heard of Squid, I've heard about Tomcat. - Is this a type of 'clustering/high availability' project I'm really looking at here? I've been hearing those terms thrown about as well.
In case it makes any kind of a difference, the Apache instances are pretty simple - PHP, MySQL and that's about it - not very involved (for now). I'm hoping that I can learn what/how to do this correctly and, when I'm ready to add more capabilities, that I'll be able to extrapolate out from there what I'd need to do.

For learning purpose I am configuring a blackberry enterprise server(bes) on server3. It's a clean installation with only the needed applications to run a bes. Because I only have 1 public ip I am trying to reverse proxy this webservice two like server1. The bes webservice is configured to accept connections on port 443. So my first web.conf setup was similar to the setup I used for server1 but I noticed that the webpage was displayed but I couldn't interact with the page because it was a java application. So digging deeper into this i found that the webpage that bes provided me to use isn't the real application but more like a iframe setup.
Example: BES Console address: https://server3.com/webconsole/login Real address: https://server3.com/websconsole/app
Unfortunately after finding this and editing my web.conf to proxypass reverse to this real address I encountered a other problem. The bes webconsole works with session is and parameters
Currently i am trying to install an Apache 2.4.3 as a caching reverse proxy. I would like to use memcached as my cache backend. I figured out there is a mod_socache_memcache, which from my understanding, should do exactly that(in combination with mod_cache_socache). So i compiled mod_cache_socache from trunk, loaded mod_cache, mod_cache_socache and mod_socache_memcache, but now i am stuck with the configuration. Here is what i tried:
where do i configure the path to my memcached instance? The reason for memcached as chaching backend, is that the machine is a windows machine, and from my understanding mod_cache_disk is not as efficient on a NTFS filesystem as it is on EXT3/4.
Another reason is, that later on there should be a possibility to put a second Reverse Proxy machine which shares the cache with the first one by using the same memcached instance (is that possible at all?).
I am trying to do reverse proxy for several web servers in my network.I have successfully configure the reverse proxy.However , when website with multimedia webpages are requested , the multimedia content is not displaying. What is is that I am missing in my config file.
I have an Apache reverse proxy set up. I have an IIS server on the backend with a site which must be HTTPS and must require client certificates (x509). It seems like the proxy is working great, but the client certificate is not getting passed along the HTTPS request from proxy to IIS. We keep getting 403.7 (Client certificate required) errors. How I can bridge the client certificate from Apache reverse proxy to IIS?
Our Apache proxy is not set up to require client certs, the IIS website is. What I would expect is that when we make a web request that goes through the proxy to the IIS server, that we would get challenged for a client cert for the IIS website (its set to require client certs like it always has) and that client cert information would be passed along the HTTPS request. We have to be able to programatically access the x509 cert through code on the IIS website, thats why we need to have the cert passed along.
I've set up a reverse proxy using the Ubuntu Apache2 package (2.2.2, with evidently an old version of mod_proxy_html), and it's about 50% functional, but certain images aren't loading.
I've tried with and without ProxyHTMLExtended on, but even with it on I'm not convinced that any non-inline scripts or CSS files are being properly handled, as they are being directed to my local root directory instead of /app1/, and when it is on, I can no longer log in to the internal webapp.
In the log, the only errors that stand out to me are those referencing things from relative root directories, like /images/* and /ajax/*. The image files are coming from separate CSS files, and it doesn't tell me where exactly the ajax references are originating.
Here is the relevant part of my VH config:

My system consist of Ubuntu 14.04 server running LAMP. I am running Apache 2. On the same machine I am running Shiny server and running my apps through port 4949.
I also am running an additional Shiny server copy on a virtual box through port 3838. All is running very good. I have an html web page running on Apache 2. I can view it and all my apps running on both Shiny servers from any place on the web.
My concern, however is security. I have port 3838, 4949, and 80 open. How can I set up Apache to run as a reverse proxy for my both of my Shiny servers (ports 4949, and 3838) and also continue to host my web page securely.
I have also attempted to set up a self-signed certificate using the following procedure but it is not working. I used the following instructions and followed them verbatim.
How to set up a reverse proxy for my Shiny servers?
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:18.104.22.168/folder.While keeping the original URL (www.xyz.edu/folder). I'm unsure of the apache syntax for this.
My server is Win2003 Standard with IIS 6. I'm using IIS6 to host websites but i have a need to run subversion which require Apache. I'm wondering would it cause any problem with my current operation. Apache will run on different port than the standard 80.
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 )
