Using IIS7 as a reverse proxy

iis-7reverse-proxy

My question is pretty much identical to the question listed but they did not get an answer as they ended up using Linux as the reverse proxy.

Using IIS7 as a reverse proxy

I need to have IIS the main site and linux (Apache) being the proxied site(s).

so I have

site1.com (IIS7)
site2.com (Linux Apache)

they have subdomains of

sub1.site1.com
sub2.site1.com

sub3.site2.com

I want all traffic to go to site1.com and to say anything that is site2.com should be proxied to linux box on internal network, (believe ARR can do this but not sure how).

I can not have it running as Apache doing the proxying as I need IIS exposed directly.

any and all advice would be great.

EDIT

I think this might help me:

<rule name="Canonical Host Name" stopProcessing="true">    
    <match url="(.*)" />    
    <conditions>    
        <add input="{HTTP_HOST}" negate="true" pattern="^cto\.com$" />  
        <add input="{HTTP_HOST}" negate="true" pattern="^antoniochagoury\.com$" />   
        <add input="{HTTP_HOST}" negate="true" pattern="www.antoniochagoury\.com$" />   
    </conditions>    
    <action type="Redirect" url="http://www.cto20.com/{R:1}" redirectType="Permanent" />    
</rule>

from: http://www.cto20.com/post/Tips-Tricks-3-URL-Rewriting-Rules-Everyone-Should-Use.aspx

I will have a look at this when I have access to the IIS7 box.

Thanks

I swear this has been answered several times already.

You need to add two pieces of software to IIS to use it as a reverse proxy: URL rewrite and application request routing (ARR). Both can be downloaded from the IIS web site.

The documentation to get you started can be found there.

How to manipulate default document with rewrite module on IIS7

You have two options. One is to keep going down the path that you're on. At a high level the issue with the canonical url rewrite issue is with the action. You can use {HTTP_HOST}, so the action should be something like www.{HTTP_HOST}/{URL}. That makes it dynamic based on the domain name entered rather than having it set to a specific name.

However, you may find it easier to continue to use the default docs. The way to do this per site is to use location tags within applicationHost.config. You can't do it the standard way within IIS Manager because, as you pointed out, it shares the same config for all sites. There are 3 fairly easy ways to do it (not counting the programming options). One is with Configuration Editor, another is with appcmd and the 3rd is with notepad or an editor directly.

I'll describe here how to do it the Configuration Manager way. First, make sure that you have it installed: http://www.iis.net/download/AdministrationPack

Then using IIS manager, navigate to the site you want to change the default doc for. Open Configuration Manager. In the top left drop-down, change to system.webServer/defaultDocument. In the top right, make sure to change to the ApplicationHost.config option. In the main window, select the 'files' row and click the (...). The rest is straight forward.

Dynamic Reverse proxy with Apache 2

What's wrong with a two liner like:

The 1-21 case.

#!/bin/bash

while [[  $(( $i < 21 )) != 0 ]]; do
  cat << EOF
  <VirtualHost *:80>
    ServerName reverseprox$i
    ServerAlias site$i.domain.com
    ProxyRequests Off
    ProxyPass / http://site$i.domain.com/
    ProxyPassReverse / http://site$i.iisserver.internald.com/
    ProxyPassReverseCookieDomain site$i.iisserver.internald.com site$i.domain.com
  </VirtualHost>
EOF
  i=$(( $i + 1 ))
done

The anything - case.

It prints all the records you need to add to your conf file.

#!/bin/bash
#Read a file, or query a db somewhere.
for i in  $(cat /path/to/namelist); do
  cat << EOF
  <VirtualHost *:80>
    ServerName reverseprox$i
    ServerAlias $i.domain.com
    ProxyRequests Off
    ProxyPass / http://$i.domain.com/
    ProxyPassReverse / http://$i.iisserver.internald.com/
    ProxyPassReverseCookieDomain $i.iisserver.internald.com $i.domain.com
  </VirtualHost>
EOF
done
