two tomcat servers using same port, rewrite rules for iis

I have been using ARR and rewrite rules to easily access my Tomcat application.

Like if the application is running at: http://localhost:8090/alfresco

After the rewrite rule it can be accessed on: http://localhost/alfresco

Here is an example of the rewrite rule I have been using that works perfect:

<rule name="ReverseProxyInboundRule1" enabled="true" stopProcessing="true">
    <match url="(alfresco.*)" />
    <conditions logicalGrouping="MatchAll" trackAllCaptures="false">
        <add input="{CACHE_URL}" pattern="^(http?)://" />
    </conditions>
    <action type="Rewrite" url="{C:1}://localhost:8090/{R:1}" />
</rule>

Now the problem I am facing is that I have another local server which has this same tomcat application name and port. Now I want to develop a rewrite rule so that when I visit: http://localhost/alfresco1

it should take me to that server which url is: http://172.23.1.168:8090/alfresco

You could use the following configuration:

<rule name="ReverseProxyInboundRule1" enabled="true" stopProcessing="true">
    <match url="^(alfresco)1/?(.*)" />
    <conditions logicalGrouping="MatchAll" trackAllCaptures="false">
        <add input="{CACHE_URL}" pattern="^(http?)://" />
    </conditions>
    <action type="Rewrite" url="{C:1}://172.23.1.168:8090/{R:1}/{R:2}" />
</rule>
<rule name="ReverseProxyInboundRule1" enabled="true" stopProcessing="true">
    <match url="^(alfresco)/?(.*)" />
    <conditions logicalGrouping="MatchAll" trackAllCaptures="false">
        <add input="{CACHE_URL}" pattern="^(http?)://" />
    </conditions>
    <action type="Rewrite" url="{C:1}://localhost:8090/{R:0}" />
</rule>

What it does:

  • If the url starts with alfresco1, it rewrites it to http://172.23.1.168:8090/alfresco/requested_path using the {R:1} and {R:2} back references.
  • If the url starts with alfresco, it rewrites it to http://localhost:8090:8090/alfresco/requested_path using the matched string back reference.

This configuration is based on the fact that:

The rules are evaluated in the same order in which they are specified

The order the rules are defined in the configuration file is important.
