We were able to achieve this in IIS using below rewrite configuration, was wondering if theres
any module that I can use in apache to achieve the same.

          <rule name="Adjust context root" preCondition="matchReq">
            <!--Check if the Response URI location from Application Redirect starts with
/gtaapp (Application context) and if so, prefix /services/gta  as required by Torbit-->
            <match serverVariable="RESPONSE_LOCATION" pattern="^(\/gtaapp\/)([\w\-\.]+[^#?\s]+)(.*)?(#[\w\-]+)?$"
ignoreCase="true" />
            <action type="Rewrite" value="/services/gta{RESPONSE_LOCATION}" />
            <preCondition name="matchReq">
              <!--Ensure the request is from external user. This can also be determined
based on a new HTTP header added by Torbit, if required-->
              <add input="{HTTP_HOST}" pattern="^$" ignoreCase="true" />

Thank you Matt for response.

We don’t have control on external proxy server its Torbit managed by other team.

We have all firewall rules opened and communications between internal and external.

Below are request and response we are looking for.

Request ::
End user access this url in AEM (<>)
—> Torbit ( Proxy pass<>
 —> ) —> Apache 2.4
—> WAS Application Server ((Application with context root “gtaapp” )


Response ::

WAS Application Server (Application with context root “gtaapp” ) —> Apache 2.4
 (here we are looking to send response as  based
on HTTP_HOST in header set to<> in Torbit) —>
Torbit ( proxy pass —><>
—> AEM/Client<>

Internal users access application directly hitting Apache 2.4 virtual.
External users will access application from AEM which appends additional context root “\services\gta”
which is not actual context root of Application.

I’m looking to change  to
whenever apache sends response back to torbit so that torbit can identify correct path in
AEM and load request to user as<>

Torbit passes HTTP_HOST with value as<> in header
so that I can filter based on http_host and do this only for the requests coming from external
so that it doesn’t affect internal users.

I tried to use substitute module which quiet didn’t work.

There are bound to be other approaches, but one method is to configure the
server as a reverse proxy.  This assumes you have control of the web server running on

Subject: [users@httpd] Updating Response url from Apache

Hello Team,

                We are currently using application internal to our network using something
like below<Application_Context_Root>/menu.jsp<>

We are working to expose our application to external users we use an additional component
Adobe Experience manager for accessing application which appends and additional context root
in request header before even hitting our proxy server in DMZ which proxies request to internal.
Now our request for external users will be.<Application_Context_Root>/menu.jsp<>,
when it redirects to internal Apache web server and when internal web server responds back
to external its not appending additional context root in header /services/app due to which
it's failing.

I’m looking for my internal Apache web server to identify any request coming to the internal
Apache web server from<> sends a response back
to external by appending /services/app to the header before Application_context_Root.

I think I may not be able to use rewrite module to achieve, I’m looking at substitute module.
Is there a way I can add a condition to substitute module and append it to response header
from apache?

Any request that comes to Apache from<> or Proxy
server should be filtered and in every response that apache sends to this requests  I need
to add “/services/app” to header before application context root.
