LTM+APM Mode and Other URL links

This is fairly new to me so I don't completely understand have to proceed. However, I have a lab VE environment and can play all I want 🙂 So far, I have written the following rule:

 Replace http://otherinternalserver/ with https://portal-dev.outsideserver.com/ in response content
 Prevents server compression in responses
when HTTP_REQUEST {

    Disable the stream filter for all requests
   STREAM::disable

    LTM does not uncompress response content, so if the server has compression enabled
    and it cannot be disabled on the server, we can prevent the server from 
    sending a compressed response by removing the compression offerings from the client
   HTTP::header remove "Accept-Encoding"
}
when HTTP_RESPONSE {

    Check if response type is text
   if {[HTTP::header value Content-Type] contains "text"}{

       Replace http://otherinternalserver/ with http://portal-dev.outsideserver.com/
      STREAM::expression {@http://otherinternalserver/@http://portal-dev.outsideserver.com/@}

       Enable the stream filter for this response only
      STREAM::enable
   }
}

When an outside user connects to https://portal-dev.outsideserver.com/, they see the internal server as before the rule was implemented. Now however, when they hover over the other internal server link on the page, their link displays the "https://portal-dev.outsideserver.com/" as I would expect. But basically the link does not work and responds with a 404 page not found.

Kevin, is this the correct approach? I think I understand why I need to have a different outside VS for the link, just wanted to make sure I'm going down the correct path..

Thanks, dg
