iRule only runs once

Hi Greg,

Sorry to hear that you haven't been able to get concrete help with this yet. As Claud said, I would actually suggest you go back to the stream profile option and use a STREAM::expression based iRule to do this replacement in the HTTP response payloads.

http://devcentral.f5.com/wiki/default.aspx/iRules/stream__expression

You don't need to do the HTTP request payload collection in his example. But the response stream profile config should work well:

 Example which replaces http:// with https:// 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 www.xyz.com with www3.xyz.com
      STREAM::expression {@www\.xyz\.com@www3.xyz.com@}

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