Hi Moritz,

I'd suggest using a stream profile and STREAM::expression based iRule to do this instead of trying to buffer the payload with HTTP::collect / HTTP::payload.

Here is an example: 

 
 http://devcentral.f5.com/wiki/default.aspx/iRules/stream__expression 
 when HTTP_RESPONSE { 
  
     Disable the stream filter by default 
    STREAM::disable 
  
     Check if response type is text 
    if {[HTTP::header value Content-Type] contains "text"}{ 
  
        Replace somestring with foobar 
       STREAM::expression "@somestring@foobar@" 
  
        Enable the stream filter for this response only 
       STREAM::enable 
    } 
 }
