What is HTTP Part V - HTTP Profile Basic Settings

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 
    } 
 }

What are the symptoms of the issue?

 

 

Do you get a response back from the VIP, but it doesn't have the response rewritten? If so, you could check the configuration of the stream expression. It is case sensitive. Another possibility is that response compression is enabled on the server. You can either disable it on the server or add code to the iRule to remove the Accept request header. This prevents the server from sending compressed responses.

 

 

Do you get a page cannot be displayed message in the browser? If so, this is probably indicative of LTM sending a TCP reset to the client. This could be due to a TCL error. You can check the /var/log/ltm log file for details.

 

 

Else, is there another symptom?

Aaron,

 

 

got it - after i edited the irule to remove the accept request header like you suggested, it worked - since i had compression enabled on all the servers servern the www-content.

 

 

thanks a lot!
