Stream iRule Help

I want this iRULE to modify the returned URL based on HTTP request.     Problem: A8001 is the local server name. It changes from server to server. We don’t want to expose local server name ...

That looks like a good start. Can you replace this portion with matchclass to check the Content-Type header against the datagroup?

Also, can you clarify what Content-Types you want to check in the response? The Content-Type header will contain MIME types--not URIs. So you should probably change this iRule to reference a new class which contains the Content-Types you want to check.

[HTTP::header value Content-Type] contains $::A_URIs_no_persist

[matchclass [HTTP::header value Content-Type] contains $::mime_types_to_check] 

 
 when HTTP_REQUEST { 
    set host [HTTP::host] 
    if { [matchclass [HTTP::uri] contains $::A_URIs_no_persist] } { 
       persist none 
       pool Pool_A 
    } 
 } 
 when HTTP_RESPONSE { 
    STREAM::disable 
    if {[HTTP::status] == 200 and [matchclass [HTTP::header value Content-Type] contains $::mime_types_to_check]}{ 
       STREAM::expression @http://A8001:8001/@http://$host/@ 
       STREAM::enable 
    } 
 }
