Web Service WSDL Rewrite

Hi David,

If you want to rewrite content in the HTTP response payload, you can use a blank stream profile and STREAM::expression iRule. The iRule would look something like this:

 
  From: 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 https://ourDNS:443/xsdURI with http://ourDNS/xsdURI 
       STREAM::expression "@https://ourDNS:443/xsdURI@http://ourDNS/xsdURI@" 
  
        Enable the stream filter for this response only 
       STREAM::enable 
    } 
 } 
 

Some additional notes:

If any part of the string to search for has periods (https://ourDNS.example.com:443/xsdURI), you should escape them with a backslash (https://ourDNS\.example\.com:443/xsdURI).

If the server compresses responses, you should either disable compression on the server or add an HTTP_REQUEST event to remove the Accept-Encoding header to prevent server compression.

If the find/replace strings are of different length, you should create a custom HTTP profile with chunking set to rechunk and add it to the VIP so the Content-Length header will not be included in responses (with an incorrect value).
