Replace host based on file type

Hi Rogerio,

Something like this?

when HTTP_RESPONSE {
    Check if the Content-Type header value matches our criteria
   if {[HTTP::header value Content-Type] contains "somestring"}{
      log local0. "[IP::client_addr]:[TCP::client_port]: Matched the Content-Type check for [HTTP::header value Content-Type]"
       Initialize a variable to save the cookies
      set cookie_string ""
       Loop through each Set-Cookie header.  Save the value to a string, and remove the header.
      while {[HTTP::header exists Set-Cookie]}{
          Append the current Set-Cookie value to the cookie string
         append cookie_string [HTTP::header value Set-Cookie]\;
         log local0. "[IP::client_addr]:[TCP::client_port]: Current \$cookie_string: $cookie_string"
          Delete the current Set-Cookie header
         HTTP::header remove Set-Cookie
      }
       Include the cookies in the 302 response if there were any
      if {[string length $cookie_string]}{
         log local0. "[IP::client_addr]:[TCP::client_port]: Redirecting with cookies to: http://example.com Set-Cookie $cookie_string"
          Send the 302 redirect response with the cookies
         HTTP::respond 302 Location "http://example.com" Set-Cookie $cookie_string
      } else {
         log local0. "[IP::client_addr]:[TCP::client_port]: Redirecting without cookies to: http://example.com"
          Send the 302 redirect response without the Set-Cookie header as there weren't any cookies
         HTTP::respond 302 Location "http://example.com"
      }
   }
}

I didn't test it, but it passed an iRuler syntax check. If you run into problems with it, check the /var/log/ltm log file for debug output. Make sure to comment out or remove the logging before using the iRule in production.
