merging two irules into one efficient one.

Hi All, I was wondering if there is a way to merge two irules into one effcient one. The first irule checks the host and if a user is coming in as www.mysite.com, it will rewrite the host head...

Yeah, you'll need the leading forward slash on the second field of the datagroup entries. Can you log the mapping in the iRule and reply with the output from /var/log/ltm? 


when HTTP_REQUEST {

    Check if the Host is www.mysite.com
   if { [string tolower [HTTP::host]] eq "www.mysite.com"} { 

       Rewrite the Host header to www.mynewsite.com
      HTTP::header replace Host "www.mynewsite.com" 

   } else {

       look for the second string in the data group and redirect 
      set newURI [findclass [HTTP::uri] $::newURI-Datagroup " "]
      if { "" ne $newURI } {
         log local0. "Mapped [HTTP::uri] to $newURI"
         HTTP::redirect "https://www.mynewsite.com$newURI" 
      } else {
         HTTP::redirect "https://[HTTP::host][HTTP::uri]" 
      }
   }
}
