You can use the ProxyPass or ProxyPass for LTM v10 to rewrite the host and/or URI (as opposed to redirecting the client).

It supports string and regex substitution. If you just want to rewrite the host and URI in requests, you could do this using a simpler iRule that calls HTTP::uri and HTTP::header replace Host $new_host in the HTTP_REQUEST event. You'd want to avoid using regexes if possible as string functions are more efficient.

 

 

If you try either option and run into issues, can you post the iRule you're testing and log entries from /var/log/ltm showing the issue?

 

 

Thanks,
