replace path with Policy Ltm or irule

Hi all

Im using my F5 BIGIP (v14) as reverse proxy to publish some websites by using local traffic policies.

But i need to perform a URL rewriting. To be specific, i need to strip a string from the URI path.

When applied as IRule it works correctly as I want:

when HTTP_REQUEST { if { [string tolower [HTTP::uri] ] starts_with "/path1" } { HTTP::uri [string map {"/path1/" "/"} [HTTP::uri]] } }

But when using local traffic policy it does not work as expected:

Replace - HTTP Uri - PATH ... with value... tcl:HTTP::uri [string map {"/path1/" "/"} [HTTP::uri]]

Am i doing something wrong? What would be the correct way?

PS:  I want replace path1 with an empty string

Thanks all!
