removing part of uri in redirect

Below is my iRule, In this particular case, applications is always there, but where I have testapp and beyond that will change. This particular application 'testapp' needs to go to a different pool and have the beginning of the URL change from http://testsite.com/applications/testapp/... to https://testsite.com/testapp/...

 

The host will always remain the same and in this particular irule, testapp will always remain the same, but what follows after testapp/ will change based on code in the application.

 

 

The line HTTP::redirect "https://[HTTP::host][HTTP::uri]" is what I need to change to drop the /application from the URI.

 

 

when HTTP_REQUEST {

 

if { [HTTP::host] contains "testsite.com" } {

 

if {[string tolower [HTTP::uri]] starts_with "/applications/testapp/" } {

 

HTTP::redirect "https://[HTTP::host][HTTP::uri]" }

 

}

 

}
