Removing /string/ from URL

Hello,

 

I would like create a iRule which removes only a /string/ from a URL and this is given to a pool of tomcat servers. Which practice would have the less impact on the performance?

 

Thanks!

    Try something like this..

    Option 1

    If you want to redirect to new URI from client browser, try below irule. When using this, client would be able see the new url (after removing /string). [URI Redirect method]

    when HTTP_REQUEST {
    if {[string tolower [HTTP::uri]] starts_with "/string"}{
        set newuri [string map -nocase {"/string" ""}[HTTP::uri]]
        HTTP::redirect "http://[HTTP::Host]$newuri"
        }
    }

    Option 2

    If you dont want client to see the new url, try below irule. On the client browser it won't make any changes but the backend it will remove /string. [URI Rewrite method]

    `when HTTP_REQUEST {
    if {[string tolower [HTTP::uri]] starts_with "/string"}{
        set newuri [string map -nocase {"/string" ""}[HTTP::uri]]
        HTTP::uri $newuri
        }
    }
