HTTP redirect to full URL Path

Do you want a redirect, i.e. HTTP redirect sent back to client, or are you looking to rewrite the hostname and path on the F5 before forwarding traffic on to the backend servers?

Also you want to redirect/forward to add uri on, e.g. http://application.bob.com/app1 to http://back_end_node/application_path/app1

Redirect:

when HTTP_REQUEST {
    if {[getfield [HTTP::host] : 1]  eq "application.bob.com"} {
        HTTP::redirect "http://back_end_node/application_path[HTTP::uri]"
    }
}

 Forward:

when HTTP_REQUEST {
    if {[getfield [HTTP::host] : 1] eq "application.bob.com"} {
        HTTP::header replace "Host" "back_end_node"
        HTTP::uri "/application_path[HTTP::uri]"
    }
}
