Netscaler Knowledgebase

First, thanks for the site. Most of my experience is with localDirectors and haproxy so I've made great use of the info here.

I've got a responder on my Netscaler:

add responder action redirect_to_www respondwith "\"HTTP/1.1 301 Moved Permanently\r\n\" + \"Location: http://www.domain.com\" + HTTP.REQ.URL.PATH + \"?\" + HTTP.REQ.URL.QUERY + \"\r\n\"" -bypassSafetyCheck YES

This works great, except if a request hits the policy that uses this responder without any query params, it still gets a "?" at the end of the URL, and gets redirected to: "http://www.domain.com/?"

Is there any way to add the `\"?\" + HTTP.REQ.URL.QUERY' only if HTTP.REQ.URL.QUERY is not empty?

I admit this is pretty much just a cosmetic thing, but it bugs me.
