ClickOnce and URL parameter

Question

Hi,
I need to pass some URL parameters in the query string of a ClickOnce application. I read the msdn article to do that, but I cannot reach to do it.
I checked the right option to enable query string parameters and I set only online run; I've a button in an ASP webapp that make postback to the url of the ClickOnce: "http://servername/GCI/publish.htm?xxx=yyy", but it says that it doesn't exist. I tried also "http://servername/GCI/GCI.application?xxx=yyy", but it's the same...

If i go to "http://servername//GCI/publish.htm", I can run the application, but without URL parameters...
So, where I'm wrong?
