the same thing doesn't work for test.aspx#var=test

The Fragment Identifier (#) is client-side only, you can't get that from server side code.

#var=test is not q query string. That's part of the "URL Fragment". In a URL to a web page, it indicates which <a> tag to go to.

I don't think the part of the url after the # is passed to the web server directly. To access it you would need to do some javascript processing to pass it on.
