No, $_SERVER["QUERY_STRING"] is empty when there is no query string. If
there is a query string, say the page is:
http://somesite.com/?something
then $_SERVER["QUERY_STRING"]=="something". Check to see if the string is
empty, and if it is empty, then you're OK. If it's not empty, then a query
string has been passed.
