querystring.clean

STRINGquerystring.cleanSTRINGurl

Available in all subroutines.

Returns the given URL without empty parameters. The query string is removed if empty (either before or after the removal of empty parameters). Note that a parameter with an empty value does not constitute an empty parameter, so a query string "?something" would not be cleaned.

Example

set req.url = querystring.clean(req.url);
