querystring.clean

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);
