Transporting blank values in URL queries

URLs can transport key/value pairs ("parameters") using this syntax:


If the value is blank, mind these subtle differences:

URL Meaning
/path?foo= Parameters have a key foo. Its value is an empty string.
/path?foo Parameters have a key foo. Its value is null.
/path Parameters have no key foo.
