Method: Rack::Utils.parse_query

Defined in:
lib/rack/utils.rb

.parse_query(qs, d = nil, &unescaper) ⇒ Object

Stolen from Mongrel, with some small modifications: Parses a query string by breaking it up at the ‘&’ and ‘;’ characters. You can also use this to parse cookies by changing the characters used in the second parameter (which defaults to ‘&;’).
