Webrick however replaces plus signs with spaces, which violates the spec and causes a loss of information. An encoded plus character (%2B) is correctly decoded by Webrick. This bug affects Ruby 1.8, 1.9 and 2.0. $ irb irb(main):001:0> require "webrick" => true irb(main):002:0> WEBrick::HTTPUtils::parse_query("a+b c") => {"a b c"=>""} irb(main):003:0> WEBrick::HTTPUtils::parse_query("a%2Bb%20c") => {"a+b c"=>""} irb(main):004:0> ^D -- http://bugs.ruby-lang.org/
