Sadly there's nothing official for HTTP. This strikes me as a bit daft, because the spec allows a surprising amount of leeway, and there's actually a surprising amount to it in terms of annoying fiddly syntax. (I have no idea in whose interests this is intended to be, because both client and server have to both read and write this stuff. If they'd decided to make one case complicated so the other could be simple, that would be understandable, if barely less annoying.) And-HTTPD comes with some test data: http://www.and.org/and-httpd/ http://www.and.org/and-httpd/ (I've not looked into this in any depth, except to note its existence, but I wish I'd seen it when I was working on my server. The chap also has an amusing page about the HTTP spec, which I basically agree with: http://www.and.org/texts/server-http http://www.and.org/texts/server-http) For Web Sockets, there's a good test suite here, but again, it's not official: http://autobahn.ws/testsuite http://autobahn.ws/testsuite
