Description Jake Archibald 2017-05-30 04:58:05 PDT 
Safari never seems to match POST items in the push cache, so allowing them to be pushed is a waste of bandwidth.

Firefox and Edge currently reject pushed POST requests.

I built a little test suite thing for this: https://github.com/jakearchibald/http2-push-test/

The test is served at /push-post/. /push-post/ is pushed with method POST, but making a post request to this URL does not match it.

Oh, it's also a violation of the spec, since POST requests aren't "safe" http://httpwg.org/specs/rfc7540.html#PushResources

The fix for this issue was needed outside the WebKit project, therefore this is being resolved as 'Moved'.

This should now be fixed in shipping software.
