Component: p2-semantics
Is a request body allowed on GET? Other requests?
Consensus to, in RFC2616 section 4.3:
When a request message contains both a message-body of non-zero length and a method that does not define any semantics for that request message-body, then an origin server SHOULD either ignore the message-body or respond with an appropriate error message (e.g., 413). A proxy or gateway, when presented the same request, SHOULD either forward the request inbound with the message-body or ignore the message-body when determining a response.
as per http://www.w3.org/mid/9C43F5AB-C3D7-4584-8F12-A9F459D3817F@gbiv.com
Fixed in [171].
