Re: [hybi] Frame size

[Greg Wilkins <[e-mail]>]

I thought one of the key arguments for a limited frame size,
is that we could avoid the need to consider end points that
could not store an entire frame in a buffer at once.

So 2 byte's can still result in a 64k maximum frame size that
some devices might baulk at... but not many.

However, if frame sizes were 4 bytes or more, then we have the
issue that all end points will have a restriction of frame size
that can be held in a buffer that is smaller than the maximal.
We then need error handling for when a frame that is too large
is offered etc.

So if we are going to limit it, then is should be small
enough so we can say that all websocket endpoints must
be able to accept a minimal frame.

In fact, I would argue for a 16k max frame size with 2
bits given over to help with partitioning and aggregation,
but with no requirement that an endpoint can handle
aggregation and partitioning (unless they indicate they
can in the handshake).
