Hello,
I think we're starting to see some of the limits of HTTP being hit.
We're actually quite far from using the full capabilities
of HTTP. We're definitely bumping into limits exposed by
HTTP implementations, though (in the case of Ajax we could
use control over the number of HTTP connections and HTTP
pipelining).
Personally, I'd like to a protocol which allows communication in
both ways.
HTTP 1.2? XMPP/Jabber? Something else?
Exposing XMPP well in a JavaScript API would certainly be
interesting. BEEP is another possibility. However, all of
these would require protocol implementation and API
standardization. If we can do a lot more just by changing
a single parameter, perhaps we should start with that and
then begin work on adding more suitable protocols.
Regards,
Ted.

Ajax applications often make use of multiple concurrent
HTTP requests; in particular Ajax Push (Comet/Reverse Ajax)
makes use of two HTTP connections: one to block waiting for
messages from the server, the other to send messages to
the server.
The problem is that the connection limit for many browsers
is two connections per browser per server. Sophisticated
Ajax applications, on the other hand, need two connections
per window (or tab) per server. This allows each window or
tab to support two-way messaging with the server. Without
it (and without the ability for the two client windows
to communicate and thereby share a single connection) the
two available HTTP connections become consumed by the
blocking message requests.
I would like to propose that the HTTP connection limit
be standardized at two per user-initiated window. (For
instance, Safari is not limited to two connections per
browser.) This should be a relatively straightforward
change in browser policy (browsers other than Safari,
that is), but it is a significant enhancement for
Ajax applications.
