Simultaneous AJAX calls with Prototype?

[cmercier]

Hi everyone!

I am using the Prototype library and ran into a serious limitation. I
need to make many concurrent AJAX calls to the server, but Prototype is
queueing them instead. Obviously, this is slowing my web application a
lot.

Is it a Javascript or Prototype limitation? If Prototype is in cause,
is there a work around? I'd rather keep Prototype since I also use
script.aculo.us.

Thank you!

Carl

Prototype.js is junk.

Depends. It could be an HTTP limitation. Clients are only allowed 2
connections to a server at a time using HTTP/1.1 (afaik). So your browser
may be queuing many requests.

I don't know how prototype does ajax, but you can also check out my lib at
http://www.AjaxToolbox.com/ which I know for sure does not queue up
requests.

If prototype doesn't have a support forum, it needs one. You should suggest
it to the author. Too many questions end up here.

Clients that use persistent connections SHOULD limit the number
of simultaneous connections that they maintain to a given
server. A single-user client SHOULD NOT maintain more than 2
connections with any server or proxy.

The phrases 'SHOULD' and 'SHOULD NOT' being very strong recommendations
as far as the RFC is concerned.

I don't think that there are limits to non-persistent connections, but
Firefox only allows eight per server by default.
