Re: [PHP] Shoutbox suggestion needed

The main issue with these systems is updating the client on a regular 
enough basis.
If the content is time critical, like with Facebook chat, then you need 
to do long polling.


However for a Shoutbox, because it's more like an IRC channel with 
people 'shouting' to a channel, you can probably just set the client to 
automatically update on a regular basis. Or even more advanced, would be 
to get it to check in increasing intervals. Firstly it checks 0.5s 
later, then 1s later, then 2s, 4s, 8s, 16s, with a limit of 60s (i.e it 
checks at least once a minute for an update), upon new content being 
received the time is reset back to the 0.5s


If you need to do long polling  
then look into the Tornado Webserver  which 
Friendfeed , and more recently, Facebook use 
(for their LiveFeed system).
For a PHP based implementation check this out

Yeah, but then, generally, you can tell the people visiting this site
what they need enabled, as it looks like the visitors are going to be a
select few. Java is available on all the main browsers, and generally
only needs one to accept the applet. For a chat application to be
written using only Ajax technology, well, like I said before, if
Facebook tried it and still can't get it right with all the financial
backing they have, what hope for someone to release this sort of thing
open source and Facebook not be aware of it?

Strange requirements, but whatever.

A shoutbox is pretty rare on anything except sites aimed at teenagers
so I'm not surprised you haven't had many people jump in and tell you
what they're using, because they're not.

If this is for chatting with the site admin you may want to look into
one of the live support options rather than a shoutbox. They're
private (although I'm sure some have a public option) and they will
provide a much better system for the admin to track multiple
conversations. I really think a shoutbox is the wrong solution for
this particular problem.

I don't know of anything you can use like this, especially that runs
purely on Ajax. Just take a look at Facebook chat. That's Ajax, and
fails and falls over on a constant basis to the point where it is almost
useless. Imho, Java seems to be pretty good at this sort of thing, and

Thanks for your response, but shoutbox isn't a online exam system. Shoutbox
is a chat-like feature that generally work with ajax. Where you can post
quick messages to website. We'll use it for a quick communication with admin
of system.

Here's what wiki says about Shoutbox http://en.wikipedia.org/wiki/Shoutbox.

Forgive me, but I don't know what a "shoutbox" is?

As for an online exam that uses ajax, does this work?

If so, you are free to use anything you find there under GPL.
