			<![CDATA[I've coded an AJAX chatroom, where the client sends a request to check for new messages every .4 seconds. Unfortunately every once in a while the request doesn't go through, which doesn't matter so much for checking messages, but logging on/off the chatroom uses the same method, and the list of users online doesn't update properly if the request doesn't go through. How do I make the client wait until the server is free to send requests?]]>

			<![CDATA[If you're having problems, don't use AJAX for the critical requests. Refresh for logging in and out.<br />Also, how did you come up with .4 seconds? That seems a little much... I would think that you could check once a second, and then you're only putting 40% as much stress on your server. If you do that, you'll be able to process more requests.]]>

			<![CDATA[0.4 seconds was a result of testing with a couple people, general consesus was that it should be that responsive. It massacred the server, so I did some tweaking and it runs along pretty well with 5-6 people.<br />Logging in and out is actually just loading and unloading the site, with an ajax request on sign out. I brought the refresh back up to 1 second but the problem persists, even with just one user online. Is there no way to check whether the server is busy, and resubmit the request until it goes through?]]>

			<![CDATA[I'd need to see some of the PHP to help more. The only suggestion I would have so far is to use some more "best practice" AJAX... Don't use innerHTML, but rather DOM methods. And don't return HTML from a PHP script (which you look to be doing for your user list), but return XML, and let javascript parse it.]]>
