Thanks for answering my question last week about max users. I got the chat set up on my website and even fuseboxed it. It works great in Firefox. However, it does not work in IE. I went back to try the demo again, and it doesn't work in IE either. The chat window does not refresh (unless it's a / command). And intermittently it seems that when a new person enters, the existing user in IE is kicked out.

Is this a known bug?

Followup: Seems to only be IE 8.

Definately wasn't known...

Looks like when you join the chat, it calls chatInit then calls getUpdates twice, but then no more.

After a bit of investigation (using an http sniffer for IE called Fiddler), I realized that it only made the ajx call to cfopenchat_interface.cfm?action=getupdates TWICE, and then stopped. But why? The debug panel showed that it was calling it as it should, the timer was working.

CACHE.

Apparently, the cache in IE8 is too smart for its own good.

There are two solutions, and I'm implementing BOTH. The easiest for you to add to your existing code is this...

Open up cfopenchat_interface.cfm. you'll find four instances of this:

   <cfcontent type="text/plain" reset="yes">

After each one, place the following three lines:

   
   <cfheader name="expires" value="#now()#"> 
   <cfheader name="pragma" value="no-cache"> 
   <cfheader name="cache-control" value="no-cache, no-store, must-revalidate">

I'm also modifying cfopenchat.js to add a unix-style epoch timestamp to each URL called with getJSON()

These changes are in subversion now, and will be uploaded as release 1.11 momentarily.

Rick, Thanks for taking a look at that so quickly. I've implemented the changes and everything is working great now. I'm just learning jQuery and I've already learned a lot by looking at your code, but it would've taken forever to figure out this IE nonsense on my own.

Thanks again!

Yeah, Fiddler is REALLY helpful if you have to debug things in IE, because it allows you to really see what requests are being made to the server, and what the servers response is. Firebug gives you that for Firefox, of course...

This appears to be isolated to Windows 7 and IE 8 only...I may be wrong here...I'm running Vista and IE8 with no problems, yet my partner is running Windows 7 and IE8 and having problems with the the chat module. Ricks solutions fixed it it perfectly.....thank you!!!

I'm running XP still so it was a problem on XP with IE8 too. Interesting that it worked on Vista with IE8 though.
