Well I have a very rough version of gomoku working now. I'm using Jquery, Php and mysql database.
When a user clicks on a board square a piece is placed. An ajax refresh determines if turn count has been incremented and updates the board's html if necessary.
The problem is that Internet Explore (6,8,&probably 7) caches the page on the first visit. Even if the page is refresh manually the cached content will remain.
I tried using
<META HTTP-EQUIV="cache-Control" CONTENT="no-cache">
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
on the html page with no luck. Only way to get an update is to delete the files though the tools.
I hope this is enough information. If not I'll try to answer questions as best as possible.
Update 3 I got it working I used the .ajaxSetup Thanks phoenix, tim, and everyone else.
