problem in caching

[Majid]

Hello,

I wrote a PHP program to run in my computer (I use this program as a application and in IE)

I have a huge problem and that is caching in browsers.
for example when I add a record , my program refresh the page but the new record don't listed so I should refresh the page with Ctrl+F5 to view new record.
what should I do ?
I use AJAX for this list of records and many of this program use JavaScript codes.

P.S: sorry for my bad English .

Regards,
Majid

In some version(s) of Opera the browser would cache file with various HTTP queries (different queries mean different content of course) for a JavaScript onload file that is dynamically created by PHP.

Try using this at the very top of the file and it may helpful to you!
