PHP Sessions not working on XP

[timbr8ks]

Boy do I need help.

I'm heading to a tradeshow, where I'm going to show a software product. It's a Web based product built in PHP and MySQL. The Internet connection is way too expensive (something like $800/day), so I'm demonstrating the product on my laptop. No big deal, I've done it a thousand times.

But suddenly my laptop doesn't pass session data from one page to the next. The exact same code works fine on my desktop computer and on line, but on my laptop it no longer passes session data.

I'm running XP Pro, PHP 4.3, and MySQL 4.0. This all worked fine yesterday. Today it does not. I cannot think of anything that's changed on my computer.

Can anyone make any suggestions?

Thanks in advance.

Perhaps clearing your TMP file directory? Could be that it got too large....

Nope. That wasn't it. I've cleared my cache, I've done a disk cleansing, restarted 600 times ... no good. Using print_r($_SESSION), I can see that the session variables are being created, but they're not being passsed to the next page.

Ugh.

Okay, so now the obvious question:
What does your code look like?

You said you didn't do anything, but just to be sure, let's see some code. That's the only thing I can think of that would cause this issue.
