Something weird with sessions

[Betty Perea]

I'm having a little weird condition.
I have a simple form (POST method), whose Action is a validation
script, most of the times it works. But sometimes, the validation
script does not "receive" the variables from the form script.
The code is very simple, so I think I should review some of the
parameters of the PHP version (4.3.4) installed in the server where my
site is hosted, but I'm not sure which of them I should check.
Does somebody have any idea of what it could be happening?
Thanks.

Maybe someone is playing with your form and sending different variables?
Maybe hoping to catch a vulnerability due to register_global s or just
having fun?

Thank you Pedro. The thing is that I'm testing the site by myself,
before I put it on production. Well, I will release it, and I'll keep
searching. If I get something, I'll let you know. Oh!, the
register_global s is "off".

Hi Betty,

I've solved a similar problem by calling session_write_c lose() explicitly
after updating the session var.
