Remove Session ID from reposted form data

[rwfresh]

Hi All,

I am using sessions on my site. I have certain forms with text fields that have URL's in them. Everything is fine until i repost the data back into the form. When i do this the URL's in the text fields end up with session ID's appended onto them. Any ideas on how to eliminate this?

at the last page try to use
session_unset("yourvariable")
or
unset("yourvaribale')
then
session_destroy();

I think more easy strip SID from data.
Like this:

$url=preg_replace('/&?SID=[0-9a-f]+/i','',$data);
