hey everybody, I'm with the following problem: my PHP scripts takes a very long time to execute (about 3 hours) because it has has system call to a perl script that is very time consuming. in IE (haven't noticed this in Mozilla or Konqueror) the execution of the PHP script doesn't finish, due to session expiry I think. I've searched on the net and I've found some PHP functions, like set_time_limit, but all of them DON'T consider external time, like I/O time or a system call time. So increasing this time wouldn't help me. Can anyone help?
