Delayed cookie update time

[Tyger]

I find that if I create a cookie or update an existing one it takes a little while for the information to be updated. That is: if I have one program which stores a value in an existing cookie, and then another program is run automatically which reads the cookie information, it will read the old value.

This is quite annoying because it means I must send the same data that the cookie should contain, to the second program because I cannot rely on it to read the correct information for itself.

If the second program is not run immediately, ie: there is a delay, then the cookie contains the value it should. It seems that it takes a little while for the new value to be stored.

This happens when I test programs both online, and locally. Is this a common problem, or am I doing something wrong?

The reason you're seeing this is because the cookie is a file on the user's system that needs to be saved. While the information is technically there, it takes a little time (more than your program takes to move on) to perminently resave the cookie to that file.

The way I've gotten around similar situations is once I write the information, I use the following line:

sleep 2;

This allows the user's system 2 seconds to resave the information. Change the number to anything you'd like, but usually 2 seconds is plenty of time to do this as I've seen.
