I need someone's help on this Javascript
 

Okay Guys,

Here is the query.

I am having my forum on vbulletin & I am trying to run a javascript on the showthread page.
All i want is that the javascript should execute only ONCE per user session & should repeat itself in sometime like 7 days or so.

What can be done..??
I need some kind of COOKIE solution for this..!!

Help me on this.
Regards

Javascript has full access to document cookies. Here's an articles about cookies and Javascript:

You can set the cookie in your script, and do a conditional too see if the browser has a valid, unexpired cookie before evaluating the rest of the code.

You have to be careful though because cookies aren't that reliable; for instance if the user uses a different browser the code will run.
