Every now and again you run into silly (but useful) sites with silly (and useless) session timeouts with no means of changing them. So you do something else while working with the sites only to come back and find out you’ve been logged out.
Well, here’s a little script to help with this situation:
Just set your preferred interval in seconds. This hack is particularly nice IMHO in that it even lets you set a list of partial URLs the pages to be reloaded should contain. Also, it checks System Events to make sure we’re not actually in Safari. Just don’t forget to switch to another app for this to work. ;)
Oh, and the on idle stuff only works if you save it as an application and check “Stay Open”.
