Fix for ajax periodicalUpdate

[Christofer Dutz <ma...@c-ware.de>]

Hi,

I had some big trouble with the Internet-Explorer and periodical updates.
The Internet-Explorer didnt really send the requests to the sever, but 
answered them from it's cache.
Everytime the cache was manually cleared a real update was made, but 
only once.
The following modifications made periodicalUpdates work.

Hope this helps someone.

Chris
