I'm dealing with RSS feeds predominately. Whilst I would like to use 
Caching as much as possible, I have unfortunately run into the problem 
of knowing that a feed has been updated (ie, I opened it in Firefox) 
though unable to see the updated feed in my app.

If you know of a better way to handle this, it would be much 
appreciated.

The way in which I'm getting the rss feeds is by calling

NSXMLDocument initWithContentsOfURL: options: error:

Any and all help is much appreciated.

Thanks,
