ISA 2004 SP2 - a caching question...

Hi All,
I've got ISA 2004 installed on a SBS 2003 SP1 domain.  Of course, SBS uses SharePoint.  One of the webparts available to SharePoint is the Weather "weather".  It shows the current temp and other conditions.  I noticed that I'm apparently looking at a cached version of the weather as at 11:46 pm at night in Tennessee, it is 94 degrees outside in the blistering moonlight.  (It gets hot here, but not that hot at night!).

Question:  how can I *not* cache certon URLs or is that even the best or valid approach to solving the temperature mis-reporting as described above?

Thanks,
Terry

Hello Terry. Two things strike me straightaway.

The first, it would be worthwhile posting a 'pointer question' in the Microsoft Sharepoint Topic Area for 20 points and inserting the URL for this question so the Sharepoint guys can have a look at well.

Secondly, lets have a look at caching on its own first.
Open the ISA GUI, select configuration - cache.
Open the toolbox window on the far right; if its closed, there is a grab handle half way dsown the right edge. Just click it and this togglkes the pane open and closed.
Can you confirm that caching is enabled? By default the refresh should be set to medium.
Have you enabled Active Caching?

Have you set up a Scheduled Content Download?
If you select the scheduled download, you will be prompted to accept some automatic changes to the policy.
Once done, you can set up a daily download and also set the repeat.  ie Run daily and repeat every 30 minutes (throughout the day)
Next, you can enter in the URL and whether to follow external links or the depth of links you want.
Lastly, con configure thinhs such as the TTL (Time to Live) etc.

Regards
keith

Caching is enabled.  The refresh is set to medium.  I cannot find a reference to the term "active caching" on the task pane on either Cache Rules or Content Download Jobs tabs.

I did enable the Schedulded Content Download.  I created one job and provided it the url that is actually used to retrieve the settings for that sharepoint 'webpart'; not the entire msn.com.

The Active Caching is the second tab along under the content download section.
