cache outbound requests, but not inbound - 4.Oct.2006 3:46:17 PM

Hi folks,

I've got cache enabled on my ISA 2004 server. But I'm having troubles with the rules. We've got 3 legs, internal, DMZ, external. I've been requested to disable cache for inbound (external to DMZ, and internal to DMZ) requests, but to leave it enabled for outbound (internal to external).

The reason for disabling inbound traffic is so log analyzers can accurately show what is happening on our log servers (how many hits, etc.).

How do I set up the cache rules to do this?

Mark

Create Cache Rules that reference the published server (whatever is specified on the "To" tab of the rule. I create a "URL Set" for each published server and include that in a Cache Rule.

Specifically, go to Firewall Policy\Toolbox\Network Objects\New - URL set
Name - %PublishedServer% - No Cache
Add - http://%internal.server.name%

Then go to Configuration\Cache\Tasks\Create a Cache Rule
Name - %WebPublishingRule% - No Cache
Add - URL Set - %PublishedServer% - No Cache from earlier
Retrieve the requested object.. - "Only if a valid version of the object..."
Select When content should be stored in the cache - "Never, no content will ever be cached"
Continue to "Next" through this wizard until it's finished.

After that, you're set - you might have to download/install CACHEDIR from MSFT's site and delete everything from cache to get the rule to take effect.

I really really really really really wish there was an option in the Web Publishing Rule to "Create Corresponding No Cache Rule" or some such option - that'd be sweet. It's admittedly an obscure option, but hey, I can dream right?
