The anti-leeching can be done using URL rewrite (which is installed with ARR). tip #6 http://ruslany.net/2009/04/10-url-rewriting-tips-and-tricks/

Jim You are absolutely right. We did change the default setting from 5 to 60 seconds. We made this change with the CDN customers in mind where 5 second caching was simply too short (ie. Publicly available Internet contents that are cache-able don't really change every 5 seconds. And by keeping it...

I would like to understand how ARR disk caching works with ASP.Net applications and have not been able to find a good reference. I have a simple testing server farm configuration with a single ARR server and a few content servers. Everything with my ASP.Net application is caching appropriately, static...

With memory (and in conjuction with disk), it works slightly differently. Let me see if I can clarify. Let's suppose that the memory cache interval is set to 5 seconds (default value.) The flow would be something like: 1) Request is received by Windows server (http.sys, actually). 2) Cache miss at...

Won, Thanks that was great. To carry over an idea from our other thread ( http://forums.iis.net/t/1160295.aspx ) I assume that irrespective of whether the object is cached in memory or disk, the object invalidation process with be the same. The cached object will always be served to the requesting user...

I assume the prescribed solution for this condition, might be create a Global URL rewrite rule on the ARR server that redirects input for a blank URL explicitly to the default page. If that rule processes before the ARR Cache Control rule then I would think you would get the same behaviour for the default...

Jim The memory cache is done at the kernel level. You could have a netmon between ARR and the content server to see if you actually see the cache hit. A simpler way would be to type the following on an elevated command prompt (which will show you what's stored in kernel cache.) netsh http show cache...

Won, Thanks again for the quick post back. I have a following questions regarding Farm level statistics and the Memory Cache Duration setting on the Caching form on the Server farm features menu. I have tried a few different settings for Memory Cache duration, but have not been able to see is a request...

Jim You are right again, but here is more lengthy explanation. The fact that http://target/ shows the default.htm is due to how the default page configuration is setup on the origin server. However, the URL that is going through ARR is still http://target/ (and not http://target/default.htm ). ARR, like...

Won, Thanks for the speedy reply. I think I solved my mystery regarding the Cache Control Rules and now I have another question. First, I did not mention that I happened to be testing with defauft page, Default.htm. I was typing http://(target)/ as my URL. When I did this the page was cached. Then I...
