Is SPCache a farm-wide cache?

Question

The MSDN documentation on the SPCache leaves very much to the imagination. But since it sounds interesting, I'm wondering whether it is a farm-wide cache. Does anyone know?

Currently I'm caching using the System.Web.Cache, but this makes flushing cache entries across the farm difficult, so a built-in farm-wide solution would be quite preferable.

Is the SPCache the same as the "object cache"?

@Kit Interesting, didn't see that. Curious that Michael thinks it is well documented. :) — ScarePoint, Apr 07 '11 at 06:17

Well, compared to the usual SharePoint documentation it's pretty well documented :)

I'm pretty sure it's not Farm Wide. Essentially it is a thread-safe Dictionary in memory of the server that uses it, and I have not seen anything that synchronizes it across the farm (I was planning to build my own object-cache for that purpose at some point).

Thanks. Guess I'll use shorter cache times instead of building something farm-wide. – ScarePoint Apr 07 '11 at 07:48

If you want a multi-server high performance cache consider using the AppFabric cache.

Agreed, Velocity also suppports claims based auth so it's quite easy to set up in a secure manner. – Wictor Wilen MCA MCM MVP Apr 09 '11 at 09:05
