Hello everyone!

I would like to be able to do the following things, using the asp.net cache:
1. Setup different cache regions, and assign classes/collections to the appropriate regions
2. Have cached data expire after a fixed amount of time since being added in the cache, regardless of the last access time (as opposed to sliding expiration, a fixed amount of time from the last access)

For issue 1, it looks like jcs-class-cache/jcs-collection-cache are not implemented. They are not even read from the config file.

For issue 2, IMHO the current interpretation of staticExpiration is of not much help. I cannot see a scenario where I would want to expire cached data at a predetermined date/time. Is my understanding of the current mechanism wrong?

Is there any way to do it with nhibernate 1.0?
For issue 2 I can volunteer, however, issue 1 may have more implications and I don't have the time right now to see it completed.

Thanks,
Cris

The regions are configurable already. Please see the unit test code for samples. Sorry for the lack of "proper" documentation.

The expiration issue is a known issue and up for discussion. See this thread: http://nhibernate.sourceforge.net/forum/viewtopic.php?t=1015

The the caching tags are "cache" or "jcs-cache" ("jcs-cache" should go away soon), and is the same for both the class level and the collection level.


I agree totally. I don't know what Microsoft was thinking. What developer would ever say "I want the data for my web page to expire on the third Wednesday in July, 2037." - it's rediculous.

Yeah, I already figured out how to configure the regions in SysCache.
There is no way to attach classes/collections to regions though, or at least I wasn't able to find it.

Thanks,
Cris

I believe the region is the object namespace. What do your logs look like?

By looking at the logs, I can see the region name is the type full name.
This is a little too fine grained for a reasonably sized applications.

Do you know if there are any plans to add support for <jcs-class-cache/> element in the hibernate.cfg.xml file?

Thanks
Cris

<jcs-cache> and <cache> elements will be supported in 1.0.1.

Great! I suppose you are hard at work. When do you plan on releasing 1.0.1?

Thanks,
Cris

Very soon, this week or next week.

Why are we hanging on to "jcs-" in the all the cache settings? It's legacy in Hibernate for Java, and there is no JCS Cache for .NET.
