Hibernate version: 1.2.1.400

Hello

I am hosting many instances of the same ASP.NET application on the web server, and I need 2-nd level cache solution.

Tried SysCache but it consumed far too much server memory than I can spend on this, I started to get OutOfMemory exceptions.

Now I am trying to set up MemCache on separate machine. I configured two test instances to connect to MemCache server. And - surprise - they started to "cross-load" the objects , resulting in total mess (one application loaded objects from second instance and vice versa). After setting up log4net I discovered that MemCacheProvider does not distingush instances, eg. :



Two instances use the same cache key, so it is possible that one application gets objects from second application's database :(
Because documentation of MemCacheProvider is very .... short, I ask you for help - is there any way to make separate "space" or something , one for every instance/database ? Running many memcache processes is not a solution , because I have over 50 application instances and there will be more in future.

Thanks in advance.

Newermind, problem solved.

Again I see the best documentation is the source code ;) There is "regionPrefix" property to distinguish application instances, just needed to put it at nhibernate configuration section :

FYI, here's a problem I had with cache regions and expirations.

I have read your post before, I don't need different expiration times so far, thanks for the warning anyway :)
