Reporting Q2 2011 new caching feature questions

[Jacob]

I'm trying out the new Q2 2011 version 5.1.11.713 features.
I keep reading the "Whats new" section and I'm seeing talk about these new caching features; however I am a little confused.

Does caching only work when using the WCF Reporter Service Implementation?
Can I use the caching features with the standard ASP.net web viewer control?
Will caching work in an out of proc session state set up?

I've been searching through documentation and i can't seem to find hardly any on these subject. 

My reports are larger reports and are throwing out of memory exceptions when running in out of proc session (web farm).
I've read numerous forum post on these issue and have read the design considerations. 
Just wanted to look into the caching options to maybe reduce these errors, but i can't find any documentation or guide on the caching topics.
I would like some more information if anyone could help. 
Any information regarding caching or memory exceptions would be great.

Hi Jacob,

Web Report Viewer is optimized in Q2 2011 release. However currently when the out-proc session state is used the caching mechanisms will not work.  We are still working on performance and memory optimization and one of the goals is to improve the web report viewer in out-proc session state. 

For general tips check out the Performance Considerations KB.

Kind regards,

In an in-proc state, how does the caching work?
Where is the data cached to?

Hi Jacob,

For in-proc we are caching the report viewers' streams on HDD and when the session expires the streams are deleted. 

All the best,
