Cache not working - SQL Server Source

[HighKeys]

Hi there,

i configured the Cache for the Datasource to 8 hours, and opened a test report, if i directly open the same report with the same user and same settings again, i still can see the query to the SQL Server. When i dump the Cache state in the Administration the log file stays emtpy.

I'm wondering if I miss something or isn't the cache working with MS SQL Server as data source.

Thanks for your help.
