Hi,
I'm having some trouble with the kendo report configuration.

My reports run perfectly on localhost, but when i deploy my application the reports fail to load. After some investigation i realised that it is an issue related with permissions asi get the following exception : "Access to the path 'C:\Windows\TEMP\Html5App\10.2.16.1025\LCT\value.dat' is denied."

I have looked at the documentation and at similar questions such as this one (http://www.telerik.com/forums/cache-file-error-not-fixed-with-config-entry), and  tried different configurations but unfortunately still did not manage to overcome the issue. 

I know this issue is related to cache configuration, i read the documentation carefully, and this page (http://docs.telerik.com/reporting/using-telerik-reporting-in-applications-rest-service-cache-management-overview) sugests that cache management is mandatory.  However on the documentation its not clear why?  Also is not clear  what is actually being cached?? Is it a compiled version of the report template which recieves parameters and dysplay the data,  or is it  the actual final report which is displayed? 

Because if it is the later then is s there a way i can publish my reports without caching? Because i cannot have a cached instance of each invoice which is displayed and printed only once. And is not really advantageous for me as most of the reports will rarely will be called twice with the same parameters

Hi Carlos,

The cache settings of the Reporting REST Service that handles requests by HTML5 Viewers is mandatory. For more details about the cache and how it works, please check Cache Management.

About the error message, it indicates a lack of read/write permissions to the cache storage set via FileStorage in your case - Access to the path 'xxxxxx\value.dat' is denied..


Let us know if you need further help.

Regards,
Stef
