Clear Reports cache after running report

Question

Hi
Is there any way I can programmatically clear the reports cache on the 9iAS server once the report has been run ?
I am using web.show etc in my forms and would like to delete the report once I exit the form.
I have the jobid - but how does that relate to the physical file on the disk ?
Ideas anyone ?

I am having the same problem.
I manage a database with highly confidential data that has forced me to implement a Virtual private database (VPD) on Database 9i release 2.
Once users run their reports, copies are saved on the reports cache on Oracle9iAS. The reports in the cache can be viewed by anyone who knows the URL http://my9iASserver_name:7778/reports/rwservlet/getjobid1?server=myrepserver_name
without the need of authentication (username and password).
This negates the work I have done on the VPD, moreover everyone including the intenal auditors think that the system is bogus since a user can access information that does not belong to them without being restricted.
The solution I require is either to bypass the reports cache (or any other cache involeved including the web cache), or if this is impossible, then a program to delete any report as it hits the cache. So that at any given second, the reports cache is empty.
I am also aware that the minimum time you can schedule a task on the windows scheduler is 1 minute which is too much.
At this time, my focus is not the performance of the Oracle9iAS but its security and management does not care how slow it becomes as long as it is secure
Your help is appreciated
