Is it possible to prevent user to edit parameters in adress bar?

I have reports in report server which are accessed by url access with parameters.

When the report is generated the whole url string is displayed in the adress bar with parameters. Is there any way to prevent the user to change the parameter value?

Any ider whould be very appreciated!

You could use a html form and use POST instead of using GET via the url.
