Stop caching of Reserved.ReportViewerWebControl.axd in temp folder while running the ssrs report.

Hi all,

i am working on asp.net, having a page with report viewer control on it. When ever report runs it downloads the temporary file in client pc. as below

I have web config with handler and httphandler like this.

<system.webServer>

<handlers>
      <add name="ReportViewerWebControlHandler" validate="false" preCondition="integratedMode" verb="*" path="Reserved.ReportViewerWebControl.axd" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=9.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A" />
    </handlers>

</system.webServer>

And

 <system.web> 

<add verb="*" path="Reserved.ReportViewerWebControl.axd" validate="false" type = "Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />

</system.web>

I need to stop the above file to cached in the "Temporary Internet Files" folder.

Any help would be appreciated.
