Crap, Forgot that SSRS 08 doesn't rely on IIS to host report manager and virtual dirs. Any other ideas?

Was hoping to do this on-demand when it is clicked from the application. The report is an invoice and I would rather not give the users the ability to export to word or excel for editing. Currently I have an IIS site for sharepoint(SSL) then a separate one for SSRS(http), causing a second auth by users, if they access http://servername/reportserver. I guess an alternative is to have the SSRS virutal dirs inside the same IIS application site. Thoughts?

Correct me if I am wrong in understanding your requirement , Have you tried data driven subscriptions which will export rdl into PDF or excel format to Sharepoint site, instead of passing URL. Below link will provide some more info http://technet.microsoft.com/en-us/library/bb283186.aspxNanda

Running SSRS SQL 2008 with SharePoint 2007 in Integration mode. I want to pass a URL parameter to the RSViewerPage.aspx in SharePoint site to export the rdl to PDF or XLS automatically. I was able to pull off going directly to the reportsever URL, but would like to do the same with SharePoint site. Any ideas? Thanks in Advance.
