Need suggestion on URL Rewrite.....

I have to do an module program which downloads pdf files in the client side. Currently, when users download the file, the url of the downloaded file is viewed by the user.

Modification instructed:
1. In the page where the file download is requested, the url of the downloaded file is viewed in the status bar of that web page. Modification is that the status bar should not display the url of the downloaded file. -- This had been corrected and the code has modified accordingly. It is done correctly only for the first page. Blinks how to process this for the second page..

2. Currently, the call for the download page is given along with the filename of the user request. The filename is passed as the querystring. Modification needed is that the url should get rewritten as "~/download.aspx" instead of "~/download.aspx?".

I came across using "urlrewriter". But don't know how to implement since i feel little confused with the code examples in net.

I'm placing my code for ur assistance. I'm not using webconfig file also.

this.RegisterStartupScript("SetStatusText", "<script>window.status='" + strMessage + "';</script>");

if (Request.QueryString.Count > 0)

string fn = Request.QueryString.Get(0).ToString();

string spath = @"~\pdf\" + fn + ".pdf";
Response.ClearContent();
Response.ClearHeaders();
Response.ContentType = "application/pdf";
//Response.ContentType = "application/octet-stream";
Response.AddHeader("Content-Disposition", "attachment; filename=my_test.pdf");

Response.TransmitFile(spath);
Response.End();
}

}
}

Even using register startup variable, in Old_download_pdf.aspx, it is showing the downloaded file url path in status bar of the page Old_download_pdf.aspx. Also we have to rewrite the url from "~/Old download_pdf.aspx?fn=" as simply "~/Old download_pdf.aspx".

When i tried using a hidden variable, i failed in setting the value of the hidden field during the click event of the dynamically creating hyperlink control.

How to complete this? Thanks in advance.
