can't open pdf file from aspx page

[graphicsxp]

Hi,
I have the following:
Dim p As String = Server.MapPath("~/Uploads/pdf/test.pdf")
Response.Redirect(p)

The value of p is correct and the file exists. If I enter manually the
value of p into my browser address bar, then the pdf file is properly
opened.

However from the code it doesn't work and although I've added a try
catch block I still can't see the exception. It says:


An exception of type 'System.Exception' occurred in myProject.DLL but
was not handled in user code.

I'm a bit lost there. Can you help ?
Thanks

Copied and pasted from a previous post by Karl:

Response.Redirect throws a ThreadAbordException
intentionally. Technically, Response.Redirect calls Response.End() which
throws the exception.

If you specify true as a 2nd parameter (by default it's false),
Response.End() isn't called, and the page is fully processed before being
redirected.

The real solution to your problem is not to swallow exceptions like you are
doing. You really shouldn't ever catch Exception.

Server.MapPath translates to a *local* (to the server) filepath. The
browser (of the remote user) shouldn't be able to find the file there.
And I don't think you can redirect to a local file, that's why you get
the error.

Get the Request.ApplicationPath ("/" for a root-app, (virtual)
directory without trailing "/" for a non-root app), and append your
"Uploads/pdf/test.pdf" to that for a correct redirect path.
