Hi,

I have the follow VB.NET code in a ASP.NET page to show PDF files.

            With Response
                .RedirectLocation = "PDF"
                .Clear()
                .ClearHeaders()
                .ContentType = "application/pdf"
                .WriteFile({COMPLETE FILE NAME PATH})
                .Flush()
                .Close()
            End With

Open in new window


It work fine in the first time that I select a PDF file. But when I select a PDF file that has already been shown before, do not load it again, remains to be shown the last PDF file loaded.

How can I fix this bug?

Thanks in advance, Camarate

Can you try these please:

.AddHeader("Pragma", "no-cache");
.CacheControl = "no-cache";
.Cache.SetCacheability(HttpCacheability.NoCache)
