[SOLVED] ASP.NET how to return pdf file as response without changing response header


I want to return a pdf file as response to some button click.
I succeeded to send the pdf file, but when i try to save it via the browser, it won’t let me save it as a .pdf file (but as .aspx file)

here’s the code:

Dim myWebClient As WebClient = New WebClient()
Dim myDataBuffer As Byte() = myWebClient.DownloadData(LocalImageURL) ' LocalImageURL is some path to a pdf file
Response.ContentType = "application/pdf"



if I am adding also the following line before writing the byte array:

Response.AddHeader("content-disposition", "attachment;filename=report.pdf")

it does the trick, but the problem is that the page remains stuck (looks like it still waits for server response to come)
