Hi Thom,
Thanks for your response.
So since the file is on remote site, if you directly redirect the client to
that server's url, the security restriction of the site on client will be
different from your local site which will also cause the unexpected
problem.... Is that remote server in your own local environment (domain
or subnet...) or can you use Remote File Share(like
\\servername\shareddir\......) to visit those files instead of HTTP url
link? As I mentioned before, use the code programmatically write out file
stream we can retrieve file from different source (database, local file,
remote file share ...... ). So if possible, you can consider put those
remote files in a remote file share so that our asp.net application can
read remote file share to retrieve the file stream and write to client...
Also, we can also consider just programmatically copy those file to local
first and write out the files from local disk place.....
How do you think ?

Steven Cheng

| I tried the approach that you suggested ...
|
| Unfortunately the way I was doing it allowed me to download the files
from a
| server different from the server with the ASP.NET code. Your approach
| requires the files to be on the same server.
|
| Conversely ... your approach works correctly for both .msi and .zip on
four
| systems running Windows Server 2003, Windows XP, and Windows 2000.
|
| Some Bits!
|
| I will live with the restriction.
|
| Mine is ...
|
| Response.Clear( );
| Response.ClearContent( );
| Response.ContentType = "application/octet-stream" ;
| Response.AddHeader("content-disposition", "attachment; filename=" +
| strURL );
| Response.WriteFile( Server.MapPath( "./" + strURL ) );
| Response.End( );
|
| Thanks for the help.
