sending HUGE file to client via Response.Binary Write

Zam
Hello World,

Under Windows 2003 Server. IIS6.

The following code working fine for small files, and for files with size
about few megabytes.

If I am trying to send HUGE file -- about 700 Megabyte -- w3wp.exe eat all
memory (I have 1024 megabytes) and all CPU time without positive result.

Question: how could i _clever_ and fast send very huge file to client, with
keeping "file location privacy" ?

<%
Response.Buffer = False
Server.ScriptTi meout = 30000

Response.Conten tType = "applicatio n/x-unknown"
fn = "movie1.avi "
FPath = "g:\movies\ " & fn
Response.AddHea der "Content-Disposition", "attachment ; filename=" & fn

Set adoStream = CreateObject("A DODB.Stream")
chunk = 2048
adoStream.Open( )
adoStream.Type = 1
adoStream.LoadF romFile(FPath)

iSz = adoStream.Size

Response.AddHea der "Content-Length", iSz

For i = 1 To iSz \ chunk
If Not Response.IsClie ntConnected Then Exit For
Response.Binary Write adoStream.Read( chunk)
Next

If iSz Mod chunk > 0 Then
If Response.IsClie ntConnected Then
Response.Binary Write objStream.Read( iSz Mod chunk)
End If
End If

adoStream.Close
Set adoStream = Nothing

Response.End
%>

With best regards,

Not familiar with streams so this is mostly a guess but you might try making
sure that the stream's "mode" is set to adModeRead (=1).

Hi. This is a feature that is really going on my nerves as I've been writing SOAP Web services using ASP and SOAP toolkit 3.0. My web services ASP scripts send XML data to the client application. When I'm debugging under Visual Sudio, IIS prefixes *all* streams that go to the client with <!-- METADATA TYPE="ASP_DEBUG_INFO">. I'm using XMLHTTP in some cases to receive data. Neither XMLHTTP v3 nor v4 seem to accept this as valid XML. I...

Hi, I really need you help because I'm not very familliar with ASP and I could not find any solution to my problem. To put you in situation, I have a CGI to which I send a file name, and that script return me that file. But for security reason, I don't want to publish the address of this CGI, so I encapsulated it in an ASP file. This way, only this ASP file knows where the CGI is.

Hi all, The following code was suggested by one of the users in this newsgroup when a pdf file was requested by a user from an asp page. I used the similar code in my page and the very interesting thing is when the pdf is displayed on the fly, the whole page is a gibberish code in stead of a normal pdf file. But it displays fine if I just use a link to a file on the page. Can you tell me what's the possible reason will cause this problem?...
