"Response.Buffer=false" broken in IIS6?

Thanks,

I tried deactivating "enable buffering" at web site level, but there still
is some buffering taking place before the data is actually sent....

It looks as if some other layer is buffering the output.

Our app used to run (with functional "Response.Buffer=false") on
Win2000/IIS5.

The problem appears when migrating to Win2003/IIS6.

So could the problem be at Win2003 level rather than IIS6 level??

Many thanks for any advise....

Antoine Sartoretti.

Sure,
Try to enable buffering then, and set the buffering limit to 1.

see AspBufferingLimit

Forgot to add, you need the metabase explorer for IIS6 to edit / add this
item.

Besides, this script below works like a charm on my IIS6 and I migrated from
2000 as well.
file: testbuffer.asp
<%
Dim cn
Response.Buffer = False
Set cn = Createobject("ADODB.Connection")
cn.Open "provider=sqloledb;integrated security=sspi"
cn.Execute "waitfor delay '000:00:1'",,128
Response.Write "1"

cn.Execute "waitfor delay '000:00:5'",,128

Response.Write "2"

cn.execute "waitfor delay '000:00:5'",,128
Response.Write "3"
cn.Close
%>

This is ASP.DLL related.

Ok,
You are absolutely right.
"Response.Buffer=false" does work.
I now realize my problem is related to _the way it works on IIS6_, different
from IIS5...
The issue is this:
=> we used "Response.Buffer=false" in order to be able to evaluate web
clients bandwidths.
=> we relied on the fact that "Response.Write(big chunk of data)" was a
"synchronous" operation when buffering was off on IIS5 (ie will not return
till the data is actually sent)
=> it _seems_ that on IIS6, with buffering disabled, "Response.Write(big
chunk of data)" is still asynchronous....
That change in behavior we did not anticipate...
Hence the possibility of some other entity on the server doing some sort
"mild buffering" before actually sending the data (?)
I'll investigate.. Any advice on the subject still more than welcome.
Thanks a lot for your time and help.

I understand you.
Did you try Response.BinaryWrite as well? (give it a byte array which comes
from a ADODB.Stream object )...

I will ask the ASP developer about the behavior.

 >> Stay informed about: &quot;Response.Buffer=false&quot; broken in IIS6? 

Hello,

I can confirm that ASP was changed in IIS 6 from synchronous to asynchronous
I/O when sending data to the client. This change was done for performance
reasons.

There is no way to get ASP to do synchronous sends in IIS 6. If you want
that fine of control over the response, you would need to use an ISAPI
extension. Note that even in the case of synchronous sends, it is not
necessarily possible to determine the client bandwidth from an application
on IIS. For example, if you were to do a 1K send, there is a strong
