Chunked client POST support in ASP

The release notes for IIS 6.0 talks about ASP support for POSTs from clients
that are using chunked Transfer-encoding.
Does anyone know what this support means? It does not seem to be possible to
use Request.BinaryR ead, and Request.TotalBy tes returns -1.

Thanks

Hello,

For IIS 6.0 default insatllation, we need run a script command to enable
chunked transfer encoding:

cscript adsutil.vbs set /W3SVC/AspEnableChunke dEncoding "TRUE"

For detailed information on this, you may refer to:

http://support.microsoft.com/kb/278998

Luke, thanks for the reply!

I've tried setting the metabase property, but nothing changes.
Request.TotalBy tes is till -1.
From the Knowledgebase article I get the impression that this property
controls if the server is using chunked encoding when sending data, not how
client POST:s are handled.

Sincerely,
Jonas

Does this setting really apply to POSTs from a client? The text of the
article seems to discuss the transfer of output to the client.

Feb 6 '07 #4
Hello,

can you share some idea on how you submit the data from client? I may test
this on my side to see what had happened.

Sincerely,

Luke Zhang

Hi Luke!

The actual client that are causing problems is a Microsoft BizTalk server,
but for tests I use the command line client "curl", http://curl.haxx.se
With curl you can remove the "Content-length" header and add the
"Transfer-encoding: chunked" header, and send a file containing
chunked-encoded data according to the HTTP 1.1 spec.
For example, the string "abcdefghijklmn opqrstuvwxyz123 4567890abcdef" could
be encoded like this:

1a
abcdefghijklmno pqrstuvwxyz
10
1234567890abcde f
0

Hello,

Would you please let me know which version of curl you download and the
exact syntax you used? I may test it on my site to see I can get same
result.

Hi Luke!

I'm using curl version 7.16.0 (Win32)
The command line looks like this (the data file with the encoded data is
named chunk.txt)

curl -H "Content-length" -H "Transfer-encoding: chunked" --data-binary
@chunk.txt http://localhost/test.asp

Hello,

Thank you for the information. I download it from their web site and test
with an ASP page, it actually return -1. I also test it with an ASP.NET
page, it returns correct bytes length. Not sure if this is an issue of curl
or asp.

Hello,

Good that you're able to reproduce the behaviour. As I wrote before, the
real problem is caused by a MS BizTalk server that is posting chunked data to
the IIS. This makes me pretty sure that this has nothing to do with curl,
it's an issue with ASP.
