Using chunked encoding in a POST request to an asmx web service on IIS 6 generates a 404

Question

Hi, I'm using a CXF client to communicate with a .net web service running on IIS 6. This request (anonymised):

POST /EngineWebService_v1/EngineWebService_v1.asmx HTTP/1.1
Content-Type: text/xml; charset=UTF-8
SOAPAction: "http://.../Report"
Accept: */*
User-Agent: Apache CXF 2.2.5
Cache-Control: no-cache
Pragma: no-cache
Host: uat9.gtios.net
Connection: keep-alive
Transfer-Encoding: chunked

followed by 7 chunks of 4089 bytes and one of 369 bytes, generates the following output after the first chunk has been sent:

HTTP/1.1 404 Not Found
Content-Length: 103
Date: Wed, 10 Feb 2010 13:00:08 GMT
Connection: Keep-Alive
Content-Type: text/html

Anyone know how to get IIS to accept chunked input for a POST?

Thanks

Chunked encoding should be enabled by default. You can check your setting with:

C:\Inetpub\AdminScripts>cscript adsutil.vbs get /W3SVC/AspEnableChunkedEncoding

The 404 makes me wonder if it's really a problem with the chunked encoding. Did you triple-check the URL?
