Transfer-coding: Chunked calls 404 The system cannot find the specified file

I am trying to publish a page served by IIS6 and add the following header:

Transfer-Encoding: chunked

When I do this, I get 404 error: The system cannot find the file specified. . If I make the same request on a page without this header, it definitely exists.

Here are the headers - the only difference between the two requests is the snippet ...

 POST http://hostname/appname/index.html HTTP/1.1 Host: hostname Connection: keep-alive Transfer-Encoding: chunked Cache-Control: max-age=0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.31 (KHTML, like Gecko) Chrome/26.0.1410.64 Safari/537.31 Content-Type: application/x-www-form-urlencoded Referer: http://referrer/

And the body:

 4 xxxx 0

The IIS metabase has AspEnableChunkedEncoding set to true at the W3SVC level, and it is not redefined at the site level.

Why am I getting 404 error?

Update: I noticed in response to a failed request that:

 x-powered-by: asp.net

... no title. I do not know if this helps - it is, if I do not set a title in the request.

Is URLScan installed? It could be a title lock
