> We have some users attempting to POST where the content length is -1.
> POST /services/rest HTTP/1.1\r\n
> Host: api.flickr.com\r\n
> Accept: */*\r\n
> Content-Length: -1\r\n
> Content-Type: application/x-www-form-urlencoded\r\n
> Expect: 100-continue\r\n
> ATS goes ahead with this request and connects to the origin and passes the invalid content length.  
> Preferable, and consistent with the spec, ATS should immediately respond to the client with an error.
> RFC-2616 Section 14.13 says 'Any Content-Length greater than or equal to zero is a valid value.'  I interpret that as a negative content length value is invalid.
> I propose that ATS respond with a '400 Invalid Request' for PUT/POST/PUSH requests when the user provided content-length is less than 0.
