["Masakazu Kitajo (JIRA)" <ji...@apache.org>]

Masakazu Kitajo created TS-2902:
-----------------------------------

             Summary: Allow POST requests without a Content-Length header
                 Key: TS-2902
                 URL: https://issues.apache.org/jira/browse/TS-2902
             Project: Traffic Server
          Issue Type: Improvement
            Reporter: Masakazu Kitajo


I get "*400* Content Length Required" when user agents send a POST request that doesn't contain any body data without a Content-Length header.
(The header is omitted because the length is zero, I think)

According to RFC2730 Section 3.3.2, presence of Content-Length is not MUST.
http://tools.ietf.org/html/rfc7230#section-3.3.2
{quote}
A user agent SHOULD send a Content-Length in a request message when
   no Transfer-Encoding is sent and the request method defines a meaning
   for an enclosed payload body.
{quote}

Also according to section 3.3.3,  a server are allowed to reject similar request with 411 Length Required, but not *400*.
http://tools.ietf.org/html/rfc7230#section-3.3.2
{quote}
  A server MAY reject a request that contains a message body but not a
   Content-Length by responding with 411 (Length Required).
{quote}

Traffic Server should accept the requests, no body data without Content-Length header, or reject it with *411*. I think the former one is better for interoperability.
