* According to RFC2616 #4.4, amended by the HTTPbis working group,
* the presence of a message-body in a REQUEST and its transfer length
* must be determined that way (in order of precedence) :
* 1. The presence of a message-body in a request is signaled by the
* inclusion of a Content-Length or Transfer-Encoding header field
* in the request's header fields. When a request message contains
* both a message-body of non-zero length and a method that does
* not define any semantics for that request message-body, then an
* origin server SHOULD either ignore the message-body or respond
* with an appropriate error message (e.g., 413). A proxy or
* gateway, when presented the same request, SHOULD either forward
* the request inbound with the message- body or ignore the
* message-body when determining a response.
*
* 2. If a Transfer-Encoding header field (Section 9.7) is present
* and the "chunked" transfer-coding (Section 6.2) is used, the
* transfer-length is defined by the use of this transfer-coding.
* If a Transfer-Encoding header field is present and the "chunked"
* transfer-coding is not present, the transfer-length is defined
* by the sender closing the connection.
*
* 3. If a Content-Length header field is present, its decimal value in
* OCTETs represents both the entity-length and the transfer-length.
* If a message is received with both a Transfer-Encoding header
* field and a Content-Length header field, the latter MUST be ignored.
*
* 4. By the server closing the connection. (Closing the connection
* cannot be used to indicate the end of a request body, since that
* would leave no possibility for the server to send back a response.)
*
* Whenever a transfer-coding is applied to a message-body, the set of
* transfer-codings MUST include "chunked", unless the message indicates
* it is terminated by closing the connection. When the "chunked"
* transfer-coding is used, it MUST be the last transfer-coding applied
* to the message-body.

* All responses to the HEAD request method MUST NOT include a
* message-body, even though the presence of entity-header fields
* might lead one to believe they do. All 1xx (informational), 204
* (No Content), and 304 (Not Modified) responses MUST NOT include a
* message-body. All other responses do include a message-body,
* although it MAY be of zero length.
*
* 1. Any response which "MUST NOT" include a message-body (such as the
* 1xx, 204 and 304 responses and any response to a HEAD request) is
* always terminated by the first empty line after the header fields,
* regardless of the entity-header fields present in the message.
*
* 2. If a Transfer-Encoding header field (Section 9.7) is present and
* the "chunked" transfer-coding (Section 6.2) is used, the
* transfer-length is defined by the use of this transfer-coding.
* If a Transfer-Encoding header field is present and the "chunked"
* transfer-coding is not present, the transfer-length is defined by
* the sender closing the connection.
*
* 3. If a Content-Length header field is present, its decimal value in
* OCTETs represents both the entity-length and the transfer-length.
* If a message is received with both a Transfer-Encoding header
* field and a Content-Length header field, the latter MUST be ignored.
*
* 4. If the message uses the media type "multipart/byteranges", and
* the transfer-length is not otherwise specified, then this self-
* delimiting media type defines the transfer-length. This media
* type MUST NOT be used unless the sender knows that the recipient
* can parse it; the presence in a request of a Range header with
* multiple byte-range specifiers from a 1.1 client implies that the
* client can parse multipart/byteranges responses.
*
* 5. By the server closing the connection.

* the RFC explicitly allows spaces before it, and not within the

* after the equal sign too, resulting in some (rare) buggy
* implementations trying to do that. So let's do what servers do.
* Latest ietf draft forbids spaces all around. Also, earlier RFCs
* allowed quoted strings in values, with any possible character
* after a backslash, including control chars and delimitors, which
* causes parsing to become ambiguous. Browsers also allow spaces
* within values even without quotes.
*
* We have to keep multiple pointers in order to support cookie
* removal at the beginning, middle or end of header without
* corrupting the header. All of these headers are valid :
*
* Cookie:NAME1=VALUE1;NAME2=VALUE2;NAME3=VALUE3\r\n
* Cookie:NAME1=VALUE1;NAME2_ONLY ;NAME3=VALUE3\r\n
