Does the HTTP request contain body content?

"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 message-headers."
https://www.w3.org/Protocols/rfc2616/rfc2616-sec4.html#sec4.3

However, some browsers send a Content-Length header with an empty string for e.g. GET requests
without any message-body. Therefore rather than checking for the existence of a Content-Length
header, we will allow an empty value to indicate that the request does not contain body.
