 According to the RFC specifications, an HTTP Method.OPTIONS request that contains content
 must have a Content-Type header. This method checks for the presence of the Content-Type header
 in such requests. It does not validate the actual value of the Content-Type header, as determining
 its validity would require knowledge of all valid media types, which is beyond the scope of this method.
 If the header is absent, a ProtocolException is thrown.
 
Note: This method does not check the validity of the Content-Type header value, only its presence.
