/// Accept Request Header
/// The Accept request-header field can be used to specify certain media types which are 
/// acceptable for the response. Accept headers can be used to indicate that the request 
/// is specifically limited to a small set of desired types, as in the case of a request 
/// for an in-line image.

/// 
/// Accept-Charset Request Header
/// The Accept-Charset request-header field can be used to indicate what character sets

/// Content-Encoding Header
/// The Content-Encoding entity-header field is used as a modifier to the media-type. 
/// When present, its value indicates what additional content codings have been applied 
/// to the entity-body, and thus what decoding mechanisms must be applied in order to 
/// obtain the media-type referenced by the Content-Type header field. Content-Encoding 
/// is primarily used to allow a document to be compressed without losing the identity 
/// of its underlying media type.
