/// @assertion bool autoUncompress
///  read / write
///  Get and set whether the body of a response will be automatically
///  uncompressed.
///
///  The body of an HTTP response can be compressed. In most situations providing
///  the un-compressed body is most convenient. Therefore the default behavior is
///  to un-compress the body. However in some situations (e.g. implementing a
///  transparent proxy) keeping the uncompressed stream is required.
///
///  NOTE: Headers in from the response is never modified. This means that when
///  automatic un-compression is turned on the value of the header Content-Length
///  will reflect the length of the original compressed body. Likewise the header
///  Content-Encoding will also have the original value indicating compression.
///
///  NOTE: Automatic un-compression is only performed if the Content-Encoding
///  header value is gzip.
///
///  This value affects all responses produced by this client after the value is
///  changed.
///  To disable, set to false.
///
///  Default is true.
/// @description Checks that is the value of this property is [false] then the
/// body of a response is not automatically uncompressed.
