/**
* Represents a parsed Trailer HTTP response header.

*
* The Trailer general field value indicates that the given set of header fields is present in the trailer of a message
* encoded with chunked transfer coding.
*
*
Example
*
* Trailer: Max-Forwards
*
*
* RFC2616 Specification
*
* The Trailer general field value indicates that the given set of header fields is present in the trailer of a message
* encoded with chunked transfer-coding.
*
*
* Trailer = "Trailer" ":" 1#field-name
*
*
*
* An HTTP/1.1 message SHOULD include a Trailer header field in a message using chunked transfer-coding with a non-empty
* trailer.
* Doing so allows the recipient to know which header fields to expect in the trailer.
*
*
* If no Trailer header field is present, the trailer SHOULD NOT include any header fields.
* See section 3.6.1 for restrictions on the use of trailer fields in a "chunked" transfer-coding.
*
*
* Message header fields listed in the Trailer header field MUST NOT include the following header fields:
*
* - Transfer-Encoding
*
- Content-Length
*
- Trailer
*
*
* Additional Information
