TE
The transfer codings the user agent is willing to accept.
Fastly reads this header from requests and writes it into requests. It is defined by an external standard.
PROTECTED: This header cannot be modified in VCL.
TheTE header field in a request indicates what transfer codings, besides chunked, the client is willing to accept in response, and whether or not the client is willing to accept trailer fields in a chunked transfer coding.
TheTE field-value consists of a comma-separated list of transfer coding names, each allowing for optional parameters (as described inSection 4 of RFC 7230), and/or the keywordtrailers. A client MUST NOT send the chunked transfer coding name inTE; chunked is always acceptable for HTTP/1.1 recipients.
