The RFC states that "the sender SHOULD generate a Trailer header," suggesting it is not mandatory. If I proxy an back end service that provides a streamed response, the AWS gateway returns a content-length header in the response instead - this implies the amazon API gateway is buffering the stream from the backend and then returning the … In CTE, each chunk is preceded by its size in bytes. This behaviour can be modified by setting a chunked encoding policy e.g.. Soon I have found that it is the problem of RetryableOutputStream, and the fix is to add header "Transfer-Encoding: chunked" to the request. Nov 23 '11 at 17:43.

The data to transmit will be split in chunks. 2.If a Transfer-Encoding header field (section 14.41) is present and has any value other than "identity", then the transfer-length is defined by use of the "chunked" transfer-coding (section 3.6), unless the message is terminated by closing the connection. Message Trailers.

You can send data in fixed size or variable size chunks. If you want to compress data over the whole connection, use the end-to-end Content-Encoding header instead. To give you a general idea, the HTTP implementations on many mobile handsets will decide to use a chunked transfer encoding if the payload of a PUT/POST request is over an arbitrary threshold. CF> Regards. This code will still have the "Transfer-Encoding: chunked" header. Transfer-Encoding: chunked? Most simple way is download to memory and stored as BASE64 encoded string, this is handy when the response data is small. I can set this header but how to set “chunked” body ?
