public Class HttpAttachments

If the value true is attached to the exchange under this key then Undertow will assume that the underlying application has already taken care of chunking, and will not attempt to add its own chunk markers. This will only take effect if the application has explicitly set the Transfer-Encoding: chunked header.

Attachment key for request trailers when using chunked encoding. When the request is parsed the trailers will be attached under this key.

Attachment key for a supplier response trailers. If a header map is attached under this key then the contents will be written out at the end of the chunked request or HTTP/2 response. Note that the results of RESPONSE_TRAILERS and RESPONSE_TRAILER_SUPPLIER will be merged if both exit with the value supplied by the supplier taking precedence. Note that if pre chunked streams are being used then the trailers will not be appended to the response, however any trailers parsed out of the chunked stream will be attached here instead.
