Difference	Maxwell	Tesla
Adapter	support send_file send_stream send_multipart	httpc ibrowse adapter don't support send file stream multipart
Method	build get/* and get!/*	only build get/*
Middleware	be able to check argument and set default options in compile time	don't support check argument in compile time
Connection	store req_headers, req_body, resp_body, resp_headers	replaces env’s headers and body by response, lead to lose req_headers and req_body context

PS: About Dynamic API clients.

Maxwell: only manipulating connection details by the Maxwell.Conn help functions.
