Hi Paul, thanks for bringing it back. Got some questions:
1. In your RFC $_ENV is bound to $request. Looking at HttpFoundation can see it's build from $_GET, $_POST, $_FILES, $_COOKIE, $_SESSION and then looking at PSR ServerSideRequest it's build from $_COOKIE, $_GET, $_POST, $_FILES, $_SERVER but none of them bounds $_ENV. Server environment variables basically don't change over time when server process runs. What is the specific use case that requires them to be coupled with $request instance? 2. In your RFC all headers are mapped to $request properties This behaviour is unclear and unusual to me, for eg. in summary can see that if server request has "Header-Name" it is found in $_SERVER["HTTP_HEADER_NAME"] and that one is bound to $request->headers["header-name"], ok but the next line with example for "Content-Type" shows that it's bound to $request->contentType - which means probably that it can be accessed in $request->headers["content-type"] as well, right? seems logic. Going further, for eg. $_SERVER["PHP_AUTH_PW"] is bound to $request->authPw and then what will happen if the request will receive "Auth-Pw" header? a) It'll be bound to $request->headers["auth-pw"] ? b) It'll be bound to $request->authPw ? c) None of above. With those above I would see a set of getters like getContentType() or getAuthPassword() etc. instead of ServerRequest instance properties and a single point to retrieve header values just like well known ParameterBag's from HttpFoundation to operate on get, post, headers etc. BR, -- Michał Brzuchalski
