What is the difference between these headers? Did you check the $proxy_add_x_forwarded_for variable documentation? the X-Forwarded-For client request header field with the $remote_addr variable appended to it, separated by a comma. If the X-Forwarded-For field is not present in the client request header, the $proxy_add_x_forwarded_for variable is equal to the $remote_addr variable. If the incoming … Read more
No: “Messages MUST NOT include both a Content-Length header field and a non-identity transfer-coding. If the message does include a non-identity transfer-coding, the Content-Length MUST be ignored.” (RFC 2616, Section 4.4) And no, you can use Content-Length and stream; the protocol doesn’t constrain how your implementation works.

It’s easiest just to copy the Origin header of the request to this field. It’s entirely unclear why the standard would disallow a wildcard. Firefox … Read more
In which layer is HTTP in the OSI model? It’s in the application layer. See the following quotes from the RFC 7230, one of the documents that currently defines the HTTP/1.1 protocol: The Hypertext Transfer Protocol (HTTP) is a stateless application-level request/response protocol that uses extensible semantics and self-descriptive message payloads for flexible interaction with … Read more
Actually, this will send a POST request request to the server, so technically you aren’t mixing the two together : you are using POST with url parameters. There is nothing fundamentally wrong with this, as long as you don’t use your URL for parameters that should be in the form as hidden field. There are … Read more
From Wikipedia : According to RFC 6838 (published in January 2013 : https://www.rfc-editor.org/rfc/rfc6838), any use of types in the “x.” tree is strongly discouraged. Media types with names beginning with “x-” are no longer considered to be members of this tree since January 2013. Then use directly application/msgpack

RFC 2616 has this to say (amongst other things) about Content-Length: Applications SHOULD use this field to indicate the transfer-length of the message-body, unless this is prohibited by the rules in section 4.4.
