### プロキシ転送ヘッダーの仕組み { #how-proxy-forwarded-headers-work }

クライアントと **アプリケーションサーバー** の間で、**プロキシ** がどのように転送ヘッダーを追加するかを図示します:

predefined new function) and the term C pointer means a pointer to
memory allocated by C (such as by a call to C.malloc). Whether a
pointer is a Go pointer or a C pointer is a dynamic property
determined by how the memory was allocated; it has nothing to do with
the type of the pointer.

Note that values of some Go types, other than the type's zero value,
always include Go pointers. This is true of interface, channel, map,
