ProcessEnv returns FastCGI environment variables associated with the request r for which no effort was made to be included in the request itself - the data is hidden in the request's context.

Serve accepts incoming FastCGI connections on the listener l, creating a new goroutine for each.

ErrConnClosed is returned by Read when a handler attempts to read the body of a request after the connection to the web server has been closed.

ErrRequestAborted is returned by Read when a handler attempts to read the body of a request that has been aborted by the web server.
