If a FastCGI enabled application wants to know what the limits of the FastCGI server are before beginning to make requests, then this behavior requires two separate FastCGI connections - one to obtain the information and another to make the actual request. In addition, the conditions of a general-purpose FastCGI server can change between connections. FCGI_GET_VALUES is not considered to be an actual request as it is a management record type AND the FastCGI specification mandates that the client drives server connection/disconnection (not the other way around). As a result, PHP's behavior is not compliant with the FastCGI spec. Test script: --------------- Analysis: The fcgi_read_request() function returns 0 back to the caller (fcgi_accept_request()) when handling FCGI_GET_VALUES. That, in turn, results in calling fcgi_close(), which terminates the connection. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=76922&edit=1
