Data Structures
struct	ap_fcgi_header
	A structure that represents the fixed header fields at the beginning of a "FastCGI record" (i.e., the data prior to content data and padding). More...

struct	ap_fcgi_begin_request_body
	This represents the content data of the FastCGI record when the type is AP_FCGI_BEGIN_REQUEST. More...
