Beginning of Win32-CGI support (tested with php-cgi.exe) - works, but doesn't
set-up environment variables yet. Moved 301 and 302 error strings to shared string constants. http_logoff() now logs the correct socket descriptor (instead of -1) when called from http_session_thread(). is_dynamic_req() now correctly checks both the directory *and* drive of the configured cgi_dir against the requested physical path (required for Win32). Sets sane startup->max_cgi_inactivity value (2 minutes) if uninitialized.
