Production Mode with SCGI


#1

Hi,
I have an application running on Apache SCGI (Win XP). Once I run it in
production mode (scgi_ctrl config -S -e production ) I’m getting
stack trace instead of HTTP status 500 (Application Error) and the
error is logged production.log. The application works fine without
SCGI. Your help is highly appreciated…
Thanx

/* production.log */
