Sorry for so many messages but I'm trying to share as much info as possible
to get over this hurdle.
I have been able to resolve the "Unable to change working directory to
'/home/bhaarat'." error in error_log by specifying a home directory in
WSGIDaemonProcess like this:
WSGIDaemonProcess /processimages user=bhaarat group=bhaarat processes=2
threads=3 home=/var/www/webpy-app/ display-name=%{GROUP}
However, when I access the url: curl --insecure
"https://localhost/processimages?color=red&shade=dark"; I still get internal
server error and the error I posted earlier in ssl_error_log:
