I had to append the path because I was getting the error that import
DBconnectpropman could not be found. Somehow the path gets lost. I
also try adding the following to the httpd.conf:
PythonPath "sys.path+['/home/brianheadrentals/www/brianheadrentals.com>'
]"
But it didn't make a difference. They are about 10 python scripts for
the whole site and for each one if I don't do the sys.path.append it
fails to find it. Is there another way to fix it?
In regards to flushing out the headers. You mean that before doing:
R.write("<head><meta http-equiv='refresh'
content='0;url=BB.html'></head>")
I should do:
R.send_http_header()
right?
