I try to do this with:
referer = os.environ.get('HTTP_REFERER', 'UnknownRef')
but that doesn't return anything either.
And of course that's bolloks:

Can you verify that its the correct way to grab the referral string?
It is.
The Referer is not an environment variable.
It is when you're writing a CGI app.
How would your shell know what URL you were just browsing?
Because the HTTP server sets those environment variables before
invoking the CGI app.
So you mean that even if i run it via shell this stement will also work
because it happens to be in the same enviroment with the HTTP server?
No need to run it via web browser and check the Apache's error log?
