Yes Steven googleign for 2 hours now.

You were rigth about the carret it was a synatx error above which i 
missed and i was breakign my head to the wall to understand what was wot 
with the 'host' variable. why python doestn detect the exact synxtax 
error and ispoitnign to me to another line making me think the error is 
elsewhere?

This indeed works now:

ref = os.environ.get('HTTP_REFERER', 'Άγνωστο Ref')

but iam wondering why this doesnt work also:

ref = os.environ('HTTP_REFERER')

Shouldnt both work?
