Is This Normal Php Behaviour?

[Hifk]

Hi

I tried to use getenv('HTTP_REFERER') to get the referring url ie find out where my user came from... but on localhost i keep getting a blank...

I checked phpinfo() and the referrer was in fact blank...

Is this normal behaviour?

PS it is spelt HTTP_REFERER and not HTTP_REFERRER because some programmer at the time didnt spell it correctly
