 The _referer_ should be my own server, since it is from where the POST
 originate, but in this particular case, from this IP-adress, the referer
 disapears sometimes...

Bug (or feature) of the Brwoser?

Anyway, you can't rely on Referer: header for validation of the
data, as you can spoof it easily.

Re: POST without any content - sometimes

2002-02-16 Thread Anders Knuts

I don't think it's the users browser since I got one POST with referer and one
POST without  with only three seconds between. The user runs vanilla Win XP
with MS IE5.5. I think there is a Norton Personal firewall in between, maybe
there's the problem?

Maybe the best thing to do is to make the script accept POSTs without referer
and forget tho whole thing?
On the other hand I'm a curious person :-)

I don't know about Personal Firewall, but Norton Internet Security does
indeed strip off referer tags. We discovered this at work while
debugging a similar problem. This is part of the Privacy Control
component
