is there a way to do this?

[madafaka]

i need to have a page that is only available if you come from certain location.
for example i want paypal to direct people that payed software on my site to the location where they can download software... is this possible?

with pure html code you can not do it. but asp or java or php or other server programming language you can it and is very simple. for example with asp with use of serverVariable can do that.
i am in doubt about paypal do that. but javascript or vbscript may be can also do the job.
