[MacPerl-WebCGI] HTTP_REFERER and executable questions

[Bert Altenburg <bsfa@knoware.nl>]

Hi there,

I've written a cgi script that returns the web URL last visited. However, 
it only works when the last page visited is my own web page, not when 
I've visited Apple's page last (and call the cgi directly). Could it be a 
limitation that providers impose?

I've a bit difficulty understanding the usefulness of HTTP_REFERER when I 
can see it contents only if someone lands at my site via a cgi script. 
So, I would see no posibility to see how people ended up at my website. 

When I've made a file executable, I can drag a replacement (with the same 
name) in the cgi-bin folder and I don't have to make it executable again. 
Is that the general behaviour, i.e. does the server keep a list of names 
of executable files?

Thanks for your help.

Bye for now,

Bert
