CGI Variable HTTP_REFERER

[OceanBear]

I am trying to determine where a visitor comes from when arriving at my website - wanting to give credit where it is due and for curiosity as well.

I had understood hat this is a simple matter of looking at the HTTP_REFERER CGI variable.

My first attempt failed because there was no indication of an arrival at index.html (duh).

So I tried to be clever and made a tiny webpage which did nothing other than to send a request directly to the server to produce my home page - and - still empty.

So how can we get this information?

You will have to use the ENV (environment) collection. Here is a resource which may be helpful.
