I am currently using this code to create a session based on the url the person came from. The only problem with this is that it does not work for https:// sites. Can anyone help me with the code that would work for both ssl and non ssl sites?

HTTP_REFERRER does not work if the page came from javascript rather than a normal link. And as far as I know, the same absence of HTTP_REFERRER info also happens with SECURE html pages. The reason is, they are secure, and do not transfer requests to non-secure pages. There may be a way around it in ASP but I don't know of any in PHP.
here is some reading material

B Dorsey, thank you for the comments once again but I have already read that and many other posts in experts-exchange already trying to find a solution. What I am looking for here is the actual code that I would need to get this to work.
I am not a devloper and do not know how to write code, hence my post in experts-exchange for help.
"There is at least one special issue with HTTP_REFERER for SSL requests, which is that a link for an https link on an http page (note that there's no s -- it's a non-secure page with links to a secure page), then the HTTPS RFC states that the Referer header value should not be sent."
So it short terms it will NOT work for a link to your site that was a HTTPS (its an RFC standard)
But if you want to continue ... Somehting like
<%
Dim refURL,refDomain
refDomain = ""
refURL = lcase(request.servervariab
if refURL <> "" then
Dim sptDomain
if Instr(refURL,"/") > 0 then
sptDomain = split(refURL,"/")
if UBound(sptDomain) >= 2 then
if Instr(sptDomain(2),".") > 0 then
Dim curDomain
curDomain = split(sptDomain(2),".")
refDomain = curDomain(UBound(curDomain
end if
end if
end if
end if
Session("allowaccess") = "0"
if refDomain <> "" then
if refDomain = "somedomain.com" then
Session("allowaccess") = "1"
end if
end if
if Session("allowaccess") = "1" Then
'allow
else
response.redirect ("error.htm")
end if
%>
