Referrer tracking

Hi all

I've just written a VERY simple shopping cart system for my own joy and
edification as much as anything else. Mostly it was an exercise in learning
about sessions but I want to keep adding to it.

What happens at the moment is that it starts a session when the visitor
enters the site. As soon as the visitor adds something to their cart it
adds a row into a table where the session id is used as the unique
identifier in the table. The table also has columns for the product id and
price (joining tables will be my next learning curve)

One of the things I want to be able to do is affiliate tracking. The way I
have it in my head is that there will be an extra column for refid (or
something) so that:

www.whatever.com?refid=1234

will be used. 1234 will then get written to the table when the visitor
starts to add stuff to there cart.

What I need to know is

1. Is this reinventing the wheel? Is there a better way already
2. If the user hits the site and just looks around for a while, how do I
make sure that the refid variable is maintained until they add something to
their cart?

Hope this makes sense.

Andy

I normally have an enter page that creates a cookie and then redirects to
site home page. When adding items to cart I check the referrer cookie. The
cookie can expire as soon as visitor closes browser or can be kept for some
days: that depends on your referrers policy.

Referrer Logs - Strange Entries

by: Ryann | last post by:

Hello. I had a strange entry in my referrer logs. The http-referrer reported that the user came from another site. But the file it claimed to come from a pdf file. I followed the link back and as a PDF file it clearly doesn't have a link back to our side. Under what circumstances might this happen? Thanks in advance!

http_referer different than document.referrer - why?

by: Mike Dee | last post by:

Hi All - I'm having a strange problem I'm wondering if anyone can shed some light on. When I use ASP or ASP.NET code to get the referrer information from the server side, it comes back as null. However in these same cases document.referrer returns the valid referrer. What could cause this? In other words, with the following line: ref = Request.ServerVariables("HTTP_REFERER") (or its ASP.NET equivalent)

Problem With Comparison Operator <=> in G++

by: Oralloy | last post by:

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

The easy way to turn off automatic updates for Windows 10/11

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
