Hi...

Did you ever think about identifying a user, visiting your wap-site, by his
subscriber ID?

It won't always work!

And this is the problem:
The Wap Gateway (mostly driven by your provider) has the ability to send
some additional info to your webserver. Some of those infos are slightly
valuable. UP.Link (Gateway by Phone.com) for example provides HTTP_X_UP_SUBNO
(used like REMOTE_ADDR) which contains a worldwide unique ID of the subscriber.
You could use it to identify your customer on your WAP-Site. (Really, this
is much better than using cookies!)
Well, the problem is, not all of the providers forward HTTP_X_UP_SUBNO to
the webserver.

Another problem is, some providers don't provide a Cookie-Proxy. So you can't
rely on cookies either.

Do YOU know how to identify users permanently?
