Checking for phone type is an excellent idea. We add a timestamp in the
encrypted UID but doesn't network resolution dramatically increase
transaction time?

Greetings Kyle
We use a totally random and unidentifiable 64bit ID and on subsequent
sessions also check the ID against the session parameters (ie its the
same phone type on the same network). Its about as far as you can go
whilst being compatible across the the differing standards. We are
implimenting logging and monitoring on page requests that will pick up
any attempt at scanning.

Agreed that a UID is the best (only) way to maintain session
state.
X-UP-SUBNO and DoCoMo's unique subscriber ID (for those lucky
enough to
have access to it), are useful for maintaining content
personalization
beyond the session.
We normally use a simple counter from our DB table to generate
the UID
although you may want to throw some encryption at this before
attaching
it to a URL.

Jimmy,
Supporting the 3 different phone systems from a single
application is
problematic for this and other reasons. If you also try to
support
Palm, PocketPC h", DotI as well it gets even worse as there are
almost
no consistancies.
The only sure way to maintain a session is produce a unique ID
yourself
and append it to the URL.
We have this code as part of a product we base all our projects
upon,
it's called mIntadev. We currently have built it on JSP/Java,
ASP
(sortof) and are working on a PHP version.
At some time in the future we will release it as Open Source,
but at the
moment its still a bit 'industrial'.
However, I'm happy to give you (or selected others that would
like it)
the code parts you require, or the whole application on a trail
licence
basis.
E-mail me directly or call the office during the week 03 5549
2830
Regards,
David Davies
