(keitai-l) Cookies or not Cookies.. That's the question

Hi Folks,

We are using Coldfusion to make an application for keitai and PC browsers.
The same pages are being viewed by J-Phone/DoComo and MS-IE.
We decided to not make separated pages for each technology prefering to 
lead with the exceptions inside each page for those three browser types.
The problem is that I need to pass info between the pages and cookies
are not supported by keitais. 
Is there any tip to turn around this problem?

Thanks in advance,

Isamar
