Consider (e.g.) Yahoo Groups. Each message is represented by an html link, so when you read them the links change colour courtesy of the browser. Could you build on that?
Of course if you go to another machine they will all be blue again (and that is exactly what happens on Yahoo Groups).

Store only what they have read and display it accordingly. Ade -----Original Message----- From: Justin [mailto:[EMAIL PROTECTED] Sent: 26 January 2004 17:43 To: Cfuk Subject: [ cf-dev ] Efficient implementation of Read/Unread messages/articles etc. Hi, I'm looking to do an efficient method of adding a read/unread icon to messages/articles etc. There are potentially 10000s of users and 10000s of messages, so the data can get pretty big fast. I'll probably end up with cheating e.g. only hold the data for messages in the last 2 weeks or something along those lines, but thought I'd ask in case someone has come up with a great solution I hadn't thought of. Cheers, Justin. -- ** Archive: http://www.mail-archive.com/dev%40lists.cfdeveloper.co.uk/ To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] For human help, e-mail: [EMAIL PROTECTED] -- ** Archive: http://www.mail-archive.com/dev%40lists.cfdeveloper.co.uk/ To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] For human help, e-mail: [EMAIL PROTECTED] -- ** Archive: http://www.mail-archive.com/dev%40lists.cfdeveloper.co.uk/ To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] For human help, e-mail: [EMAIL PROTECTED]
