Flash cookies are traces that are (not so) hard to remove (if you know how)

The programmers of this web2.0 flashy world have a big problem. THe problem is that their interfaces are so coderich and interactive that if the server has to do everything their web2.0 multimillion riskinvested projects will so slow down that nobody will use them anymore. So they have - without telling - transferred most of the work of the server to the client and programs on the computer. For this to work they also have to transfer a lot of the information about your identity and activities to the computer. To be sure that this ain't deleted each time you delete all your cookies when you log off, some - like Flash - have made their own cookies.

A blogger (viva les bloggers :) ) has found out about it and so this has made now a headline.

"The Adobe Flash Player maintains proprietary cookies called Local Shared Objects or LSO’s. LSO’s are capable of storing 100 kb’s of information for an indefinite amount of time by default.

There’s no easy way to tell what sites are using flash cookies to track your movements. There’s no list, and there doesn’t have to be a flash GUI or visible application for flash cookies to be present

Lame as it might be, the Flash Player has no ability to delete cookies. And as I’ve already said, your browser can’t help you out. It doesn’t even know these cookies exist!"

and you will find all the necessary technical information - that is being updated and added by readers and commentators here

 

Comment shouldn't website give the possibility of choice between the flash web2.0 site and a normal text/graphic/cookie website ?
