How can I save user options

Question

Hello guys
Is there any way to save the users preferences in my application for later use?
for example the user clicks tools >> options. and there he/she choose one of three choices and this choice must be saved for the next use.

Answer 1

true. But that doesn't represent a user on the
serverside.
Many computers are used by more than one person under
the same login, in which case those would all share
the same options for the web application as set by
the last one changing them from that terminal.
On another terminal their settings would be
different.
By storing the information on the server they'd
always get their own settings, not just when using
their private machine but also when visiting
elsewhere.If all users work under one userid on the client computer (or the server ignores the client id), then the only way your approach works is to maintain a full user database on the server with each user's id, passwords, preferences, and validation routines, and require that every user log on for each access of the server. In most cases, a single session involves multiple server accesses during a transaction, which would be impossible to handle correctly.
This is not a good approach from both the security aspect - each user should be logging on to the client machine using their own userid - and the usability aspect.
I recommend against this approach.
