Hi I want the users in a Struts application to be only logged in once at any one time. What is the best way to go about this. I was thinking that I can have have some sort of record in (an application wide bean)/(a database record)/(the logon action) that keeps track of who is logged on and when the log on process happens this record is checked, if the user is already logged on then don't let them log on again. The problem I can see with this is that this works fine if the user logs out of the application through a logout action - the logout action can simply clear the record of the user being logged in. But if the users browser crashes, they reboot the machine, they simply restart the browser then this record will not be cleared and thus they will not be able to log in. I cannot think of how I can implement a mechanism to ensure only one log in at a time. The thought of adding some sort of timeout value seems a little nasty, since I hate it when I go to a site and I am told I am alread logged in, please try back in 10 minutes.
Any ideas folks on how to handle this? -- Cheers Tony --------------------------------------------------------------------- _________________________________________________________ Do You Yahoo!?
