No "Log In" required to db after first "Log In"

[David Scott]

I have several working dB's for clients, using FM 5. They're published on the web using HTML and CDML. They all have the same problem, but I'll use one for example. I have set the Web Security up to have username "All Users" (with no password or permissions) and the other username and password with browse, edit and create privileges. When the client first accessed the dB it requested his username and password. Now he can access it without going through "Log In" by either using the "Back" button or by a link from his favorites. I don't want the dB accessible without Logging In. I can replicate the same situation on my computer. How do I require a "Log In" every time, unless they click "save password"?
