Switch Sites Overview
If the data must be accessed from separate site databases, then the user must select a configuration from the list and tap the Switch link to "switch sites." Behind the scenes, a URL is built that includes the name of the Web server, the new configuration, the current form, and the user's name. A login screen to the other site is displayed. If you want the switch to be seamless, without requiring the user to enter a password, then set up the user with a Workstation login in that site.
The use of the Switch Sites feature assumes that all of your sites use the same Web client on the same Web server. It also assumes that users set their browsers to allow pop-ups. When you select Switch, you are logged out of the current session and a pop-up window opens with the new login information.
