I am building an webapp for data entry. This will be on the companies intranet all over the world, which is divided in to four regions. A user will beable to pick one regions(database) complete their tasks and switch to a different region (database) and work in that environment. I am not sure how to do this. I am thinking I need 4 different .ini files for the different connection strings. Ihave the user interface as four bottons, the user clicks their region and goes on from there. Any iedas?
