What I do is to have something like this in a configuration file:

[System]
ConnectionString=1

[ConnectionString]
ConnectionString1=Provider=VFPOLEDB.1;Data Source="d:\iis\MyWebSite\App_Data";Password='';Collating Sequence=MACHINE
ConnectionString2=Data Source=MyPC;Initial Catalog=My Catalog;Integrated Security=True
ConnectionString3=Provider=VFPOLEDB.1;Data Source="d:\iis\MyWebSite2\App_Data";Password='';Collating Sequence=MACHINE

So, at run time, you can read the configuration file and know which connection string to use.
