Just use 2 connection string inside <connectionstrings></connectionstrings> block.

Use the one you need to connect the db when you call stored procedure.

In web.config, you can have two distinct (by name) connectionstring as:

HTML

<configuration>
  <connectionstrings>
    <add name="MyConnection1" connectionstring="Data Source=server1;Initial Catalog=db1;User ID=id1;Password=pass1;" providername="System.Data.EntityClient" />
    <add name="MyConnection2" connectionstring="Data Source=server2;Initial Catalog=db2;User ID=id2;Password=pass2;" providername="System.Data.EntityClient" />
  </connectionstrings>
  <system.web></system.web></configuration>

In the code behind, you can fetch these two connection in two different holder as:

C#

private static string connectionString1 = ConfigurationManager.ConnectionStrings["MyConnection1"].ToString();
private static string connectionString2 = ConfigurationManager.ConnectionStrings["MyConnection2"].ToString();

Hope, it clarify your question.
