ADK needed for thirdparty API conn pool management

Has anyone used the ADK for connecting to a third-party’s API through web services? I see there is a “Connection Management” service described in the ADK user’s guide that dynamically manages connections and connection pools but I’m not sure if that applies to connections made by a web service soap login.

Or is there a better way to create a “resource handler” to manage a connection pool? Connecting to the API using a SOAP login is successful but the need is to have multiple sessions alive and available when incoming documents are received. Calling the login (and logout) each time affects performance.
