Keep Alive

Hi - testing our SOAP API. We need to send a logon method which returns a session ID which we copy and paste, crudely speaking, into other methods before they can be tested.

Unfortunately, the login method drops the connection after 15 secs and so the session ID becomes invalid. 

Wed Jul 18 13:14:08 BST 2018:DEBUG:Connection can be kept alive for 15000 MILLISECONDS

How can I alter that timeout please?

Thanks

David
