title: close connection in LoadRunner
body: <p>Practical Challenge:
  I have a LR script that runs against an app being mocked and do not have a logout button (yet).
  The test runs fine With stable response time for about 10 minutes, but after that the response time peaks and the server goes into 99% memory usage and transactions start to fail.
  I suspect this is due to the script does not terminate the vusers after each run anf it builds up a lot of running sessions against the server wich is not terminated. But I might be wrong.
  Anyays I want to programatically close each run after it has competed the business process.
  I have red somewhere that web_set_sockets_option ("SHUTDOWN_MODE", "ABRUPT") could be used for this, but I want to be sure that this function actually does what I want and what does 'ABRUPT' means?
  Are there better ways of closing sessions? Clicking the  close browser during recording does not result in anything being captured in the script.</p>
