OneConnect Profile Max-Reuse of Zero

The answer is that in the case of zero, it means that there will be no reuse at all. The backend connection will be used only once and then destroyed.

In the case of one, the connection is used twice: once for the initial request and then once for reuse.

This is similar to a case where the 'Connection: close' response header is returned. The difference being that the frontend connection is not actually closed but the LTM treats it as if it had by resetting to the default pool of the virtual server as well as resetting any iRule variables.

F5 agrees that the documentation could be more clear on this matter and have taken an action item to do so.
