Using reselect method to keep http session persistence

Better read the article for this feature https://support.f5.com/csp/article/K15095 as it has good description for this feature:

==========

This option is only appropriate for:

• Virtual servers with address and port translation disabled

  Note: This is the default for network virtual servers, such as wildcard IP Forwarding virtual servers.

• Transparent pool members, such as firewalls, routers, proxy servers, and cache servers

  Note: Transparent devices can forward packets to destinations without regard for the state of the connection.

• UDP virtual servers
  
  Important: Because this setting does not re-establish TLS or any other stateful protocol, you should not use it in a reverse-proxy deployment where pool members are stateful endpoints.
