The examples show the HSL::open command being run in the CLIENT_ACCEPTED event. So, will every new connection grab a new handle for HSL logging? Could the HSL::open command go inside RULE_INIT, and if so, is it likely to improve performance?

 

 

I'm just trying to figure out if the LTM could "run out" of available handles for HSL under load.

 

 

thanks for any reply

 

I was informed that there isn't actually any gain in trying to use a shared handle for HSL as HSL internally caches and garbage-collects message queues and connections.
