<div>Hi,<br></div><div><br></div><div>I am going to use post_action for mirroring the load for performance testing to new backend.<br></div><div><br></div><div>But according to the doc: </div><div><br></div><div>>> Note: this directive "has subtleties" according to Maxim Dounin, so use at your own risk.</div>
<div><br></div><div>Some questions:</div><div><br></div><div>1. Is the post_action blocking to the user request? Or the sub request is truly async and not affecting to the user?</div><div>2. And caveat is using high load env, e.g. stability?</div>
<div> </div><div><br></div><div>So anyone mind share your experience?</div><div><br></div><div>Thanks.</div>
