499s % in production traffic

Hello NGINX Community,

  • It is my understanding 499 is a client side response code indicating
    the
    remote user prematurely closed the connection without finishing the
    transaction.

  • I have a production environment which is reporting 0.3%-0.5% of total
    traffic accounting to this 499 response code with pages already
    optimized
    to deliver as fast as we can.

Id like to ask if somebody can contribute what the experience with this
response code has been in terms of percentage, and if this range is
considered a safe minimal low to be expected in a production site.

Thanks
JG
