class=""><span class="">because i set $uid_reset not empty, $uid_set
would get a new uuid every time nginx process a request.</span></p><p

of $uid_set, that means $uid_set did not get a value. even though over
92% request have correct value of $uid_set, but the 2% do not. And i did
not found abnormal of those request.</span></p><p class="">Do you have
any idea about this?</p><p class="">looking forward your reply!</p><p
