<div dir="ltr">Hello, master of nginx, I have a question when using ngx_http_userid_module. here is the detail description:<div><br></div><div>nginx version:1.7</div><div>conf:</div><div>
<p class=""><span class="">log_format main </span>'$remote_addr - $remote_user [$time_local] "$request" $uid_set'</p>
</div><div>...</div><div>
<p class=""><span class="">server {</span></p>
<p class=""><span class=""> userid on;</span></p>
<p class=""><span class=""> userid_name user_id;</span></p>
<p class=""><span class=""> set $uid_reset myuid;</span></p><p class=""><span class=""> ...</span></p><p class=""><span class="">}</span></p><p class=""><span class=""><br></span></p><p 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 class=""><span class="">but i found some strange things, I got value "-" 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 class="">have a nice day!</p><p class=""><span class=""><br></span></p><p class=""><span class=""><br></span></p></div></div>
