### HttpUserId The module ngx_http_userid_module gives out cookies for identification of clients. For logging it is possible to use variables `$uid_got` and `$uid_set`. Remark: keep in mind variables $uid_got and $uid_set are not accessible in SSI, because SSI filter module working before userid filter. This module is compatible with [mod_uid](http://www.lexa.ru/programs/mod-uid-eng.html "http://www.lexa.ru/programs/mod-uid-eng.html") for Apache. Example ~~~ userid on; userid_name uid; userid_domain example.com; userid_path /; userid_expires 365d; userid_p3p 'policyref="/w3c/p3p.xml", CP="CUR ADM OUR NOR STA NID"'; ~~~ ### 鎸囦護 ### userid **syntax:***userid [on|v1|log||off]* **default:***userid off* **context:***http, server, location* Enables or disables issuing cookies and logging requested cookies: - on - enables version 2 cookies and logs them; - v1 - enables version 1 cookies and logs them; - log - do not send cookies, but write down incoming cookies to log; - off - do not send cookies, and don't write them to logs; ### userid_domain **syntax:***userid_domain [ name | none ]* **default:***userid_domain none* **context:***http, server, location* Assigns the domain for cookie.
