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 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"';
