+## keepsession功能
+* 需要在config.php开启
+* 如果请求的get或post或cookie中带有keepsession=1，则这条记录会被keepsession
+* 请设置脚本或者网站监控定期访问keepsession.php
+* 请将cookie存在cookie参数，url存在location参数（传递方法可get可post可cookie），如`index.php?keepsession=1&cookie=aaa&location=bbb`,keepsession.php将会定期使用cookie aaa去访问bbb
+* cookie和location参数支持base64编码，keepsession.php会自动判断，自动解码
+* 如果不设置location，将会使用HTTP Referer作为url
+* keepsession.php使用`flock($pid, LOCK_EX|LOCK_NB)`实现单例运行（由于windows下不支持无阻塞锁定，所以最好删除keepsession.php里的`set_time_limit(0)`），可自行加上sleep防止keepsession.php被恶意频繁访问
