毫秒内要做些什么 - 竞价请求解析（JSON 或 Google Protobuf） 根据广告位属性过滤活动 根据客户端信息过滤活动（浏览器、操作系统类型等） • 根据地区过滤活动 • 查询Cookie Mapping得到访客在DSP系统的唯一ID 根据用户看过广告的频次过滤活动 根据访客的人群属性过滤活动 根据活动的出价选择胜出的活动 - 其他更细致的过滤条件 ## 为什么选择Golang ## Save和重启时Load数据的时间 - 一致性要求不是非常高的业务，可以把自动的BgSave关闭，在凌晨或者空闲时候手动调用BgSave ## CookieMapping • 广告投放时是用Cookie来定向用户的 - CM保存了DSP与ADX（如百度、淘宝）间CookieId的映射关系 - 在RTB竞价的时候，DSP可以根据ADX-CookieId从映射表中获取到DSP-CookieId 独立部署 • 方便更新与重启 ./bin --- adx_mod --- analysis --- bid --- charge --- convrate_import --- cookie_map --- dispatch --- ip_import --- kpicharge --- pdmp --- whisky ## 部署：进程管理 • Go不支持以后台进程的方式启动

What’s going on? • I’m setting a cookie, but it isn’t being returned in subsequent requests. How can I serve a downloadable file with falcon classes in the same module. A proposal has been made to add a new routing feature that will afford mapping related routes to a single resource class, if so desired. To learn more, see #584 on GitHub [https://github

重写维持会话跟踪的方法；理解 Cookie 和 Session 的协同机制，掌握使用 Cookie 和 Session 实现会话跟踪的技术。 3. 能够使用 Cookie 和 Session 编写会话跟踪代码。 ## 大纲 会话基本概念 会话跟踪技术 URL 重写 Cookie Java EE 会话对象 本节习题 ## 接下来… 会话基本概念 会话跟踪技术 URL 重写 Cookie Java 服务器保持客户状态信息。 3. Cookie 使用 Java EE API 提供的 Cookie 对象，可以将客户信息保存在 Cookie 中，完成会话跟踪功能。 4. HttpSession 对象 Java EE API 专门提供了 HttpSession 会话对象保存客户的信息来实现会话跟踪。 一般 3 和 4 组合使用。 ## 接下来… 会话基本概念 会话跟踪技术 URL 重写 Cookie Java Java EE 会话对象 本节习题 ## 接下来… 会话基本概念 会话跟踪技术 URL 重写 Cookie Java EE 会话对象 本节习题 ## URL 重写的实现 ## ① 浏览器端构造 URL 请求 在进行 HTTP 请求时，可以在 URL 地址后直接附加请求参数，把客户端的数据传输到 Web 服务器端。 Web 服务器通过 HttpServletRequest 请求对象取得这些
