我的铁路3.2 应用程序的用途——通过stale? - Ref>Ref-modized-Since HTTP 请求中的标题,和Last-modifed 头在答复中决定它是否应动态生成某些数据。在开发过程中(无论是使用 webrick还是独角兽_rails),这作为 curl-D headers.txt 非常有效,这表明如果提供正确的 If-modifed-Since 值,则发送304份答复,而“code>Lest-modeded 头则随请求数据发送。
不幸的是,一旦在 nginx 后面布置, " code>If-modifed-Since (提供正确的页头价值)既没有传给独角兽,因此,铁路应用程序也向客户宣传了 " 铁路应用程序 " 和 " Last-modifed
结果发现 nginx 实际上没有剥去任何东西。 仪器显示控制器收到了 lif- modifed- Since 。 铁路 nil 参数, 静静地吞没它, 随后忽略了比较 fif- mided- Since 和定位 Last-modized 以 nil 。
