Safari缓存GET请求(即使禁用了缓存) [英] Safari Caching GET request even with disabled cache

问题描述

我已经设置了我知道的所有标头，以在服务器上禁用缓存(甚至禁用ETAG)，但是Safari仍然偶尔(约50％次)缓存我的请求.

I have set all headers that I know of to disable caching (even disabling ETAG) on my server, yet Safari still occasionally (about 50% times) caches my requests.

我正在实现oauth 1，所以:

I am implementing oauth 1, so:

1. 浏览器发出GET /api/user请求

服务器返回405

浏览器重定向到第三方网站进行身份验证

Browser redirects to 3rd party website to authenticate

浏览器重定向到api/callback，它将一些信息存储到cookie中.

Browser is redirected to api/callback which stores some info into cookie.

浏览器被重定向回原始路由.

Browser is redirected back to original route.

浏览器发出GET /api/user请求，该请求应该成功，但是它会从磁盘缓存中获取405服务.

Browser makes GET /api/user request which should be successful, however it gets 405 served from disk cache instead.

或者，您可以通过在网址中包含一些无意义的随机查询arg来强制浏览器加载新版本的请求，例如/api/user?ts=18284

Alternatively, you can really force browser to load a new version of request by including some meaningless random query arg in your url, e.g. /api/user?ts=18284
