有关正常的客户，谁不清空缓存了？有多长302重定向保存在浏览器

For the "normal" client who does not empty his cache: How long is the 302 redirect kept in the browser?

推荐答案

它不应该在所有缓存，除非还有一个的Cache-Control 或到期由Web服务器返回头。据 RFC 2616，第10.3.3节302找到

It shouldn't be cached at all unless there's also a Cache-Control or Expires header returned by the web server. According to RFC 2616, section 10.3.3 302 Found

请求的资源在不同的URI暂住。由于重定向可能会偶尔被改变，客户端应该继续使用Request-URI为将来的请求。如果一个缓存控制指示，或者Expires头域这种反应只缓存。

The requested resource resides temporarily under a different URI. Since the redirection might be altered on occasion, the client SHOULD continue to use the Request-URI for future requests. This response is only cacheable if indicated by a Cache-Control or Expires header field.
