HTTP/1.1 302 到底是什么意思? [英] What does HTTP/1.1 302 mean exactly?

问题描述

我曾经读过的一些文章说这意味着跳转(从一个 URI 到另一个 URI)，但即使实际上根本没有跳转，我还是检测到了这个302"！

Some article I read once said that it means jumping (from one URI to another), but I detected this "302" even when there was actually no jumping at all!

推荐答案

302 重定向意味着页面被临时移动，而 301 意味着它被永久移动.

A 302 redirect means that the page was temporarily moved, while a 301 means that it was permanently moved.

301s 有利于 SEO 价值，而 302s 不是因为 301s 指示客户忘记原始 URL 的值，而 302 保留原始 URL 的值，因此可以通过创建两个逻辑来潜在地降低价值 -每个产生相同内容的不同 URL(搜索引擎将它们视为不同的重复项，而不是具有两个名称的单个资源).

301s are good for SEO value, while 302s aren't because 301s instruct clients to forget the value of the original URL, while the 302 keeps the value of the original and can thus potentially reduce the value by creating two, logically-distinct URLs that each produce the same content (search engines view them as distinct duplicates rather than a single resource with two names).
