推荐答案

您是在谈论服务器端重写(如 Apache mod-rewrite)吗?对于那些，地址栏通常不会改变(除非执行重定向).或者你在谈论重定向?这些是通过让服务器使用 HTTP 代码(301、302 或 307)和 HTTP 标头中的位置进行响应来完成的.

Are you talking about server-side rewrites (like Apache mod-rewrite)? For those, the address bar does not generally change (unless a redirection is performed). Or are you talking about redirections? These are done by having the server respond with an HTTP code (301, 302 or 307) and the location in the HTTP header.
