apache mod_rewrite 还是 mod_alias？

mod_rewrite or mod_alias?

提问by jeph perro

I have a server, its httpd.conf already has some "RedirectMatch permanent" directives in it.

我有一个服务器，它的 httpd.conf 中已经有一些“ RedirectMatch Permanent”指令。

I'm not that familiar with mod_alias, I've only ever used mod_rewrite.

我对 mod_alias 不太熟悉，我只使用过 mod_rewrite。

What's the basic difference? I don't see a "L" flag in mod_alias to stop processing rules.

基本的区别是什么？我在 mod_alias 中没有看到“L”标志来停止处理规则。

Which one should I use for best practices of redirecting from one sub-domain to another?

对于从一个子域重定向到另一个子域的最佳实践，我应该使用哪一个？

Can I use both at the same time and will it be obvious which takes precedence?

我可以同时使用两者吗，哪个优先？

mod_alias is basically a simpler version of mod_rewrite. It can't do some things that mod_rewrite can, such as manipulate the query string. If you're able to choose either of them, I don't see any reason that you'd want to use mod_alias.

mod_alias 基本上是一个更简单的 mod_rewrite 版本。它不能做一些 mod_rewrite 可以做的事情，比如操作查询字符串。如果您能够选择其中任何一个，我看不出您有任何理由想要使用 mod_alias。

Is there a specific reason you need to try to use both together?

是否有特定的原因需要尝试同时使用两者？

Apache mod_rewrite & mod_alias tricks you should knowseems to be a good article about the two. It notes at one point that mod_rewrite rules get executed before mod_alias ones.

你应该知道的 Apache mod_rewrite & mod_alias 技巧似乎是一篇关于这两者的好文章。它在某一时刻注意到 mod_rewrite 规则在 mod_alias 规则之前执行。

As the accepted answer says: mod_rewritecan do things which mod_aliascan't. However the main benefit of mod_aliasis that it is easier to use.

正如公认的答案所说：mod_rewrite可以做不能做的事情mod_alias。然而，主要的好处mod_alias是它更容易使用。

The apache docs say that we should use mod_aliasfor simple things like redirects and mod_rewriteonly for things we cannot do with simpler modules like mod_alias. View the docs: When not to use mod_rewrite.

apache 文档说我们应该mod_alias用于简单的事情，比如重定向，并且mod_rewrite只用于我们不能用更简单的模块做的事情，比如mod_alias. 查看文档：何时不使用 mod_rewrite。
