.htaccess - mod-rewrite not changing the input url

Question

mod-rewrite question.

Why the following code

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^search/(.*)$ http://www.example.com/forms/index.php?i=$1 [QSA,L]

results in the url changing from

http://www.example.com/search/foo/bar

to

http://www.example.com/forms/index.php?i=foo/bar

while the following code:

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^search/(.*)$ /forms/index.php [L]

does not change the input url?

Any insight?

Thanks.

Answer 1

因为当你有http://www.example.com, mod_rewrite隐式重定向时，它与放入R规则的标志相同。

在mod_rewrite 文档中，在“替换字符串”下它说：

绝对网址

如果指定了绝对 URL，mod_rewrite 会检查主机名是否与当前主机匹配。如果是这样，则方案和主机名将被删除，并且生成的路径将被视为 URL 路径。否则，将对给定 URL 执行外部重定向。要强制将外部重定向回当前主机，请参见下面的 [R] 标志。
