有条件地使用mod_rewrite重定向流量取决于协议

标签： apache .htaccess mod-rewrite apache2

我一直在编写重写规则，尝试将所有流量从mysite.com.au重定向到www.mysite.com.au。我还需要有条件地重定向，具体取决于是否启用SSL。

我已经从askapache.com攻击了一下，创建了一个依赖于 http 或 https 的变量。以下是我正在使用的代码：

    RewriteCond %{HTTPS} =on
    RewriteRule ^(.+)$ - [env=ps:https]
    RewriteCond %{HTTPS} !=on
    RewriteRule ^(.+)$ - [env=ps:http]
    RewriteCond %{HTTP_HOST} ^mysite\.com\.au(.*)$ [NC]
    RewriteCond %{HTTP_HOST} !^$
    RewriteRule ^(.*)$ %{ENV:ps}://www.mysite.com.au/$1 [L,R=301]

这适用于带路径的网址（例如mysite.com.au/foo重定向到www.mysite.com.au/foo）并执行 http 和 https 转好。

然而，当只是访问域名（只是mysite.com.au）时，它会重定向到http://www.mysite.com.au/home/website/public_html/:/www.mysite.com.au/

我确信这是一个非常小而基本的东西，我很想念 - 如果有人能够指出它，那就不胜感激了。

谢谢！

我找到了答案 - 这与乍看之下的情况完全不同。

我打开 RewriteLog ，我发现了问题。在日志中，如果我使用我的原始条件/规则并使用mysite.com.au/test，我会看到以下内容：

    10.1.1.1 - - [11/Feb/2013:11:37:50 +1100] [mysite.com.au/sid#b81d24f8][rid#b847d100/initial] (3) [perdir /home/website/public_html/] strip per-dir prefix: /home/website/public_html/test -> test

    10.1.1.1 - - [11/Feb/2013:11:37:50 +1100] [mysite.com.au/sid#b81d24f8][rid#b847d100/initial] (2) [perdir /home/website/public_html/] rewrite 'test' -> 'http://www.mysite.com.au/test'

但是当我在mysite.com.au上运行时，我看到了：

    10.1.1.1 - - [11/Feb/2013:11:38:16 +1100] [mysite.com.au/sid#b81d24f8][rid#b845bc18/initial] (3) [perdir /home/website/public_html/] strip per-dir prefix: /home/website/public_html/ ->

    10.1.1.1 - - [11/Feb/2013:11:38:16 +1100] [mysite.com.au/sid#b81d24f8][rid#b845bc18/initial] (2) [perdir /home/website/public_html/] rewrite '' -> '://www.mysite.com.au/'
    10.1.1.1 - - [11/Feb/2013:11:38:16 +1100] [mysite.com.au/sid#b81d24f8][rid#b845bc18/initial] (3) [perdir /home/website/public_html/] add per-dir prefix: ://www.mysite.com.au/ -> /home/website/public_html/://www.mysite.com.au/
    10.1.1.1 - - [11/Feb/2013:11:38:16 +1100] [mysite.com.au/sid#b81d24f8][rid#b845bc18/initial] (2) [perdir /home/website/public_html/] explicitly forcing redirect with http:/.makeitmine.com.au/home/website/public_html/://www.mysite.com.au/

请注意，我正在尝试设置的环境变量（SSL开/关）未设置。因此，它没有看到http / https前缀，并假设它是一个相对的内部路径！

当我尝试设置环境变量时，我使用以下代码：

    RewriteCond %{HTTPS} =on
    RewriteRule ^(.+)$ - [env=ps:https]
    RewriteCond %{HTTPS} !=on
    RewriteRule ^(.+)$ - [env=ps:http]

^（。+）$的RegEx预计至少有1个字符，这是不匹配的！我修改如下：

    RewriteCond %{HTTPS} =on
    RewriteRule ^(.*)$ - [env=ps:https]
    RewriteCond %{HTTPS} !=on
    RewriteRule ^(.*)$ - [env=ps:http]

现在它匹配，即使是0个字符！

再次感谢您的帮助，问题解决了：）
