mod_rewrite的力量WWW preFIX选择工作力量、工作、mod_rewrite、preFIX
我利用其他mod_rewrite的情况在我的.htaccess文件，并希望确保我的域名总是$ pfixed与WWW（会话存储和搜索引擎优化）p $。但是我目前的.htaccess如果我去到example.com，它的伟大工程，但如果我去example.com/folder~~V它会重定向到www.example.com（离开了/文件夹中）有什么我做错了在这里？
我的.htaccess文件
选项+了FollowSymLinks
RewriteEngine叙述上
的RewriteCond％{HTTP_HOST} ^例如 .COM $
重写规则^（。*）$ http://www.example.com/$1 [R = 301，L]
＃规则：动作
重写规则^（[-_！〜*'（）$ A-ZA-Z0-9] +）/ $ ./date/index.php?action=$1 [L，QSA]
解决方案
重写引擎是多通。它循环采摘最低的.htaccess 的路径与 RewriteEngine叙述在上的文件，直至不再重写发生变化。因此，对于这个 example.com/folder/xxx 请求 - 如果的.htaccess 文件存在于 DOCROOT /文件夹那么它将使用和 DOCROOT /的.htaccess 将 忽略
您可以在DOCROOT或层次使用单个的.htaccess 。单DOCROOT 的.htaccess 文件中有一个小的性能优势，因为发动机只需要打开和读取单个的.htaccess 文件。我描述得更详细些这篇文章，中更多使用.htaccess文件重写规则
您没有指定一个的RewriteBase 键，以便引擎可以常常失去目录，在这里你的情况。所以，我会用在以下 DOCROOT /的.htaccess ：
选项+了FollowSymLinks
RewriteEngine叙述上
的RewriteBase /
的RewriteCond％{HTTP_HOST} = example.com
重写规则^ * http://www.example.com/$0 [R = 301，L]
在这里DOCROOT是Apache的文档根目录。
我也很好奇你的包容性格的日期格式设置。似乎很奇怪，我，但离开这个放在一边，最好写成
重写规则^（[-_！〜*'（）$ W] +）/ $日期/的index.php？行动= $ 1 [L，QSA]
假设，当然，要激活DOCROOT /日期/ index.php文件
I am utilizing other mod_rewrite conditions in my .htaccess file and also want to ensure that my domain is always prefixed with www (for session storing and seo). However with my current .htaccess if I go to example.com it works great, but if I go to example.com/folder it will redirect to www.example.com (leaving out /folder) Is there something I'm doing wrong here?
my .htaccess file
Options +FollowSymLinks
RewriteEngine on
RewriteCond %{HTTP_HOST} ^example.com$
RewriteRule ^(.*)$ http://www.example.com/$1 [R=301,L]
# Rules for: actions
RewriteRule ^([-_!~*'()$a-zA-Z0-9]+)/?$ ./date/index.php?action=$1 [L,QSA]
解决方案
The rewrite engine is multi-pass. It loops picking the lowest .htaccess file on the path with RewriteEngine On until no further rewrite changes occur. So for this example.com/folder/xxx request -- if an .htaccess file exists in DOCROOT/folder then it will be used and the rewrite rules in DOCROOT/.htaccess will be ignored.
You can use a single .htaccess in DOCROOT or a hierarchy. The single DOCROOT .htaccess file has a small performance advantage as the engine only needs to open and to read in a single .htaccess file. I describe this in more detail in this article, More on using Rewrite rules in .htaccess files
You are not specifying a RewriteBase and so the engine can often lose directories as here in your case. So I would use the following in DOCROOT/.htaccess:
Options +FollowSymLinks
RewriteEngine on
RewriteBase /
RewriteCond %{HTTP_HOST} =example.com
RewriteRule ^.* http://www.example.com/$0 [R=301,L]
where DOCROOT is your Apache document root directory.
I am also curious about your inclusion character set for the date pattern. Seems odd to me, but leaving this aside, it's better written as
RewriteRule ^([-_!~*'()$w]+)/?$ date/index.php?action=$1 [L,QSA]
assuming, of course, that you want to activate DOCROOT/date/index.php
