Using altered %{REQUEST_URI} in RewriteCond file exists check
提问by Alistair
I'm wanting to take a URL such as http://localhost/universe/networks/o2/o2_logo.gifand do the following:
我想要一个 URL，例如http://localhost/universe/networks/o2/o2_logo.gif并执行以下操作：
If it begins with /universe/
Strip /universe/ from it to become /networks/o2/o2_logo.gif
Check if this exists in %{DOCUMENT_ROOT}/networks/o2/o2_logo.gif
If so, silently rewrite the request to this file.
If I use a rule of:
如果我使用以下规则：
RewriteCond %{REQUEST_URI} ^/universe/
RewriteRule ^(.*)$ http://www.example.org/ [L]
http://localhost/universe/networks/o2/o2_logo.gifgets re-written to http://www.example.org/networks/o2/o2_logo.gifwhich is great, but I can't seem to use the
http://localhost/universe/networks/o2/o2_logo.gif被重新写入http://www.example.org/networks/o2/o2_logo.gif这很棒，但我似乎无法使用
How can I go about using this 'changed' %{REQUEST_URI} further down as say $1 or something?
我怎样才能继续使用这个“改变”的 %{REQUEST_URI} 进一步向下说 $1 或其他东西？

I was not able to get this right purely with .htaccess but used the following file:
我无法完全使用 .htaccess 来解决这个问题，但使用了以下文件：
RewriteEngine On
# Does the file exist in the content folder?
RewriteCond %{REQUEST_URI} !^/content.*
RewriteCond %{DOCUMENT_ROOT}/universe/%{REQUEST_URI} -f
# File Exists
RewriteRule ^ %{DOCUMENT_ROOT}/universe/%{REQUEST_URI} [L]
# If the request is not a file, link or directory then send to index.php
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L] # Item exists so don't rewrite
# Nothing exists for the request so append a trailing / if needed
RewriteCond %{REQUEST_URI} !/$
RewriteRule ^ %{REQUEST_URI}/ [R=301,L]
RewriteRule ^.*$ index.php [NC,L] # Send off as-is to index.php
Then I went into my document_root folder and did the following:
然后我进入我的 document_root 文件夹并执行以下操作：
cd /var/www/journal
ln -s journal/public universe
cd /var/www/journal/public
ln -s content/ universe
That combined with the htaccess meant everything was working.
结合 htaccess 意味着一切正常。

Try this rule:
试试这个规则：
RewriteCond %{DOCUMENT_ROOT} -f
RewriteRule ^universe/(.*) [L]
