问题
I currently have deployed the following .htaccess in the directory of my CodeIgniter app:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
and the following .htaccess in my htdocs root:
RewriteEngine On
# Map / to /foo.
RewriteRule ^$ /foo/ [L]
# Map /x to /foo/x unless there is a x in the web root.
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !^/foo/
RewriteRule ^(.*)$ /foo/$1
Where foo is the directory were my CodeIgniter app lives. This redirects example.com/foo/whatever to example.com/whatever, except if it matches other directories where other apps live (fox example example.com/admin/whatever, which should be kept that way). That part of the behaviour is desired. But now I have two urls for every page on foo, I have example.com/foo/whatever and example.com/whatever. I want to make a 301 redirect for all requests from /foo/x to /x, but if I add
# Redirect /foo/x to /x
RewriteRule ^foo/(.*)$ /$1 [R=301,L]
to the .htaccess I obviously get a redirection infinite loop. The solution described here for a related question doesn't work, because it doesn't redirect to the index.php when needed. How can I achieve what I want? Thanks in advance for any help you may provide.
回答1:
Have this new rule in /foo/.htaccess to redirect /foo/abc to /abc:
RewriteEngine On
RewriteCond %{THE_REQUEST} /foo/(\S*)\s [NC]
RewriteRule ^ /%1 [L,R=301,NE]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
