mod_rewrite Configuration for All Subdirectories

Question

In Apache HTTPD 2.2, I want to make it so requests for /index.foo or /foo, if they aren't files or directories, become /index.php?transform=foo, regardless of how many levels the URL has.

Criteria for success would be:

• http://www.site.example/index.foo -> http://www.site.example/index.php?transform=foo
• http://www.site.example/foo -> http://www.site.example/index.php?transform=foo
• http://www.site.example/bar/baz/foo -> http://www.site.example/bar/baz/index.php?transform=foo

I.e., I don't want rewrites to be relative to the .htaccess directory; I want them to be relative to the topmost directory in the request.

Answer 1

# Check if file exists
RewriteCond %{REQUEST_FILENAME} ! -f

# Rewrite the URI if file doesn't exist and contains "index."
RewriteRule ^(.*)(index\.[^/]+)$ $1/index.php?transform=$2 [L]

# The same thing for any other URI
RewriteCond %{REQUEST_FILENAME} ! -f
RewriteRule ^(.*)([^/]+)$ $1/index.php?transform=$2 [L]

Answer 2

Solved it using two modified versions of the regex from this page:

# $1 = directory, $2 = extension
# Matches:
# - /html
# - /web/portfolio/html

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*/)?(html|rss|txt)$ $1index.php?transform=$2 [L]

# $1 = directory, $2 = "index.", $3 = extension
# Matches:
# - /index.html
# - /web/portfolio/index.html

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*/)?(?:$|(index\.)(?:([^.]*$)|$))$ $1$2php?transform=$3 [L]
