Rewrite ignoring files in a directory when it exists - mod-rewrite

Question

I have been using successfully the following rewrite that takes www.site.com/123/abc to points it to www.site.com/index.php?id=123&page=abc
RewriteEngine On
RewriteRule ^([0-9]+)$ http://%{HTTP_HOST}/$1/ [R,L]
RewriteRule ^([0-9]+)/(.*)$ /index.php?id=$1&page=$2 [L]
Until now. When a directory that exists and matches the $1 www.site.com/123/ the files in the /123/ directory I no have access to. If I try changing the rewrite to the following everything stills works except the files.
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([0-9]+)$ http://%{HTTP_HOST}/$1/ [R,L]
RewriteRule ^([0-9]+)/(.*)$ /index.php?id=$1&page=$2 [L]
What would one use to keep using mod rewrite and not ignore files in a directory when it exists.

Answer 1

RewriteConds only apply to the very next RewriteRule. Since you have two rules you need to repeat your conditions.
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([0-9]+)$ http://%{HTTP_HOST}/$1/ [R,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([0-9]+)/(.*)$ /index.php?id=$1&page=$2 [L]
Or you could filter out files and directories at the top before continuing with your rewrite rules:
# Do nothing if URL points to existing file or directory.
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule (.*) $1 [L]
RewriteRule ^([0-9]+)$ http://%{HTTP_HOST}/$1/ [R,L]
RewriteRule ^([0-9]+)/(.*)$ /index.php?id=$1&page=$2 [L]
