Removing www from URL and using directory-like URL's - apache

Question

I have an issue removing the www from an URL. Also I want to use directory-like URL's (e.g. When I type www.foo.com/bar/baz into URL bar, it is converted into foo.com/index?page=bar&action=baz in the background and only in the background). But what I'm getting is that when I type in the URL with www and hit an Enter, I get back a foo.com/index?page=bar&action=baz in the URL bar. I only want foo.com/bar/baz to appear. (If I already wrote the URL without www, it's working fine.)
This is my code (only changed the original URL's):
RewriteCond %{HTTP_HOST} ^www\.foo\.com$ [NC]
RewriteRule (.*) http://foo.com$1 [L,R=301]
RewriteCond %{REQUEST_URI} !/index\.php
RewriteCond %{REQUEST_URI} !/Views/.*\.js
RewriteCond %{REQUEST_URI} !/Views/.*\.css
RewriteRule ^([^/]+)/([^/]+)(/[^/]+)* /index.php?page=$1&action=$2 [L,QSA]
RewriteCond %{REQUEST_URI} !/index\.php
RewriteCond %{REQUEST_URI} !/Views/.*\.js
RewriteCond %{REQUEST_URI} !/Views/.*\.css
RewriteRule ^([^/]+) /index.php?page=$1 [L,QSA]
So my question is obviously: What am I doing wrong and how can I make it work?

Answer 1

There may be some other Apache rules in play but from the look of it there may be an issue with slashes. It would be better if your first rule was this --
RewriteRule (.*) http://foo$1 [L,R=301]
Without the trailing slash. The reason for this is you will create a double // when redirecting www.foo.com/foo/bar. It will redirect to foo.com//foo/bar.
Your other rules should start with /, e.g. --
RewriteRule ^/([^/]+)/([^/]+)(/[^/]+)* /index.php?page=$1&action=$2 [L,QSA]
And --
RewriteRule ^/([^/]+) /index.php?page=$1 [L,QSA]
