Access webpage from subdirectory as root page

Question

I have two websites:

http://example.com http://example.com/sub

I have a page, let's say:

http://example.com/sub/page1

Is there any way (using .htacces) to make it possible to access page1 via this url:

http://example.com/page1?

Redirect 301 won't do the work, because I don't need redirects. Is there any way to omit '/sub/' for certain urls, like http://example.com/sub/page1 ?

Answer 1

Yep, there is. Do the following within your .htaccess:

<IfModule mod_rewrite.c>
RewriteEngine On

# This would rewrite any URL that starts with /sub to /
RewriteCond %{REQUEST_URI} /sub
RewriteRule ^sub/(.*)$ /$1 [L]
<IfModule>
