mod_rewrite writing local routes - apache

Question

You see, I want to redirect [R] from http://www.domain.com/dir1/ to http://www.domain.com/.
I also want to accept http://www.domain.com/dir1/([0-9]+) and [L] those requests to dir1.php?query=$1. And to [L] all http://www.domain.com/dir1/(.+) to the root.
So these are my rules:
RewriteRule dir1/([0-9]+) dir1.php?query=$1 [L]
RewriteRule dir1/(.+) $1 [L]
RewriteRule dir1/ . [R,L]
The problem with the last one (and I tried many variations of it) is that redirects to http://www.domain.com/home/domain/www/. I mean, that inserts the local directory. I just want it to redirect to http://www.domain.com/
Thanks,

Use a path with a slash to redirect the client to some absolute path.
RewriteRule dir1/ / [R,L]
The mistake is using . instead of /.
This comes straight from the RewriteRule examples:
Inside per-directory configuration for /somepath
(/physical/path/to/somepath/.htacccess, with RewriteBase /somepath)
for request ``GET /somepath/localpath/pathinfo'':
Given Rule Resulting Substitution
---------------------------------------------- ----------------------------------
[... snip ...]
^localpath(.*) /otherpath$1 /otherpath/pathinfo
In our case /otherpath is just / and we don't use $1 since we don't want the local part.
You can also redirect using absolute URLs. That is useful for redirecting http requests to https or going to other websites. You can redirect to the same server like this:
RewriteRule dir1/ http://%{HTTP_HOST}/ [R,L]
But this is needlessly complicated.
