apache2 redirectmatch

Hi, i have a problem with apache2
Server version: Apache/2.0.55
Server built: Jul 26 2006 17:59:52

I tired to use redirectmatch option on virtualserver to redirect all
sub-URL's to main site. My idea was:
RedirectMatch ^/(.*)$ /
or
RedirectMatch ^/.+$ /
I think that's the same. But this does not work, I get info i my web
browser about ciclic redirect.
I found out that when exclude a '.' or 'x' char from regexp it works.
For example
RedirectMatch ^/[^.]+$ /
or
RedirectMatch ^/[^x]+$ /

Any sugestions?
Anyone knows why '.' and 'x' cannot be used together?
