That will work.

It also matches a filename like 'blah,1,foo'

If you want to make sure the '1' is the first letter of
the filename, write it like this:

        acl MYRULE url_regex /1,

The ^ and $ characters "match" the beginning and end of a
string only. See http://jmason.org/software/sitescooper/tao_regexps.html
