<Location> and <LocationMatch>
<Location URL>
...
</Location>
The <Location>
directive limits the application of the
directives within the block to those URLs specified, which can
include wildcards and regular expressions preceded by
~. In line with regular-expression processing in
Apache v1.3, * and ? no longer
match to /.
<LocationMatch> is followed by a regular
expression without the ~.
Most things that are allowed in a
<Directory> block are allowed in
<Location>, but although
AllowOverride will not cause an error in a
<Location> block, it makes no sense there.
