FreeLists / dokuwiki / [dokuwiki] Re: dokuwiki htaccess rules in conflict with other domain rewrites?

[Markus Frosch <markus@xxxxxxxxxxxxx>]

Hi Ryan
hm I missed this "merging" part of documentation...

All my experience with mod_rewrite shows me that local rules overwrites
the rules from parent directories.

Maybe this feature will be implemented in the future.

But you should not rely on this at the moment ;-)
