I am testing a .htaccess with just
ErrorDocument 403 "Forbidden"
ErrorDocument 404 "missing"
inside it. If I go to example.com/blahblah
the server stalls for a few seconds and then returns a blank page (this is in Firefox/Opera as IE can't deal with short error pages)
I assume you mean a forthcoming 3.1.1 release as the one you gave me the other day is what I am using and it does not obey ~username .htaccess
