I found this in my apache access logs
access.log:555.555.555.555 - - [05/May/2011:12:12:21 -0400] "GET /somedir/ HTTP/1.1" 403 291 "-" "Mozilla/5.0 (X11; Linux x86_64; rv:5.0) Gecko/20100101 Firefox/5.0"
access.log:555.555.555.555 - - [05/May/2011:12:12:29 -0400] "GET /somedir/ HTTP/1.1" 200 7629 "-" "Mozilla/5.0 (X11; Linux x86_64; rv:5.0) Gecko/20100101 Firefox/5.0"
So /somedir/ has .htaccess file which looks like
Order Deny,Allow
Deny from all
Allow from 333.333.333.333
Allow from 444.444.444.444
htaccess was not modified within timeframe (8 seconds between 12:12:21 and 12:12:29
Any ideas how this is possible to hit 403 Forbidden and then 8 sec later 200 OK; I'm puzzled
