# OVER-RIDE BLOCKER / SUPER WHITELIST
# -----------------------------------
# In this block you can allow any IP address specified here to over-ride any bad bot or IP blocking of the blocker.
# This is useful for testing or allowing only specific IP's (ie. Internal ranges) to never be blocked.
# More IP's can be added example > "(127.0.0.1)|(192.168.0.1)|(192.168.1.1)"
# If you even blacklisted 127.0.0.1 or your own IP by giving it a value of 1 in any of the includes, this will over-ride that block.

# UNCOMMENT THE NEXT 4 LINES TO ACTIVATE THE SUPER WHITELIST
#if ($remote_addr ~ "(127.0.0.1)|(192.168.0.1)" ) {
