# INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS
#

# Example rule allowing access from your local networks.

	Allowing or Denying access based on defined access lists

	To allow or deny a message received on an HTTP, HTTPS, or FTP port:
	http_access allow|deny [!]aclname ...

	NOTE on default values:

	If there are no "access" lines present, the default is to deny
	the request.

	If none of the "access" lines cause a match, the default is the
	opposite of the last line in the list.  If the last line was
	deny, the default is allow.  Conversely, if the last line
	is allow, the default will be deny.  For these reasons, it is a
	good idea to have an "deny all" entry at the end of your access
	lists to avoid potential confusion.

	This clause supports both fast and slow acl types.
