An entry in the etsysTwcbWebcacheServerHostDenyTable defining
a range of source IP addresses for this TWCB Webcache server
Host Deny Table entry. The TWCB Webcache server Host Deny
Table entry defines a range of source IP addresses for which
HTTP requests will not be allowed to be redirected by TWCB.
If no TWCB Webcache Server Host Permit entry or TWCB Webcache
Server Host Deny entry exists than all source IP addresses
will be allowed. A TWCB Webcache Server Host Deny entry takes
presidency over any created TWCB Host Permit entries. If an
address falls within a defined TWCB Webcache Server Host Deny
range of addresses than that address will be denied
regardless if it also falls within a TWCB Webcache Server
Host Permit entry.
