Query Parent Cache for Domains

This property enables you to specify parents the Netra j Proxy Cache Server will contact only for URLs with matching domain names or, alternatively, with non-matching domain names.

Entries have the form hostname domain_name or hostname !domain_name. For example, if you have a parent wbyeats, in the same domain as the Netra j proxy cache server, to which you want directed all traffic related to URLs that contain the domain names sales.acme.com and eng.acme.com, you make an entry:

wbyeats sales.acme.com eng.acme.com

If you have multiple entries for one host--for example, in addition to the above, if you had: wbyeats fin.com--the domains in those entries are combined to form a single list.

You can also have a reverse match on domain names, so that requests related to URLs that contain domain names that do not match the specified domains are directed to the specified host. So, for example, if you want wbyeats to field all requests related to domains other than the domain names sales.acme.com, you make an entry:

wbyeats !sales.acme.com

Note that with the reverse-match feature, you can specify only one domain name, either as the only domain name in an entry or as the last domain name in an entry. If you want to prevent use of a given parent for multiple domains, specify additional entries. For example:

wbyeats !sales.acme.com
wbyeats !eng.acme.com
