X-Git-Tag: SQUID_3_1_0_1~49^2~286

Add support for the resolv.conf domain directive, and also automatically derived default domain

this patch adds the domain resolv.conf directive, similar to search but
only accepting a single domain.

In addition it adds support for automatically deriving the domain from
the fully qualified hostname.
