+ DNS resolution for origin domains
+ The DNS domain resolution happens when the socket to
+ the origin server is created for the first time.
+ When connection pooling is used, the DNS resolution is performed
+ again only when the ttl
of the connection expires
+ (please check ProxyPass
+ parameters).
+ This means that httpd does not perform any DNS resolution caching.
