+ 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. +
