The session_dns function resolves the IP address of the client associated with a specified session into its DNS name. The function returns a newly allocated string. You can use session_dns to change the numeric IP address into something more readable.
The session_maxdns function verifies the client identification information. The session_dns function does not perform this verification.
This function works only if the DNS directive is enabled in the obj.conf file. For more information, see Sun Java System Web Proxy Server 4.0.11 Configuration File Reference.
char *session_dns(Session *sn);
A string containing the host name, or NULL if the DNS name cannot be found for the IP address.
Session *sn identifies the Session structure.
The Session is the same as the Session structure passed to your SAF.
