Sun Java System Web Proxy Server 4.0.11 NSAPI Developer's Guide


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.

Note –

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.
