To delete a DNS entry:
For example, if you would like to delete an unexpected negative dns cache entry for foo.bar.com, enter:
SGOS v5.x: https://<IP-Addr:8082>/CE/DNS/delete/foo.bar.com
SGOS v6.x: https://<IP-Addr:8082>/DNS/cache/delete/foo.bar.com
To verify the DNS cache entry information, click Show information on a DNS entry and append the hostname to the end of the URL.
For example:
SGOS v5.x: https://<IP-Addr:8082>/CE/DNS/info/foo.bar.com
SGOS v6.x: https://<IP-Addr:8082>/DNS/cache/info/foo.bar.com
