Adding new domain extensions

We have tried to support most of the TLDs that have whois servers available and also some that only have access via the registrars website, by using functions to access that site.
If there are other TLD's you would like to support let us know and we can see if they are possible.
You can also check availability for non supported TLDs by checking for the NS server. This is not as reliable but it may be sufficient for many applications where the actual who information is not needed. To add this support for specific TLD's add lines to cwhois (near the other entries) like this
$dtd[]=".ext,ns,not found";
Replace the .ext with the TLD required.
