Hi I want to do bulk queries on whois engines. Everthing works fine for a single request. whois("suneido.com") for instance. The problem is that the whois servers  are disconnecting after 1 request. I know about a few desktop whois apps which are able to do bulk queries..
Questions is what is the big trick ? This seems to be a good kept secret. Any ideas ?

The whois servers rate limit to stop spammers from farming them..

sleep() is probably your best answer....
