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..

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