i have to query a lot of web sites (like 200-500) and it takes forever to boot all of them up and some don't exist so I have to wait for the time out sometimes. it takes 200 to 500 minutes to boot them all up. My boss only wants to know which web sites exist and the ping command is not an option. is there any way to thread all of them and boot them all up in the time it would take to query ONE?
