Well basically I have a scraping application. It scrapes around n items per minute. currently i have only one IP.

The site i'm scraping allows me 3 connections per IP.

I'm thinking about getting another IP.

so i'll be able to get 6 connections.

in theory i should be able to get n items in 40 seconds, more or less.

currently i'm using java (commons-httpcore) to get the job done.

I'm not sure if this is java question or an OS question.

my machine has IP 1 and IP 2 how do i connect to, say, www.microsoft.com, using IP 1 and using IP2? how can i specify, which ip i want to use to do a connection?
