Hey all,

Could anyone tell me the reason for the following..

when i use proxy switcher and switch proxies, and i check my ip on www.your-ip-address.com i get to see the changed IP. But when i check it on www.whatismyip.com i see the non-proxied ip. Could anyone tell me the reason for this.

Also when I send mail using proxy from hotmail and yahoo. Does hotmail and yahoo store the original IP as well. i.e does it detect that you are using proxy servers.

Regards
