Proxy question

[goldenking0412]

options = { http_proxyaddr: @proxy_addr, http_proxyport: @proxy_port, http_proxyuser: @proxy_user, http_proxypass: @proxy_pass }
get_response = HTTParty.get(url, options)

The proxy returns random ip whenever call.
But if I use this proxy in browser, it keeps same ip for 15 mins.
So I want to simulate that.
How can I keep connection open and send 2nd request with 1st request ip?
this gem will work for this?
Thanks

If so, then how to use proxy in persistent httparty?
