Recent proxy change caused proxy behavior to break #578
Description
This recent proxy change released in version 0.9.3 does not appear to be working as intended. When we deployed this change, all of our requests were not going through our defined proxy. Since this appears like a regression and does not allow proxies to be used with the NetSuite gem, can we revert that change (will put up a new PR shortly) and cut a new gem version? This will fix the broken behavior for users who make NetSuite calls via proxies.
