[REQUEST] Keep underlying TCP stream open between multiple requests with same proxy and domain

Version of the software

0.2.4

Operating system

Windows

Browser / Native

Any

What happened?

When you use rotating proxies on one site, a new IP is taken for each request to the site.
What about a persistent connection? Keep the connection alive

PS And I didn't find it anywhere, what is the AlwaysSendContent setting for?

Relevant LoliCode if needed
