serve mode

[valdo404]

using asynchronous operators plus js operators, really implement the proxy of proxy logic.

it is divided in several parts:

• downloading already existing proxy.pac (and serving it locally)
• determining the proxy decision (control plane)

it means we are gonna ask the logic what are gonna be the proxy decision for a specific host / ip.

it can involve asynchronous logic

• executing the proxy decision with proxy failover (data plane)

basically it is gonna take a proxy decision and gonna execute it, request by request, in an optimized fashion

• inspecting the incoming requests (host, ip, ssl, etc). Should use a cache. required by execution logic

[valdo404]

implementation needs:

executing js and optimized ast code in boa
proxy subexecution
using ssl sni

when operators output can be cached, use the cache directly
