What
The sandbox's HTTPS proxy now logs each denied request with its method, URL and the reason it was denied, so a blocked network call is traceable rather than silently failing.
Details
- The proxy takes a denial callback; the log message is assembled at the time of the denial.
- When an incoming request has a body but the outgoing headers ended up with neither
content-lengthnortransfer-encoding, the proxy setstransfer-encoding: chunkedso the body is still framed correctly. - If either side of the connection died while the request filter was running, the proxy now tears the connection down cleanly.
