This is an area that we are looking to improve. In particular I am
looking into adding more options in this area, to give more control over
when timeouts are applied.
For example I am thinking something like:
NO_REQUEST_TIMEOUT - How long the server should wait between requests
PARSE_TIMEOUT - the maximum amount of time that should be spent parsing
a HTTP request
READ_TIMEOUT - When reading a request entity the maximum idle timeout
I'm not sure if this covers all the use cases though.
