* Convert rwc field on FCGIClient from type io.ReadWriteCloser to net.Conn.
* Return HTTP 504 to the client when a timeout occurs.
* In Handler.ServeHTTP(), close the connection before returning an HTTP
502/504.
* Refactor tests and add coverage.
By setting the read deadline in streamReader.Read(), the deadline was
extended by the read timeout on each subsequent call. To avoid this, the
deadline is set in FCGIClient.Request(), before the first read occurs.
See #1094.
* Make fastcgi load balanceable too
* Address one more corner case - invalid configuration fastcgi /
* After review fixes
* Simplify conditions
* Error message
* New fastcgi syntax
* golint will be happy
* Change syntax
- Server types no longer need to store their own contexts; they are
stored on the caddy.Instance, which means each context will be
properly GC'ed when the instance is stopped. Server types should use
type assertions to convert from caddy.Context to their concrete
context type when they need to use it.
- Pass the entire context into httpserver.GetConfig instead of only the
Key field.
- caddy.NewTestController now requires a server type string so it can
create a controller with the proper concrete context associated with
that server type.
Tests still need more attention so that we can test the proper creation
of startup functions, etc.
