* * Added support for environment variables to 'templates' module.
* Fixed flaw in test caused by environment variable ordering during testing on CI.
* Updated some local variables to camel-case.
* Reverted changes to replacer as environment variables are processed elsewhere.
* Removed PrintEnv functionality in favour of documenting using template range.
* Fix for stripping of 'Content-Disposition' and other headers from 'X-Accel-Redirect' redirect scripts.
* Added test case for header manipulation of redirect response.
First, great job on the 0.9 release! It seems caddy's path lead into a bright future. Thanks also for including the locale plugin.
Trying it, I've figured out, that there might be a problem with the order of the directives. In the typical use case, the result of the locale detection might be used in the `rewrite` and `log` plugin. If I'm not mistaken, it makes sense to put the `locale` directive before those.
* Allow for UDP servers
Extend the Server interface with ServePacket and ListenPacket - this is
in the same vein as the net package.
Plumb the packetconn through the start and restart phases.
Rename RestartPair to RestartTriple as it now also contains a Packet.
Not that these can now be nil, so we need to check for that when
restarting.
* Update the documentation
If we listen on 127.0.0.1:80 for `localhost` but :80 for everything else,
then a hostname in the hosts file that resolves to 127.0.0.1 will be
served on :80 (unless the bind directive is used) but the OS will use
the socket listening at 127.0.0.1:80, thus giving a "No such site" error
even though the site is there, but it's on the other listener at :80.
Two ways to fix this: 1) Leave as-is and require the user to set "bind
127.0.0.1" in their Caddyfile for all sites that are resolved in the
hosts file, or 2) Take out this special case and let localhost sites
listen on :80 (unless the user changes that with the bind directive, of
course). Having localhost bind to any interface is a little annoying
(unsettling?) but probably best in the long run.

OnStartup and OnShutdown callbacks now run as part of restarts, too.
The startup and shutdown directives only run their commands NOT as part
of restarts, as before. Some middleware that use OnStartup may need to
switch to OnFirstStartup and implement OnFinalShutdown to do any cleanup
as needed.
* checkpoint
* Added RequestMatcher interface. Extract 'if' condition into a RequestMatcher.
* Added tests for IfMatcher
* Minor refactors
* Refactors
* Use if_op
* conform with new 0.9 beta function changes.
- 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.
* Add timeout to http get on health_check
* Add new test and up the timeout
* Tests for change to default timeout
* Only call http client once and make options more inline with current caddy directives
This commit shouldn't change any behavior. It is simply a cleanup of
the different proxy policies. It also adds some comments explaining the
sampling method used, since on first inspection it might not appear to
be a uniformly random selection.
* Balance round robin evenly when some hosts are down
Before, when load balancing across multiple hosts, if a host went down
then the next host in line would be sent a double share of requests.
This is because the round robin counter was only incremented once per
request, regardless of the health of the selection. If current
selection was unhealthy then the policy would advance to the next host,
but this would not be reflected in the policy counter. To fix this, the
counter is now incremented for every attempted host.
This commit adds a test case that identifies the issue, and a fix.
* Make robin counter private
* Use a mutex to sync round robin selection
Also we change the scheme of the site's address if TLS is enabled and
no other scheme is explicitly set; this makes it appear as "https" when
we print it; otherwise it would show "http" when TLS is turned on
implicitly, and that is confusing/incorrect.
