Original feature request in forum:
https://forum.caddyserver.com/t/caddy-with-specific-hosts-but-on-demand-tls/1704?u=matt
Before, Caddy obtained certificates for every name it could at startup.
And it would only obtain certificates during the handshake for sites
defined with a hostname that didn't qualify at startup (like
"*.example.com" or ":443"). This made sense for most situations, and
helped ensure that certificates were obtained as early and reliably as
possible.
With this change, Caddy will NOT obtain certificates for hostnames it
knows at startup (even if they qualify) if OnDemand is enabled.
But I think this change generalizes well, because a user who specifies
max_certs is deliberately turning on On-Demand TLS, fully aware of
the consequences. It seems dubious to ignore that config when the user
deliberately put it there. We'll see how this goes.
* Create list of index files based on extensions and check on a per config
basis
* remove log lines
* fixed tests
* made gofmt suggested change
* Changes made to simplify
* Respect the 'insecure_skip_verify' for the health check.
* WIP: Trying to add a test. Non functional.
* Fixing tests.
* Creating better error messages.
* Optimize two more error messages.
* Move the tests into an extra function.
* Add a shutdown function and context to staticUpstream so that running goroutines can be cancelled. Add a GetShutdownFunc to Upstream interface to expose the shutdown function to the caddy Controller for performing it on restarts.
* Make fakeUpstream implement new Upstream methods.
Implement new Upstream method for fakeWSUpstream as well.
* Rename GetShutdownFunc to Stop(). Add a waitgroup to the staticUpstream for controlling individual object's goroutines. Add the Stop function to OnRestart and OnShutdown. Add tests for checking to see if healthchecks continue hitting a backend server after stop has been called.
* Go back to using a stop channel since the context adds no additional benefit.
Only register stop function for onShutdown since it's called as part of restart.
* Remove assignment to atomic value
* Incrementing WaitGroup outside of goroutine to avoid race condition. Loading atomic values in test.
* Linting: change counter to just use the default zero value instead of setting it
* Clarify Stop method comments, add comments to stop channel and waitgroup and remove out of date comment about handling stopping the proxy. Stop the ticker when the stop signal is sent
Previously directories have been merely pulled to the front, and then
sorted arbitrarily. That is, their order among themselves depended on
the filesystem implementations. Something opaque to the visitor.
This fixes said inconsistency, and implements the by-size-then-by-name
order I initially intended for this.
* Use helper functions in staticfiles to redirect.
Previously the browse package invoked staticfiles.Redirect when
redirecting clients who requested a directory but with a Request-URI
that did not contain a trailing '/'. staticfiles.Redirect only used a
relative URI. This change defers the decision of how to format the
Location header value to the helper methods in the staticfiles package.
* Update const URLPathCtxKey in browse package.
* Add the first policy which sends the request to the first available host
* Make the error message clear. As we expect the second not first upstream
host.
* Fixed issue with {path} actually {uri}
* Test added for path rewrite
* add in uri_escaped
* added rewrite_uri and test
* fix broken test. Just checks for existance of rewrite header
* gitignore
* Use context to store uri value
* ignore .vscode
* tidy up, removal of comments and invalidated tests
* Remove commented out code.
* added comment as requested by lint
* fixed spelling mistake
* clarified code with variable name
* added context for uri and test
* added TODO comment to move consts
* Fixed#1484
Fixed a nil pointer runtime error in newConnHijackerTransport,
where the access to the TLSClientConfig did not check for nil values.
* Minor improvement to UseInsecureTransport
This prevents overwriting a possibly preexisting TLSClientConfig,
even though only a single field should be changed.
* add support for listener middleware
* add proxyprotocol directive
* make caddy.Listener interface required
* Remove tcpKeepAliveListener wrapper from Serve()
This is now done in the Listen() function, along with other potential middleware.
* Fix for missing content-length header when using QUIC
If request.ContentLength is set then it will be used instead of getting
it from request.Header map since quic-go(lucas-clemente/quic-go@bb24be8)
will not store (and pass) the Content-Length header using its header
map.
This fixes a potential issue where FastCGI POST requests body empty when
QUIC is enabled. (#1370)
* Change the data type for fastcgi contentLength to int64
quic-go uses int64 for contentLength
* Fix an error for undeclared variable
* Fix test for fcgiclient
the data type for contentLength
* Support realms with basic authentication
* Add test for default basicauth directive in which realm is not specified
* Correct typo: missing space
* Remove 'path' subdirective
If use gzip and templates at the same time, the response body will
be gzipped data. And in this case, the Content-Type header won't be
set by Caddy code. Then Go http package will set "Content-Type" to
wrong value "application/x-gzip" which is determined by response body.
So the header Contenty-Type should be set in templates middleware.
This commit removes _almost_ all instances of hard-coded ports 80 and
443 strings, and now allows the user to define what the HTTP and HTTPS
ports are by the -http-port and -https-ports flags.
(One instance of "80" is still hard-coded in tls.go because it cannot
import httpserver to get access to the HTTP port variable. I don't
suspect this will be a problem in practice, but one workaround would be
to define an exported variable in the caddytls package and let the
httpserver package set it as well as its own HTTPPort variable.)
The port numbers required by the ACME challenges HTTP-01 and TLS-SNI-01
are hard-coded into the spec as ports 80 and 443 for good reasons,
but the big question is whether they necessarily need to be the HTTP
and HTTPS ports. Although the answer is probably no, they chose those
ports for convenience and widest compatibility/deployability. So this
commit also assumes that the "HTTP port" is necessarily the same port
on which to serve the HTTP-01 challenge, and the "HTTPS port" is
necessarily the same one on which to serve the TLS-SNI-01 challenge. In
other words, changing the HTTP and HTTPS ports also changes the ports
the challenges will be served on.
If you change the HTTP and HTTPS ports, you are responsible for
configuring your system to forward ports 80 and 443 properly.
Closes#918 and closes#1293. Also related: #468.
* Use RequestURI when redirecting to canonical path.
Caddy may trim a request's URL path when it starts with the path that's
associated with the virtual host. This change uses the path from the request's
RequestURI when performing a redirect.
Fix issue #1327.
* Rename redirurl to redirURL.
* Redirect to the full URL.
The scheme and host from the virtual host's site configuration is used
in order to redirect to the full URL.
* Add comment and remove redundant check.
* Store the original URL path in request context.
By storing the original URL path as a value in the request context,
middlewares can access both it and the sanitized path. The default
default FileServer handler will use the original URL on redirects.
* Replace contextKey type with CtxKey.
In addition to moving the CtxKey definition to the caddy package, this
change updates the CtxKey references in the httpserver, fastcgi, and
basicauth packages.
* httpserver: Fix reference to CtxKey
Timeouts are important for mitigating slowloris, yes. But after a number
of complaints and seeing that default timeouts are a sore point of
confusion, we're disabling them now. However, the code that sets
default timeouts remains intact; the defaults are just the zero value.
While Caddy aims to be secure by default, Caddy also aims to serve a
worldwide audience. Even my own internet here in Utah is poor at times,
with bad WiFi signal, causing some connections to take over 10s to
be established. Many use the Internet while commuting on slower
connection speeds. Latency across country borders is another concern.
As such, disabling default timeouts will serve a greater population of
users than enabling them, as slowloris is easy to mitigate and does
not seem to be reported often (I've only seen it once). It's also very
difficult sometimes to distinguish slowloris from genuine slow networks.
That decision is best left to the site owner for now.
* tls: Refactor TLS config innards with a few minor syntax changes
muststaple -> must_staple
"http2 off" -> "alpn" with list of ALPN values
* Fix typo
* Fix QUIC handler
* Inline struct field assignments
* Store name of authenticated user in basicauth for use by upstream middleware such as fastcgi and cgi.
* Use request context to transfer name of authorized user from basicauth to upstream middleware. Test retrieval of name from context.
* Remove development code that was inadvertently left in place
* Use keys of type httpserver.CtxKey to access Context values
