* Add upstream header replacements (TODO: tests, docs)
* Add tests, fix a few bugs
* Add more tests and comments
* Refactor header_upstream to use a fallthrough; return regex errors
By using option ca_certificates in proxy block it is possible now to select
CA against which backend certificates shall be checked.
Resolves#1550

* Adding {when_unix_ms} requests placeholder (unix timestamp with a milliseconds precision)
* Add an 499 HTTP status code on user's cancel request as NGINX doing (instead of 502 Bad Gateway status with 'Context canceled' message)
* 499 HTTP status code was added as constant CustomStatusContextCancelled = 499
* Updates the existing proxy and reverse proxy tests to include a new fallback delay value
* Adds a new fallback_delay sub-directive to the proxy directive and uses it in the creation of single host reverse proxies
* Fix 502 errors for requests without headers
* Add unexported roundRobinPolicier
We have to preserve state for fallback mode of Header policy, so
it's required to save state in some variable
* Enabled configurable Timeout for the proxy directive
* Added Test for reverse for proxy timeout
* Removed Duplication in proxy constructors
* Remove indirection from multiple constructors and refactor into one
* Fix inconsistent error message and refactor dialer initialization
* Proxy can now use QUIC for upstream connections
Add HandshakeTimeout, change h2quic syntax
* Add setup and upstream test
Test QUIC proxy with actual h2quic instance
Use different port fo QUIC test server
Add quic host to CI config
Added testdata to vendor
Revert "Added testdata to vendor"
This reverts commit 959512282deed8623168d090e5ca5e5a7933019c.
* Use local testdata
go vet caused a build fail in https://travis-ci.org/mholt/caddy/jobs/248392875:
upstream_test.go:480::error: possible formatting directive in Error call (vet)
This patch changes the Error call added in commit 078c991574 to
an Errorf call to support the use of the %d token.
See discussion on commit c9b022b5e0
If we overwrite the Server header, it becomes difficult/impossible to
know from the client whether the request was proxied through Caddy.
* Add uri policy test cases
* Add function definition
* Add uri hashing policy
* Refactor and extract hostByHashing and use in IP and URI policy
* Rename to URIHash

* proxy: added 'health_check_port' to upstream
* proxy: `net.JoinHostPort` instead of `fmt.Printf` for upstream checks
* proxy: changing health_check_port type (int->string)
adding tests for invalid port config
* httpserver/all: Clean up and standardize request URL handling
The HTTP server now always creates a context value on the request which
is a copy of the request's URL struct. It should not be modified by
middlewares, but it is safe to get the value out of the request and make
changes to it locally-scoped. Thus, the value in the context always
stores the original request URL information as it was received. Any
rewrites that happen will be to the request's URL field directly.
The HTTP server no longer cleans /sanitizes the request URL. It made too
many strong assumptions and ended up making a lot of middleware more
complicated, including upstream proxying (and fastcgi). To alleviate
this complexity, we no longer change the request URL. Middlewares are
responsible to access the disk safely by using http.Dir or, if not
actually opening files, they can use httpserver.SafePath().
I'm hoping this will address issues with #1624, #1584, #1582, and others.
* staticfiles: Fix test on Windows
@abiosoft: I still can't figure out exactly what this is for. 😅
* Use (potentially) changed URL for browse redirects, as before
* Use filepath.ToSlash, clean up a couple proxy test cases
* Oops, fix variable name
* 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
* 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.
