2021-03-29reverseproxy: Implement health_uri, deprecate health_path, supports query ↵Francis Lavoie
(#4050) * reverseproxy: Implement health_uri, replaces health_path, supports query Also fixes a bug with `health_status` Caddyfile parsing , it would always only take the first character of the status code even if it didn't end with "xx". * reverseproxy: Rename to URI, named logger, warn in Provision (for JSON)

2021-02-22reverseproxy: Add duration/latency placeholders (close #4012) (#4013)Matt Holt
* reverseproxy: Add duration/latency placeholders (close #4012) (and #2268) Adds 4 placeholders, one is actually outside reverse proxy though: {http.request.duration} is how long since the server decoded the HTTP request (headers). {http.reverse_proxy.upstream.latency} is how long it took a proxy upstream to write the response header. {http.reverse_proxy.upstream.duration} is total time proxying to the upstream, including writing response body to client. {http.reverse_proxy.duration} is total time spent proxying, including selecting an upstream and retries. Obviously, most of these are only useful at the end of a request, like when writing response headers or logs. See also: https://caddy.community/t/any-equivalent-of-request-time-and-upstream-header-time-from-nginx/11418 * Add new placeholders to documentation
2021-02-09reverseproxy: Response buffering & configurable buffer sizeMatthew Holt
Proxy response bodies can now be buffered, and the size of the request body and response body buffer can be limited. Any remaining content that doesn't fit in the buffer will remain on the wire until it can be read; i.e. bodies are not truncated, even if the buffer is not big enough. This fulfills a customer requirement. This was made possible by their sponsorship!

2021-01-04reverseproxy: Caddyfile health check headers, host header support (#3948)yaxin
* reverse_proxy: 1.health check headers can be set through Caddyfile using health_headers directive; 2.health check header host can be set properly * reverse_proxy: replace example with syntax definition inline health_headers directive parse function * bugfix: change caddyfile_adapt testcase file from space to tab * reverseproxy: modify health_header value document as optional and add more test cases
2021-01-04caddyfile: Introduce basic linting and fmt check (#3923)Matt Holt
* caddyfile: Introduce basic linting and fmt check This will help encourage people to keep their Caddyfiles tidy. * Remove unrelated tests I am not sure that testing the output of warnings here is quite the right idea; these tests are just for syntax and parsing success.

2020-11-20headers: Support default header values in Caddyfile with '?' (#3807)Gilbert Gilb's
* implement default values for header directive closes #3804 * remove `set_default` header op and rely on "require" handler instead This has the following advantages over the previous attempt: - It does not introduce a new operation for headers, but rather nicely extends over an existing feature in the header handler. - It removes the need to specify the header as "deferred" because it is already implicitely deferred by the use of the require handler. This should be less confusing to the user. * add integration test for header directive in caddyfile * bubble up errors when parsing caddyfile header directive * don't export unnecessarily and don't canonicalize headers unnecessarily * fix response headers not passed in blocks * caddyfile: fix clash when using default header in block Each header is now set in a separate handler so that it doesn't clash with other headers set/added/deleted in the same block. * caddyhttp: New idle_timeout default of 5m * reverseproxy: fix random hangs on http/2 requests with server push (#3875) see https://github.com/golang/go/issues/42534 * Refactor and cleanup with improvements * More specific link Co-authored-by: Matthew Holt <mholt@users.noreply.github.com> Co-authored-by: Денис Телюх <telyukh.denis@gmail.com>

2020-07-17reverseproxy: Restore request's original host and header (fix #3509)Matthew Holt
We already restore them within the retry loop, but after successful proxy we didn't reset them, so as handlers bubble back up, they would see the values used for proxying. Thanks to @ziddey for identifying the cause.

2020-06-12fastcgi: Make sure splitPos handles empty SplitPath correctly (#3491)Wynn Wolf Arbor
In commit f2ce81c, support for multiple path splitters was added. The type of SplitPath changed from string to []string, and splitPos was changed to loop through all values in SplitPath. Before that commit, if SplitPath was empty, strings.Index returned 0 and PATH_INFO was set correctly in buildEnv. Currently, however, splitPos returns -1 for empty values of SplitPath, behaving as if a split position could not be found at all. PATH_INFO is then never set in buildEnv and remains empty. Restore the old behaviour by explicitly checking whether SplitPath is empty and returning 0 in splitPos. Closes #3490
