order (#4726) * httpcaddyfile: Add `{vars.*}` placeholder shortcut I'm yoinking this from my https://github.com/caddyserver/caddy/pull/4657 PR because I think we should get this in ASAP for v2.5.0 along with the new `vars` directive. * Sort vars by matchers in reverse
2022-03-24httpcaddyfile: Fix #4640 (auto-HTTPS edgecase) (#4661)Francis Lavoie
Guh, this is complicated. Fixes #4640 This also follows up on #4398 (reverting it) which made a change that technically worked, but was incorrect. It changed the condition in `hostsFromKeysNotHTTP` from `&&` to `||`, but then the function no longer did what its name said it would do, and it would return hosts even if they were marked with `http://`, if they used a non-HTTP port. That wasn't the intent of it. The test added in there was kept though, because it is a valid usecase. The actual fix is to check _earlier_ whether all the addresses explicitly have `http://`, and if so we can short circuit and skip considering the rest.

2022-03-09reverseproxy: copy_response and copy_response_headers for handle_response ↵Francis Lavoie
routes (#4391) * reverseproxy: New `copy_response` handler for `handle_response` routes Followup to #4298 and #4388. This adds a new `copy_response` handler which may only be used in `reverse_proxy`'s `handle_response` routes, which can be used to actually copy the proxy response downstream. Previously, if `handle_response` was used (with routes, not the status code mode), it was impossible to use the upstream's response body at all, because we would always close the body, expecting the routes to write a new body from scratch. To implement this, I had to refactor `h.reverseProxy()` to move all the code that came after the `HandleResponse` loop into a new function. This new function `h.finalizeResponse()` takes care of preparing the response by removing extra headers, dealing with trailers, then copying the headers and body downstream. Since basically what we want `copy_response` to do is invoke `h.finalizeResponse()` at a configurable point in time, we need to pass down the proxy handler, the response, and some other state via a new `req.WithContext(ctx)`. Wrapping a new context is pretty much the only way we have to jump a few layers in the HTTP middleware chain and let a handler pick up this information. Feels a bit dirty, but it works. Also fixed a bug with the `http.reverse_proxy.upstream.duration` placeholder, it always had the same duration as `http.reverse_proxy.upstream.latency`, but the former was meant to be the time taken for the roundtrip _plus_ copying/writing the response. * Delete the "Content-Length" header if we aren't copying Fixes a bug where the Content-Length will mismatch the actual bytes written if we skipped copying the response, so we get a message like this when using curl: ``` curl: (18) transfer closed with 18 bytes remaining to read ``` To replicate: ``` { admin off debug } :8881 { reverse_proxy 127.0.0.1:8882 { @200 status 200 handle_response @200 { header Foo bar } } } :8882 { header Content-Type application/json respond `{"hello": "world"}` 200 } ``` * Implement `copy_response_headers`, with include/exclude list support * Apply suggestions from code review Co-authored-by: Matt Holt <mholt@users.noreply.github.com>

2021-08-26httpcaddyfile: Reorder some directives (#4311)Francis Lavoie
We realized we made some mistakes with the directive ordering, so we're making some minor adjustments. `abort` and `error` don't really make sense to be after other handler directives, because you would expect to be able to "fail-fast" and throw an error before falling through to some `file_server` or `respond` typically. So we're moving them up to just before `respond`, i.e. before the common handler directives. This is also more consistent with our existing examples in the docs, which actually didn't work due to the directive ordering. See https://caddyserver.com/docs/caddyfile/directives/error#examples Also, `push` doesn't quite make sense to be after `handle`/`route`, since its job is to read from response headers to push additional resources if necessary, and `handle`/`route` may be terminal so push would not be reached if it was declared outside those. And also, it would make sense to be _before_ `templates` because a template _could_ add a `Link` header to the response dynamically.

2021-01-28caddyhttp: Implement handler abort; new 'abort' directive (close #3871) (#3983)Matt Holt
* caddyhttp: Implement handler abort; new 'abort' directive (close #3871) * Move abort directive ordering; clean up redirects Seems logical for the end-all of handlers to go at the... end. The Connection header no longer needs to be set there, since Close is true, and the static_response handler now does that.
2021-01-07httpcaddyfile: Support repeated use of cert_issuer global optionMatthew Holt
This changes the signature of UnmarshalGlobalFunc but this is probably OK since it's only used by this repo as far as we know. We need this change in order to "remember" the previous value in case a global option appears more than once, which is now a possibility with the cert_issuer option since Caddy now supports multiple issuers in the order defined by the user. Bonus: the issuer subdirective of tls now supports one-liner for "acme" when all you need to set is the directory: issuer acme <dir>
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>

2020-05-06httpcaddyfile: Fix route ordering bugMatthew Holt
https://caddy.community/t/cant-get-simple-alias-to-work/7911/8?u=matt This removes an optimization where we amortized path matcher decoding. The decoded matchers were index by... position... which obviously changes during sorting. Duh. Anyway, sorting is sliiightly slower now but the Caddyfile is not really CPU-sensitive, so this is fine.
2020-04-08httpcaddyfile, caddytls: Multiple edge case fixes; add testsMatthew Holt
- Create two default automation policies; if the TLS app is used in isolation with the 'automate' certificate loader, it will now use an internal issuer for internal-only names, and an ACME issuer for all other names by default. - If the HTTP Caddyfile adds an 'automate' loader, it now also adds an automation policy for any names in that loader that do not qualify for public certificates so that they will be issued internally. (It might be nice if this wasn't necessary, but the alternative is to either make auto-HTTPS logic way more complex by scanning the names in the 'automate' loader, or to have an automation policy without an issuer switch between default issuer based on the name being issued a certificate - I think I like the latter option better, right now we do something kind of like that but at a level above each individual automation policies, we do that switch only when no automation policies match, rather than when a policy without an issuer does match.) - Set the default LoggerName rather than a LoggerNames with an empty host value, which is now taken literally rather than as a catch-all. - hostsFromKeys, the function that gets a list of hosts from server block keys, no longer returns an empty string in its resulting slice, ever.
2020-04-02httpcaddyfile: Refactor site key parsing; detect conflicting schemesMatthew Holt
We now store the parsed site/server block keys with the server block, rather than parsing the addresses every time we read them. Also detect conflicting schemes, i.e. TLS and non-TLS cannot be served from the same server (natively -- modules could be built for it). Also do not add site subroutes (subroutes generated specifically from site blocks in the Caddyfile) that are empty.
2020-03-28httpcaddyfile: Put root directive first, before redir and rewriteMatthew Holt
See https://caddy.community/t/v2-match-any-path-but-files/7326/8?u=matt If rewrites (or redirects, for that matter) match on file existence, the file matcher would need to know the root of the site. Making this change implies that root directives that depend on rewritten URIs will not work as expected. However, I think this is very uncommon, and am not sure I have ever seen that. Usually, dynamic roots are based on host, not paths or query strings. I suspect that rewrites based on file existence will be more common than roots based on rewritten URIs, so I am moving root to be the first in the list. Users can always override this ordering with the 'order' global option.

2020-01-22httpcaddyfile: Update directive docs; put root after rewriteMatthew Holt
2020-01-17httpcaddyfile: Move redir before rewriteMatthew Holt
Using rewrite is like saying, "I accept this request, but I just need to act on it as if it came in differently." Whereas redir implies more of, "I reject this request, send it to me differently, then I will process it." Makes sense for it to come before rewrites. This can always be changed using the 'order' global option if needed.
2020-01-16httpcaddyfile: Fix nested blocks; add handle directive; refactorMatthew Holt
The fix that was initially put forth in #2971 was good, but only for up to one layer of nesting. The real problem was that we forgot to increment nesting when already inside a block if we saw another open curly brace that opens another block (dispenser.go L157-158). The new 'handle' directive allows HTTP Caddyfiles to be designed more like nginx location blocks if the user prefers. Inside a handle block, directives are still ordered just like they are outside of them, but handler blocks at a given level of nesting are mutually exclusive. This work benefitted from some refactoring and cleanup.
2020-01-16httpcaddyfile: Replace 'handler_order' option with 'order'Matthew Holt
This allows individual directives to be ordered relative to others, where order matters (for example HTTP handlers). Will primarily be useful when developing new directives, so you don't have to modify the Caddy source code. Can also be useful if you prefer that redir comes before rewrite, for example. Note that these are global options. The route directive can be used to give a specific order to a specific group of HTTP handler directives.
