* WIP: Implement HTTPS interception detection by Durumeric, et. al.
Special thanks to @FiloSottile for guidance with the custom listener.
* Add {{.IsMITM}} context action and {mitm} placeholder
* Improve MITM detection heuristics for Firefox and Edge
* Add tests for MITM detection heuristics
* Improve Safari heuristics for interception detection
* Read ClientHello during first Read() instead of during Accept()
As far as I can tell, reading the ClientHello during Accept() prevents
new connections from being accepted during the read. Since Read() should
be called in its own goroutine, this keeps Accept() non-blocking.
* Clean up MITM detection handler; make possible to close connection
* Use standard lib cipher suite values when possible
* Improve Edge heuristics and test cases
* Refactor MITM checking logic; add some debug statements for now
* Fix bug in MITM heuristic tests and actual heuristic code
* Fix gofmt
* Remove debug statements; preparing for merge
* fixing panic when root is symlink
checking root path is a symlink before os.Stat which panics
* fixing formatting
* adding test to verify symlink root path check
* fixing typo
* Add request placeholder support for querying request cookies.
This adds the ability to query the request cookies for placeholders
using the syntax "@cookiename".
For example, this would allow rewriting based on a cookie:
rewrite {
if @version is 'dev'
to /dev/index.html
}
* Switch cookie special char from @ to :
* Switch special char for cookies from : to ~
* Fix data race for max connection limiting in proxy directive.
The Conns and Unhealthy fields are updated concurrently across all active
requests. Because of this, they must use atomic operations for reads and
writes.
Prior to this change, Conns was incremented atomically, but read unsafely.
Unhealthly was updated & read unsafely. The new test
TestReverseProxyMaxConnLimit exposes this race when run with -race.
Switching to atomic operations makes the race detector happy.
* oops, remove leftover dead code.
* Use new subdirectives and flatten rolling config
* Set default rotate config
* Set default rolling config (hopefully) errwhere
* Make private
* Flatten errors directive and remove c.IncrNest()
* Don't skip first error log roller subdirective we see
* Remove hadBlock
* Try lumberjack import
* Unname import
The standard lib pprof library doesn't set its own Content-Type header
properly. If pprof is used with gzip, the index endpoint will be
interpreted as a .gz file; so we force its hand and set the header.
* proxy: use a new context for the outgoing request

* Generate meta elements from useful front matters.
Limited to the default template and specific elements.
* Rerun gofmt
* Add "keywords" and remove "language" to/from the list of meta tags.
* Add a simple positive list test for the meta tag generation.
* Move the meta tag list to a var at the begin of the file.
Seperate the Meta tags from the other front matters:
- Don't override user settings with name `meta`
- Cleaner Code.
* Remove the uneccessary `[:]` in the []Bytes to String casting.
@mholt was right ;)
* One minor refinement. Combining two statements.
Because of this commit(6e36811c37399d60cbce587b7c48e611009c5aec) on go tip,
it will probe the request's body to determine whether to use chunked transfer
encoding which trailers depend on it.
So we just offer a non empty body to make trailers work.

* Add {whenISO} to record timestamp in ISO 8601 format in UTC.
ISO 8601 is the standard time format and is easy to parse.
This change assumes users desiring ISO 8016 generally prefer UTC for simplicity.
This results in {whenISO} to be significantly shorter than {when}:
{when} = "02/Jan/2006:15:04:05 +0000"
{whenISO} = "2006-01-02T15:04:12Z"
Add unit test to verify both, as there was no unit test for {when}.
* Rename {whenISO} to {when_iso}
If only one upstream is defined we don't need to buffer the body.
Instead we directly stream the body to the upstream host,
which reduces memory usage as well as latency.
Furthermore this enables different kinds of HTTP streaming
applications like gRPC for instance.
If a site owner protects a path with basicauth, no need
to use the Authorization header elsewhere upstream, especially since it
contains credentials.
If this breaks anyone, it means they're double-dipping. It's usually
good practice to clear out credentials as soon as they're not needed
anymore. (Note that we only clear credentials after they're used,
they stay for any other reason.)
