According to the HAProxy 1.8 documentation:
http://cbonte.github.io/haproxy-dconv/1.8/configuration.html#7.1
~~~~
- "dir" : subdir match : check that a slash-delimited portion of the
contents exactly matches one of the provided string patterns.
This may be used with binary or string samples.
[...]
- subdir match (-m dir) : the patterns are looked up inside the extracted
string, delimited with slashes ("/"), and the ACL matches if any of them
matches.
~~~~
It is unclear if the math happens with the pattern "rooted" (i.e. the
pattern must also be a prefix) or not?
More exactly given an ACL of the form:
~~~~
acl subdir path() -m dir -- /test
~~~~
Which of the following would it match:
* `/test` -- I would expect yes;
* `/test/whatever` -- I would expect yes;
* `/whatever/test` -- I would expect no, however it does (at least in 1.8.14)...
Thanks,
Ciprian.
