Bug ID: 62864
Summary: ProxyPass regex destination is not recognized
Product: Apache httpd-2
Version: 2.4.37
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: mod_proxy
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Within method add_pass from mod_proxy.c, there is a call to "apr_fnmatch_test"
in order to determine if cmd->path is a pattern (a regex) or a prefix
(filename).
apr_fnmatch_test does not recognize "^" or "("...")" as a pattern.
The sample from https://httpd.apache.org/docs/2.4/mod/core.html#locationmatch
is thus not recognized.
A conf like :
<LocationMatch ^/(api|truc)/$>
Require all granted
ProxyPass http://127.0.0.1:1234/$1
ProxyPassReverse http://127.0.0.1:1234/$1
</LocationMatch>
does not proxypass due to result from apr_fnmatch_test().
Changing regex to "^/(api|truc)/[\w]*$" changes result from apr_fnmatch_test()
and proxypass applies.
Note : apr_fnmatch_test() tests for a limited regex scope (posix's glob).
I added a new apr function : apr_fnmatch_test_regex()
new functions adds "^" and "(.*)" to be recognized as regex, it works as
expected for the given use-case, and maybe can be applied to other places (not
checked).
Dear Apache devs, what would be a better correction ?
br,
Alexandre.
