A few comments first: 1) Try to avoid proxying inside a <Location> block, unless you have a good reason to. You have more control in the vhost context over the URI paths. 2) Stop using the 2.2 authz directives, those have been deprecated for over a decade
Now, your ProxyPassReverse is effectively: ProxyPassReverse /host1/ http://192.168.4.12/ This means that if the backend issues a Location: header to something other than /host1/, you won't catch it. You need handle a more generic URI scheme. On Tue, 4 Oct 2022 at 06:02, Duke Nguyen <duke.li...@gmx.com> wrote: > Hello everyone, > > I have an issue with the proxy and subdirectory on httpd.
