[Bug 62167] New: 2.4 docs should warn about ProxyPassMatch vs.

https://bz.apache.org/bugzilla/show_bug.cgi?id=62167

            Bug ID: 62167
           Summary: 2.4 docs should warn about ProxyPassMatch vs.
           Product: Apache httpd-2
           Version: 2.4.29
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Documentation
          Assignee: docs@httpd.apache.org
          Reporter: covener@gmail.com
  Target Milestone: ---

See #43513 -- this code is not in 2.4 and "most" ProxyPassMatch will define
a worker that won't be matched later.  The docs should warn in at least the
Worker section.

Should we revive the patch currently in STALLED section?

The worker is like a named connection pool. There is a special one called
the default reverse proxy worker, but sinc. it doesn't know if/when
it will ever be re-used it doesn't cache DNS or keep connections in the pool.

So when a request comes in that is proxied due to proxypassmatch, it will
consult DNS and get a new TCP Connection then destroy it at the end, unless you
go out of your way to define a worker as we tell people to do for the [P] flag
in mod_rewrite.
