If several directories are given in a UserDir directive, only files in the first existing one are checked. If the file is not found there, the other possible directories are not checked.

In 'ap_proxy_cookie_reverse_map', iterate over each token of the 'Set-Cookie' header field in order to avoid updating the wrong one.

This could happen if the header field has something like 'fakepath=foo;path=bar". In this case fakepath would be updated instead of path.


We don't need regex anymore in order to parse the field values and 'ap_proxy_strmatch_domain' and 'ap_proxy_strmatch_path' are now useless. (and should be axed IMHO)

                 ap_send_error_response

While debugging PR 61860 I found a chain of events
that leads to duplicate headers in the HTTP response
if Header always set is used in the httpd's config.

As far as can understand, mod_headers uses err_headers_out
when dealing with the 'always' setting, since it is expected
to be preserved even on error. The current code seems
to correctly preserve the important headers like Location
(happening before the bit of code that changed), but then
it swaps headers_out with err_headers_out and clears
err_headers_out. My understanding is that this will cause
mod_headers, if called again, to re-insert the headers
set via 'always' again in err_headers_out, leading to a
duplication in the response. So far I managed to reproduce this
only with the specific use case outlined by the PR, but
there might be more.

r1831585 was added to the test suite for PR 61860,
(marked as TODO), and now it seems to pass as expected.

Since this part of the codebase has been working fine
for years I was reluctant to change it, but it seems
the right change to me. I didn't run into any regression
while testing this change (including running the test suite),
but as always I'd be glad to get feedback from a more expert
eye. If I missed a clear regression I'll make sure to
add it to the test suite as part of the follow up.

Otherwise, when BalancerPersist is enabled, we might fail (re)starting with a
saved slotmem if a BalancerMember was renamed (e.g. PR 62308's port change).
This is because the renamed member is considered a new one, while the old name
still reserves a slot, so we end up missing one room. The overall number of
members does not change so the sizes check succeeds thus the persisted slotmem
is not invalidated. Yet the slomem is not really compatible.

By clearing inuse flags, we still allow for slots to be reused if their index
did not change (thanks to ap_proxy_find_balancershm() and slotmem_fgrab() at
the given index), but will also invalidate renamed slots which don't match the
index. We now have the correct behaviour by slot and the server (re)starts in
any case.

Since persistent files are also reused on stop/start, we must ensure that
they match the same descriptor when reused on the next startup, so add it
to integrity metadata.

Also, the descriptor being the first field in the SHM, we don't need to
copy on the stack it in several places, and can handle it as a pointer.

Don't try to attach SHMs on startup, they might be from a previous crash and
prevent the server to start (on failure to reuse it).

On mpm_winnt though, the pre/post_config() phases are re-run in child process,
and the parent process already created the SMs, so they must be attached there.

r1831394 is the right follow to r1830800 to preserve "inherited" slotmems in
