mod_ssl: Fix a possible crash during access control checks if a
non-SSL request is processed for an SSL vhost (such as the
"HTTP request received on SSL port" error message when an 400
ErrorDocument is configured, or if using "SSLEngine optional").
PR 37791. [Rüdiger Plüm, Joe Orton]
*) SECURITY: CVE-2005-3352 (cve.mitre.org)
mod_imagemap: Escape untrusted referer header before outputting
in HTML to avoid potential cross-site scripting. Change also
made to ap_escape_html so we escape quotes. Reported by JPCERT.
[Mark Cox]
*) mod_proxy_ajp: Flushing of the output after each AJP chunk is now
configurable at runtime via the 'flushpackets' and 'flushwait' worker
params. Minor MMN bump. [Jim Jagielski]
*) mod_proxy: Fix incorrect usage of local and shared worker init.

failures, instead of APR_EGENERAL.

output of 'httpd -V'. [William Rowe]
*) http: If a connection is aborted while waiting for a chunked line,
flag the connection as errored out. [Justin Erenkrantz]

*) mod_proxy: Fix KeepAlives not being allowed and set to
backend servers. PR 38602. [Ruediger Pluem, Jim Jagielski]
*) mod_proxy: If we get an error reading the upstream response,
close the connection. [Justin Erenkrantz, Roy T. Fielding,
Jim Jagielski, Ruediger Pluem]
*) mod_proxy_ajp: Support common headers of the AJP protocol in responses.
PR 38340. [Aleksey Pesternikov <apesternikov yahoo.com>]
*) mod_proxy_balancer: Do not overwrite the status of initialized workers and
respect the configured status of uninitilized workers when creating a new
child process. [Ruediger Pluem]
*) mod_proxy_ajp: Crosscheck the length of the body chunk with the length of
the ajp message to prevent mod_proxy_ajp from reading beyond the buffer
boundaries and thus revealing possibly sensitive memory contents to the
client. [Ruediger Pluem]
*) Ensure that the proper status line is written to the client, fixing
incorrect status lines caused by filters which modify r->status without
resetting r->status_line, such as the built-in byterange filter.
[Jeff Trawick]
*) mod_speling: Stop crashing with certain non-file requests. [Jeff Trawick]
*) mod_cache: Make caching of reverse proxies possible again. PR 38017.
[Ruediger Pluem]
*) Modify apr[util] .h detection to avoid breakage on VPATH builds
using Solaris make (amoung others) and avoid breakage in ./buildconf
when srclib/apr[-util] are symlinks rather than directories proper.
[William Rowe]
*) Chunk filter: Fix chunk filter to create correct chunks in the case that
a flush bucket is surrounded by data buckets. [Ruediger Pluem]

*) Remove support for 'On' and 'Off' for AuthBasicProvider and
AuthDigestProvider. [Joshua Slive, Justin Erenkrantz]
*) Add in new UseCanonicalPhysicalPort directive, which controls
whether or not Apache will ever use the actual physical port
when constructing the canonical port number. [Jim Jagielski]

handling of MKCOL.
