Changes between 1.2.21 and 1.2.22
Native
Refactor line endings logging to make it correct for all platforms and webservers. (mturk)
Added command line windows make files. (mturk)
Allow fail_on_status directive to be multi line. (mturk)
42076: Fix name of new option from ForwardCertChain to ForwardSSLCertChain as documented. (rjung)
Docs: Fix a couple of typos, change format of a few tables, fix links to news pages. (rjung)
Fix correct URL for TC 6 examples in new IIS rewrite.properties configuration example file. (rjung)
Add svn properties to several files. (rjung)
Add TC 6 examples to uriworkermap.properties in config examples. (rjung)
Allow multiple status codes for fail_on_status directive. The status codes can be delimited by space or comma characters. (mturk)
IIS. Added pcre like regular expressions for url rewrite rules. (mturk)
41922: Apache 1.3. Enable JkEnvVar. (mturk)
Apache. Add --enable-flock configure parameter for explicit compilation of faster flock() system calls for OS supporting those calls. By default the fcntl system call for locking will be used that is a little bit slower but it can work on NFS mounted volumes as well. (mturk)
41562: Add Debug logging for read from client in ISAPI Redirector. Contributed by Tim Whittington. (mturk)
Apache. Add ForwardSSLCertChain JkOption. Contributed by Patrik Schnellmann. (mturk)
IIS. Do not forbid access to web-inf or meta-inf if there is no mapped worker. This allows to have resource with those names that are outside mapped contexts. (mturk)
Apache. Use process id for creating shared memory name and delete shared memory and shared memory lock files on exit. (mturk)
IIS. Fix Keep-Alive regression introduced in 1.2.21. (mturk)
Delete unused check for empty init_map during startup. (rjung)
41770: Fix startup error if no JkWorkersFile is used. (rjung)
Use JK_TRUE/JK_FALSE instead of OK/!OK as return values in init_jk(). (rjung)
Minor adjustments to apache startup log messages (when to use STDERR, remove deprecated NOERRNO flag, shm warning and warnings for usage of default files). (rjung)
Replace APR precompiler directive by httpd mpm_query to detect MPM threading. Add a debug log message about auto-detected pool size. (rjung)
Make MMN check easier to understand and a little more precise (for new ap_get_server_banner()/ap_get_server_description()). We use the new API only for Apache httpd 2.3. This way our binaries are not tightly coupled to a minor 2.0 version, and we don't use ap_get_server_banner() any way. (rjung)
Use the full description string ap_get_server_description() instead of the truncated info from ap_get_server_banner(), because this info gets used internally (status worker display and ajp14 backend communication) and is not send back to the normal user. (rjung)
41757: Document the "--enable-prefork" flag of configure. (rjung)
Enhance log messages for failures when parsing attribute maps. (rjung)
Correct log message during worker initialization, in case remote host could not be resolved. We logged the default host name "localhost" instead of the configured one. (rjung)
41770: Fix the second part of the bug: local_worker and local_worker_only is missing from the list of deprecated attributes (and not supported either), so prevents the web server from startup. (rjung)
Changes between 1.2.20 and 1.2.21

CVE-2007-0774 : A denial of service and critical remote code execution vulnerability. Caused by buffer overflow in map_uri_to_worker() when URL were longer that 4095 bytes. Reported by ZDI (www.zerodayintiative.com). Please note this issue only affected versions 1.2.19 and 1.2.20 of the Apache Tomcat JK Web Server Connector and not previous versions. Tomcat 5.5.20 and Tomcat 4.1.34 included a vulnerable version in their source packages. Other versions of Tomcat were not affected.
Check the worker. parameters and don't start if the parameter is not a valid one. (jfclere)
41439: Allow session IDs to get stripped off URLs of static content in Apache by adding JkStripSession directive (configurable per vhost). (mturk)
Change semantics of empty defaults for JkEnvVar variables. Until 1.2.19: not allowed. In 1.2.20: send variables as empty strings, if neither set to non empty in config, nor during runtime. Starting with 1.2.21: If config has no second argument only send variable if set (even when set to empty string) during runtime. Allows good combination with condition attribute in tomcat access log. (rjung)

JkStatus: Allow lb sub workers in error state to be marked for recovery administratively from the status worker. (rjung)
Load Balancer: Do not try to recover multiple times in parallel. Use additional runtime states "PROBE" and "FORCED". (rjung)
JkStatus: Improve data synchronization between different processes. (rjung)
41381: Fix segfault in feature fail_on_status (wrong order of log arguments). Patch by Juri Haberland. (rjung)
