Good.
Shared mutable static fields are generally a bad idea.
Even private fields are better made final if possible.

OK.
<soapbox>
I'm always wary about numbers in code - anything other than +/-1 or 0
has the potential to be wrong or misunderstood, especially if it is
not documented.
There was recent Tomcat bug to do with timeouts where there was a bare
number 100000 or was it 1000000? The meaning of number was/is not
documented, so it's not trivial to check if it's correct.
Much easier to understand would be something like
#define 100MILLISECS_AS_MICROSECS 100000
I'd like to see all numbers (apart from 0/1) expressed as defines, but
that is perhaps asking too much.
Helps document the code, and makes it much easier to change later, as
one can distinguish numbers with the same value but different
functions.

Fixed in r752629 +r752644. The whole JavaDocs are a mess though, they
are more or less only stubs. The Java parts of the connectors release
would need a bit of love.

Initial size, the array will automatically grow, if needed. I first
introduced a defined constant for that, and then changed my mind and
switched to using "0" as the initial size. Arrays and tables resize
automatically and this is not a critical code path w.r.t. performance.

Default + automatic resize. See above.

Apache Tomcat Connectors snapshot 1.2.28-dev-752124 available for
testing.
Posted by Rainer Jung <ra...@kippdata.de>.
Hi all,
version 1.2.28 of mod_jk is approaching its release. A code snapshot
(revision 752124) is available at:
http://tomcat.apache.org/dev/dist/tomcat-connectors/jk/source/jk-1.2.28-dev/
Please join us in ensuring the quality of the forthcoming release by
testing this snapshot. The source archives are in the same format as a
release download, so easy to build. We also provide some binaries at
http://tomcat.apache.org/dev/dist/tomcat-connectors/jk/binaries/
Depending on your feedback we plan to tag the release at the end of this
week or next week. If you find any bugs while using this snapshot,
please fill in the Bugzilla Bug Report or send an e-mail to Tomcat
Developers List. When entering bug use the following link:
http://issues.apache.org/bugzilla/enter_bug.cgi?product=Tomcat%20Connectors
Notice:
Please do not use this snapshot for production.
It is meant to be used for testing purposes only!
The release will contain some bug fixes and improvements:
Features/Improvements
---------------------
General:
- Add new property error_escalation_time for LB workers
to fine tune escalation of local errors to global errors.
- If the sticky session affinity mark contains a dot, an LB
treats the part after the dot as the domain name.
This allows to have full node session affinity with domain failover.
- Allow AJP13 worker ports lower or equal to 1024.
- Move shm locking into the data pull and push methods.
- Deprecate JNI workers.
Apache:
- Add more environment variables to overwrite request information.
Useful in case a proxy is in front of Apache and sends us original
request information e.g. via custom headers.
IIS:
- Improve support for multiple Application Pools
- Update uriworkermap.properties file on a regular interval.
This requires both worker_mount_reload and watchdog_interval
to be defined.
- Remove obsolete entries from registry file.
Status-Worker:
- Allow changing worker address and port of AJP workers.
The address is resolved on next request for that worker.
- Include error time in display.
- Do not redirect to the show or list page, if an error occured
during an action.
- Allow update actions to show error messages in the result page.
- Remove redundant port information from worker display.
Rename address column and remove its explanation from the legend.
- Optimize forced uriworkermap.properties reload.
Docs:
- Add a new HowTo page about reverse proxies.
- Clarify IIS URL rewrite feature.
- Clarify relation between socket_timeout and socket_connect_timeout.
Fixes
-----
- JkWatchogInterval used a wrong interval calculation causing a
10 times higher watchdog interval then configured for Apache 2.x.
- Fix forced recovery in combination with local error states.
- Fix crash in text display format of status worker.
- Set global worker state to error in L, when we reach
max_reply_timeouts, or fail_on_status triggered hard error.
- Show - Edit - Show in status worker always ends in single
lb member show, even when started from all members lb show.
- Fix use of wildcards in sub worker names were broken for
update actions of status worker.
- BZ 46763: Survive the log mutex in Apache 2.x during graceful restart.
- BZ 46416: Fix building Apache 2.x on Windows: Include mstcipip.h
even if apr doesn't include it.
- BZ 46734: Fix broken links in documentation.
- BZ 46579: Use local environment table instead environment
variables for setting the JKISAPI_PATH and JKISAPI_NAME.
- Missing define for MAX_PATH on Netware
- BZ 46352: Fix crash in Apache, when using SetHandler jakarta-servlet
in VHost without any JkMount.
- BZ 46169: Backport use_server_errors mount extension to Apache 1.3.
- Add 2008 news to main documentation page and documentation menues.
Furthermore there have been some minor code refactorings in the load
balancer error handling.

Rainer,
The connectors FAQ (http://tomcat.apache.org/connectors-doc/miscellaneous/faq.html
)states:
mod_jk works well with Apache 2.2. You need a binary module compiled
for version 2.2 of the Apache web server. A binary compiled for
version 2.0 will not work.
Important parts of the functionality of mod_jk have been reimplemented
as Apache httpd modules mod_proxy_ajp and mod_proxy_balancer. These
are part of the standard distributoin of Apache 2.2. The new modules
do not contain all features of mod_jk, but you get them automatically
with every Apache 2.2.
Is there anywhere a description of what mod_jk does that is NOT done
by mod_proxy_ajp and mod_proxy_balancer?
Also, does this release imply a corresponding release of mod_jk?
Thanks,
Ken

Please join us in ensuring the quality of the forthcoming release by
testing this snapshot. The source archives are in the same format as a
release download, so easy to build.
The last release is already 10 months old and there were important
changes in the meantime. We hope we can make you interested in testing
by the following list of improvements:
Features/Improvements
---------------------
General:
- New optional watchdog thread (Apache/IIS) doing internal maintenance
(idle connection checks, backend probing).
See JkWatchdogInternal (Apache) and watchdog_interval (IIS).
- Added session_cookie and session_path for configuring session
identifiers.
- Add extension attributes to uri worker map (Apache/IIS). Allowed are:
- reply_timeout
- active/disabled/stopped
- fail_on_status
- use_server_errors
which can now be used per mount and not only per worker.
- New communication configuration directives:
- socket_connect_timeout
- connection_acquire_timeout
- retry_interval time
- connection_ping_interval, ping_timeout and ping_mode
- Allow using web server error pages.
- Automatically determine needed shm size
Apache:
- Allow dynamic setting of reply timeout using the environment
variable JK_REPLY_TIMEOUT.
IIS:
- Basic support for multiple Webs in one Application Pool
- Basic support for multiple Application Pools
- Use environment variables JKISAPI_PATH (Full path to the ISAPI
Redirector) and JKISAPI_NAME (Name of the ISAPI Redirector dll
without extension) in attribute values of the redirector .properties
file (Example: log_file=$(ISAPI_PATH)\$(ISAPI_NAME).log)
- New attribute error_page which can contain a full URL used
as a redirect URL when an error occurs. Any "%d" in error_page will be
replaced by the HTTP status code of the error.
- New boolean attribute enable_chunked_encoding to allow chunked
encoding of HTTP responses. This is currently considered experimental.
To be able to use it, you need to build the isapi redirector with
an additional define "ISAPI_ALLOW_CHUNKING".
- Use raw headers instead of CGI headers. Fixes problem
"underscore=dash" problem in header names. This is currently
considered experimental.
To be able to use it, you need to build the isapi redirector with
an additional define "USE_RAW_HEADERS".
- Improved IIS event detection. This also imporoves IIS 5.1
compatibility. It is currently considered experimental.
To be able to use it, you need to build the isapi redirector with
an additional define "AUTOMATIC_AUTH_NOTIFICATION".
Status-Worker:
- Add manageability and statistics counters for simple ajp workers and
ajp lb members.
- Add display of seconds since last statistics reset and
access and transfer rates.
- Add "dump" action.
- Allow showing only a single member for a load balancer.
- Include server local time in output.
- Improve XSS hardening.
- Layout changes.
Build:
- Improve Cygwin build.
- Don't use post httpd 2.2.0 API functions when building with new
--enable-api-compatibility configure switch.
- Use correct ld flags provided by apxs when building module.
Prevents some crashes on AIX for httpd 1.3 module.

Apache Tomcat Connectors snapshot 1.2.28-dev-752124 available for
testing.
Posted by Rainer Jung <ra...@kippdata.de>.
Hi all,
version 1.2.28 of mod_jk is approaching its release. A code snapshot
(revision 752124) is available at:
http://tomcat.apache.org/dev/dist/tomcat-connectors/jk/source/jk-1.2.28-dev/
Please join us in ensuring the quality of the forthcoming release by
testing this snapshot. The source archives are in the same format as a
release download, so easy to build. We also provide some binaries at
http://tomcat.apache.org/dev/dist/tomcat-connectors/jk/binaries/
Depending on your feedback we plan to tag the release at the end of this
week or next week. If you find any bugs while using this snapshot,
please fill in the Bugzilla Bug Report or send an e-mail to Tomcat
Developers List. When entering bug use the following link:
http://issues.apache.org/bugzilla/enter_bug.cgi?product=Tomcat%20Connectors
Notice:
Please do not use this snapshot for production.
It is meant to be used for testing purposes only!
The release will contain some bug fixes and improvements:
Features/Improvements
---------------------
General:
- Add new property error_escalation_time for LB workers
to fine tune escalation of local errors to global errors.
- If the sticky session affinity mark contains a dot, an LB
treats the part after the dot as the domain name.
This allows to have full node session affinity with domain failover.
- Allow AJP13 worker ports lower or equal to 1024.
- Move shm locking into the data pull and push methods.
- Deprecate JNI workers.
Apache:
- Add more environment variables to overwrite request information.
Useful in case a proxy is in front of Apache and sends us original
request information e.g. via custom headers.
IIS:
- Improve support for multiple Application Pools
- Update uriworkermap.properties file on a regular interval.
This requires both worker_mount_reload and watchdog_interval
to be defined.
- Remove obsolete entries from registry file.
Status-Worker:
- Allow changing worker address and port of AJP workers.
The address is resolved on next request for that worker.
- Include error time in display.
- Do not redirect to the show or list page, if an error occured
during an action.
- Allow update actions to show error messages in the result page.
- Remove redundant port information from worker display.
Rename address column and remove its explanation from the legend.
- Optimize forced uriworkermap.properties reload.
Docs:
- Add a new HowTo page about reverse proxies.
- Clarify IIS URL rewrite feature.
- Clarify relation between socket_timeout and socket_connect_timeout.
Fixes
-----
- JkWatchogInterval used a wrong interval calculation causing a
10 times higher watchdog interval then configured for Apache 2.x.
- Fix forced recovery in combination with local error states.
- Fix crash in text display format of status worker.
- Set global worker state to error in L, when we reach
max_reply_timeouts, or fail_on_status triggered hard error.
- Show - Edit - Show in status worker always ends in single
lb member show, even when started from all members lb show.
- Fix use of wildcards in sub worker names were broken for
update actions of status worker.
- BZ 46763: Survive the log mutex in Apache 2.x during graceful restart.
- BZ 46416: Fix building Apache 2.x on Windows: Include mstcipip.h
even if apr doesn't include it.
- BZ 46734: Fix broken links in documentation.
- BZ 46579: Use local environment table instead environment
variables for setting the JKISAPI_PATH and JKISAPI_NAME.
- Missing define for MAX_PATH on Netware
- BZ 46352: Fix crash in Apache, when using SetHandler jakarta-servlet
in VHost without any JkMount.
- BZ 46169: Backport use_server_errors mount extension to Apache 1.3.
- Add 2008 news to main documentation page and documentation menues.
Furthermore there have been some minor code refactorings in the load
balancer error handling.

Good Morning James-
Do you see the same behaviour with the headers or do you see this behaviour with just the body?
With regards to the body
what happens if you post a content-type to something other than html
http://myuminfo.umanitoba.ca/help.asp?eve=2&fid=254
Thanks,

Hi Mladen,
We have been having a problem with the AJP connector for a while, sometimes
it gets stuck on the begin of receiving the post body until AJP connector
read timeout, don't know if it's related to mod_jk or apached httpd server
or Client side browser issues.Because of the missing body part, it causes
the JSP/Servlet programs fail to get the parameters, following is my
finding for your reference :
1. if we set keepAliveTimeout to 15 seconds then it occurs 400 times/day in
average.
2. if we set keepAliveTimeout to 5 seconds then it occurs 900 times/day in
average.
3. if we disbale the keepAlive in Apache httd server then it occurs 66
times/day only.
It looks like it related the KeepAlive issue, but I learned from another
thread I post on the Tomcat User mail-list, said that this problem can be
resolved by using Tomcat http connector instead, Please have a check.
Thanks.
James Wang.

- Improved IIS event detection. This also imporoves IIS 5.1
compatibility. It is currently considered experimental.
To be able to use it, you need to build the isapi redirector with
an additional define "AUTOMATIC_AUTH_NOTIFICATION".
Status-Worker:
- Add manageability and statistics counters for simple ajp workers and
ajp lb members.
- Add display of seconds since last statistics reset and
access and transfer rates.
- Add "dump" action.
- Allow showing only a single member for a load balancer.
- Include server local time in output.
- Improve XSS hardening.
- Layout changes.
Build:
- Improve Cygwin build.
- Don't use post httpd 2.2.0 API functions when building with new
--enable-api-compatibility configure switch.
- Use correct ld flags provided by apxs when building module.
Prevents some crashes on AIX for httpd 1.3 module.
Docs
----
- Various minor additions.
Fixes
-----
- BZ 36385: Add missing prepost cping/cpong directly after connect
in case prepost cping is used, but no connect cping.
- BZ 44116: Fix handling of multiple JSESSIONID cookies.
- BZ 44147: Multiple load balancing workers problem.
- BZ 44738: Fix merging of JkOption ForwardURI* between virtual hosts.
- BZ 45026: For Apache httpd 2.x add "Unknown Reason" as the
reason phrase, if we get an empty one from the backend.
Otherwise httpd 2.x returns status 500.
- BZ 45812: Add done() service method that causes sending EOS bucket
for Apache httpd 2.x. This allows filter chain to work properly.
- Improved thread safety on some platforms, especially AIX
- Fix IIS memory corruption due to parallel initialization by
multiple threads.
- Set lb_factor instead of distance in status worker.
- JkAutoAlias does not work in combination with JkMountCopy if there
are no JkMount in virtual host.
- Make dynamic URI map reloading atomic and free memory not needed
any longer.
- Always send initial POST packet even if the client disconnected.
Furthermore there have been a couple of additional code refactorings.
