yes there is a jkmount directive to send every requests that start with
/secure/ to tomcat.
JkMount /secure/* ajp_myhost
JkMount /secure ajp_myhost

What part of this is strange? heard of web.xml?
Yes, but what is "myprog.cgi" under Tomcat ? Is that a java webapp/servlet ?
(You are of course free to map your webapps as you wish. It is just unusual to see one
named this way, which is the reason I asked.)

Lately I am noticing that the request parameters are present when the
request hits Apache, but are dropped when request reaches tomcat.
for e.g /secure/myprog.cgi?username=user1&masteraccount=master1 (logged in
Apache), however tomcat rejects the request as
request.getParameter("username") can not be null. I have been running the
same code for ages and now I am noticing this. This is happening to
roughly
1% of the requests.
Following is my Apache config
APACHE StartServers 15
APACHE MinSpareThreads 25
APACHE MaxSpareThreads 75
APACHE ThreadLimit 512
APACHE ThreadsPerChild 32
APACHE MaxRequestWorkers 2048
APACHE MaxConnectionsPerChild 2048
APACHE AsyncRequestWorkerFactor 3
APACHE ServerLimit 64
And this is my tomcat settings
TOMCAT protocol="AJP/1.3"
TOMCAT packetSize="32000"
TOMCAT maxThreads="800"
TOMCAT processorCache="800"
TOMCAT acceptCount="300"
TOMCAT acceptorThreadCount="2"
TOMCAT minSpareThreads="80"
TOMCAT maxSpareThreads="160"
TOMCAT maxKeepAliveRequests="-1"
TOMCAT maxConnections="8192"
TOMCAT connectionTimeout="360000"
TOMCAT compression="on"
TOMCAT compressableMimeType="text/html,text/xml,text/plain"
TOMCAT redirectPort="8443"
Worker.properties config
worker.ajp_myhost.port=8009
worker.ajp_myhost.host=localhost
worker.ajp_myhost.type=ajp13
worker.ajp_myhost.retries=3

worker.ajp_myhost.connection_pool_timeout=360
Can someone please help me with 2 things.
1. Has anyone noticed request parameters dropping in transit ?
2. Help with fine tuning my Apache/Tomcat/mod_jk configs. During peak the
server will be handling 50 req/seconds.
Please let me know if you need anymore details.
Well certainly :
There is nothing in the above configuration excerpts, that leads me to
believe that a request like
"/secure/myprog.cgi?username=user1&masteraccount=master1" is even being
forwarded by Apache httpd to Tomcat.
So how does that happen ?
At the very least, there should be some "jkMount" directive somewhere in
the Apache configuration. And then, which webapp under Tomcat is
processing this request ?
Somehow the association of a "myprog.cgi" on the Apache side, and a
"request.getParameter()" on the Tomcat side sounds strange, unless there is
some piece in the middle that we are not being told about.
