Can anyone tell me which error code would show up when an like the one
mentioned in this thread occurs? Would it be 502, or 504? Or something
different?
Thanks,
Chris.

So has nobody else experienced the same problem? Is this a bug?
Should I provide more information? Where can I find the error codes
for proxy ajp?

Hello,
I'm having a problem with mod_proxy_ajp, I am receiving the following

The following are my configuration files:
httpd.conf:
...

</VirtualHost>
In my tomcat server.xml, I have:
<!-- Define an AJP 1.3 Connector on port 8009 -->
<Connector address="url"
port="8009"
enableLookups="false"
protocol="AJP/1.3"
minSpareThreads="20"
maxSpareThreads="200"
maxThreads="1024"
connectionTimeout="600000"
/>
and my proxy_ajp.conf:
ProxyPass /order ajp://url:8009/order
ProxyPass /dwr ajp://url:8009/dwr
The error messages come up intermittently maybe 5 times a day
(although the ajp_check_msg_header() is a new one). I believe what
happens is the user gets to the secure checkout page, hits the order
button and then the error shows up in the log file, but what the user
gets is a blank page instead of the order confirmation page. Could
this be an SSL thing?
I've been through the mailing lists and seen some advice for people
who are using the worker mpm, but nothing when using prefork.
Can anyone please, let me know what is going on (I'd like to
understand why I get the error messages) and what to do prevent the
error from coming up.
Thanks all for your consideration it is appreciated,
Chris.
