Sharun,
Marking OT because this is almost certainly not a Tomcat issue, but
Cocoon configuration or something else.

I'm on Cocoon 2.1.11. You and me both need to upgrade badly! I also
happen to be using Tomcat 6.0.32 in production.

So... that's how things are supposed to work, so that's not a problem.

Exactly what does your configuration look like? We have pipelines like
this:
<map:match pattern="report/full.xml">
<map:generate
src="{global:base-url}/report.xml.do;jsessionid={request:requestedSessionId}?id={request-param:id}"
/>
<map:transform
src="{global:stylesheet-url}/responses-to-cinclude.xsl">
<map:parameter name="base-url" value="{global:base-url}" />
<map:parameter name="include-foo"
value="{request-param:include-foo}" />
</map:transform>
<map:transform
src="{global:stylesheet-url}/resources-to-cinclude.xsl">
<map:parameter name="rsid-param" value="{request-param:rsid}" />
</map:transform>
<map:transform type="cinclude" />
<map:serialize type="xml" />
</map:match>
The above {request-param:foo} settings seem to work reliably for me.
All of our requests are GET... all POST requests are handled by
non-Cocoon-based code.

That's certainly strange. Have you tried observing the HTTP traffic
using something like fiddler, LiveHTTPHeaders, etc. to see what the
client is sending?

Request parameters are read from POST requests the first time any of
the ServletRequest.getParameter* family of methods are called. I'm not
entirely sure when GET parameters are parsed... probably at the same
time. If you use {request-param:foo}, that will translate (eventually)
into a call to ServletRequest.getParameter("foo"), so this should work
consistently.
