Hello,

I've asked this question on users list, but no one answered. I've also 
tried to check in source code if it is a bug, but the caching stuff is 
to complex for me. Maybe you can help me.

Hello

I have problem with caching of xsl stylesheets. Here is a simplified
example, I have layout.xsl pipeline:

<map:match pattern="layout.xsl">
   <map:select type="host">
     <map:when test="foo">
       <map:generate src="layout_foo.xsl"/>
     </map:when>
     <map:otherwise>
       <map:generate src="layout_bla.xsl"/>
     </map:otherwise>
   </map:select>
   <map:serialize type="xml"/>
</map:match>

When I try it on browser it works correctly, and depending on host name
I see different layout_*.xsl files. This pipeline I include in a
stylesheet named test.xsl:

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:include href="cocoon:/layout.xsl"/>
</xsl:stylesheet>

Ant test.xsl is used in another pipeline:

<map:match pattern="test">
   <map:generate src="test.xml"/>
   <map:transform type="xslt" src="test.xsl"/>
   <map:serialize type="xml"/>
</map:match>

This time, when I try it in browser the request is cached and output
does not vary on host name. For example i try:
http://foo.localhost/test -> Foo layout (ok)
http://bla.localhost/test -> Foo layout (but should be Bla layout)

When i restart server and first try:
http://bla.localhost/test -> Bla layout (ok)
http://foo.localhost/test -> Bla layout (but should be Foo layout)

Simply speaking first request is cached. I've tried setting pipeline to
"noncaching" and transformer to "use-request-parameters" but with no
success (sitemap included at the end of this mail). The only way I can
solve this is turning off "use-store" for transformers in cocoon.xconf,
but I think this would reduce performance.

The question is: Am I doing something wrong? Or is it a bug in
stylesheets caching?

My sitemap is:
