accessing request parameters in sitemap
Currently the sitemap has a syntax which allows referring to matching
portions of the URL. Is there a way to refer to request arguments,
headers or session related properties directly in the sitemap?
Something like this:
<map:match pattern="doc/**">
<map:generate src="documents/{1}">
<map:parameter name="type" value="{parameter(type)}"/>
<map:parameter name="browser" value="{header(X-Browser)}"/>
</map:generate>
...
</map:match>
Thanks,

Nope. Not used entries in the Map are *not used*. :)

Am I right in saying that, in creating an action of this type, it is best
to limit the number of name,value pairs being made available as any
differing value may be enough to prevent caching even if the value is not
used in the match?

Parts of this is possible with the RequestParamAction. It would
need to be extended into a more general action to support
headers, session properties, etc and the syntax you've used
above, but the basics are there.
Take a look at org.apache.cocoon.acting.RequestParamAction.
Cheers,
Marcus

It can look like (not exactly, that's the hint):
<map:match type="request-header" pattern="X-Browser">
<map:generate src="documents/xxx">
<map:parameter name="browser" value="{1}"/>
</map:generate>
...
</map:match>
Check out matching and selection packages.
PS: It might be that some matchers are missing. If you find a miss, tell
me.
