How to get the request parameters in a transformer?

[Davide]

Hi!

I'm creating a transformer to modify link elements in an xhtml page (i.e. 
a, img, link....);
I need to transform links from relative to absolute, so i need to know the 
url of the last request to add it to the link...

this is the sitemap:

<map:match pattern="aggregate">
        <map:act type="auth-protect">
                <map:parameter name="handler" value="navigation"/>
                <map:parameter name="use-request-parameters" value="true"/>
                <map:generate type="serverpages" src="xsp/mcnavigator.xsp"/>
                <map:transform type="cinclude"/>
                <!-- adjust the tags position to create an xhtml page -->
                <map:transform type="xslt" src="style/mcnavigator.xsl"/>
                <!-- My Transformer!!! -->
                <map:transform type="AbsoluteLinkTransformer"/>
                <map:serialize type="xml"/>
                </map:act>                        
        </map:match>
</map:match>
When i call the aggregate pipeline i pass it a parameter link in wich i put 
the url of the page i want to retreive (e.i. aggregate?link=www.w3.org), 
so... how to get my link parameter in the transformer?

thanks a lot, best regards.
