Thank's; it is a step. I'm not so familiar with JXPath (but really familiar with XSLT and Xpath) The sample in http://wiki.apache.org/cocoon/InputModules {request:cookies[name='lastVisit']/@value} suggest me to try a similar expression ({request:headers[name='xxx']/@value}) but cookies is an array of cookie objects where headers is an enumerator I see in the code of the RequestGenerator how this enumerator could be used, but I can't see how this could be used in an expression like ({request:headers[1]})
I will continue to search the solution, but help is welcome.
