Change the URL to 'detail/html2pdf?param-myvalue'.  A good way to accomplish 
this is using make_query from ZTUtils in a python script which generates the 
PDF url for you like this:

from ZTUtils import make_query

form = getattr(request,'form',{})
query=''
if form: query='?'+make_query(form)

pdfurl=request.URL0+'/html2pdf'+query

return pdfurl


Hope that helps,
