rr module has check_route_param(re) function that can be used to check if local route header has a param that matches re. however, there does not exist a function to find out what is the value of a given rr param. for example, if route header has param ;param=foo, how to extract value foo of param? there is @rr.uri.params select that together with {param.value,name} transformation might be able to do the job? -- juha
