now not able how send information in http header method. appreciated.

you can use weboperationcontext.

system.servicemodel.web.weboperationcontext.current.outgoingresponse.headers.add("cache-control", "no-cache"); 

edit

i have used cache-control example here can specify valid http header. second parameter value wish set.
