httpcontext instances controllers zero asp.net mvc

this competence repremand proceed controllers, nonetheless i notice problem hadn't figured out proceed repremand it.

public jsonresult somecontrolleraction() {

    //the tide slight httpcontext only fine
    bool currentisnotnull = (this.httpcontext == null); //which fake    

    //creating new instance another controller
    someothercontroller controller = new someothercontroller();
    bool isnull = (controller.httpcontext == null); // true

    //the tangible httpcontext glorious both
    bool notnull = (system.web.httpcontext.current == null); // fake        

}

i've beheld httpcontext controller isn't "actual" httpcontext system.web.httpcontext.current.
