You can also see preNavigationHooks [1] & postNavigationHooks [2] e.g.

    preNavigationHooks: [

        const cookie = context.request.headers['cookie'];
        context.log.info(`pre-nav: cookie is '${cookie}'`);
      }],
    postNavigationHooks: [
      async (context) => {
        const url = context.request.url;
        const cookie = context.request.headers['cookie'];
        context.log.info(`post-nav: cookie is '${cookie}'`);
      }],

    preNavigationHooks: [
      async (context) => {
        const url = context.request.url;
        const cookie = context.request.headers['cookie'];
        context.log.info(`pre-nav: cookie is '${cookie}'`);
      }],
    postNavigationHooks: [
      async (context) => {
        const url = context.request.url;
        const cookie = context.request.headers['cookie'];
        context.log.info(`post-nav: cookie is '${cookie}'`);
      }],
