- Request Object
  The request object represents the HTTP request. It contains properties that provide details and context about the request, as well as properties that allow for modifying the request.
- User Location Object
  The userLocation request object contains properties specifying the geographic location.
- Device Object
  The device property specifies client device characteristics.
- CacheKey Object
  The cacheKey object contains methods to modify a cacheKey for an HTTP request.
- Response Object
  The response object represents the HTTP response and includes key:value pairs for the status and headers. Response headers can only be modified during the onClientResponse and onOriginResponse events.

    - HTTP sub-requests
      EdgeWorkers supports HTTP requests made from within an event handler. These HTTP sub-requests provide a logical way to fetch resources asynchronously across the network. If you want your callback to wait for the subrequest to complete, the event handlers should return a Promise or be declared async.
  - cookies
  - url-search-params
  - log
