Cross-domain communications with a shared worker application

A method comprising:ncreating, by a parent web application associated with a first domain, a child web application;associating the child web application with a second domain different than the first domain;determining, by the child web application, whether a shared worker application associated with the second domain is operating on a local computing device, wherein the shared worker application acquires information associated with the second domain in response to one or more requests, and stores acquired information associated with the second domain in a memory of the local computing device;if the child web application determines that the shared worker application associated with the second domain is operating on the local computing device, requesting, by the parent web application associated with the first domain, information associated with the second domain from the shared worker application via the child web application; andresponsive to requesting, receiving, by the parent web application associated with the first domain, the requested information associated with the second domain stored in the memory of the local computing device from the shared worker application via the child web application.

A computer-readable storage medium comprising instruction to cause a computing device to:ncreate, by a parent web application associated with a first domain, a child web application;associate the child web application with a second domain different than the first domain;determine, by the child web application, whether a shared worker application associated with the second domain is operating on a local computing device, wherein the shared worker application acquires information associated with the second domain in response to one or more requests, and stores acquired information associated with the second domain in a memory of the local computing device;if the child web application determines that the shared worker application associated with the second domain is operating on the local computing device, request, by the parent web application associated with the first domain, via the child web application, information associated with the second domain from the shared worker application; andreceive, by the parent web application associated with the first domain, from the shared worker application, information associated with the second domain stored in the memory of the local computing device in response to the requesting.

A computer system, comprising:na processor configured to execute computer program instructions;a parent web application associated with a first domain and executable by the processor to create a child web application that is associated with a second domain different than the first domain;the child web application operable to determine whether a shared worker application associated with the second domain is currently being executed by the processor, wherein the shared worker application acquires information associated with the second domain in response to one or more requests, and stores acquired information associated with the second domain in the memory,wherein the child web application receives a request from the parent web application for information associated with the second domain, and in response to the request, provides the requested information stored in the memory to the parent web application.
