Method and apparatus for implementing co-browsing between domains

摘要

A communication session extant via a first browser window may be continued from a first web page in a first domain to a second web page in a second domain by causing the second web page to be opened in a second browser window. The first browser window and second browser window open message handlers and use post message to forward a communication session ID to the second browser window. Where the communication session ID is written into a first domain first-party cookie by script on the first web page, messaging the communication session ID to the second browser window enables script on the second web page to write the value of the first domain first-party cookie into a second domain first-party cookie. The communication session ID can then be used to continue the communication session by the script of the second web page.
