Recently, I stumbled upon the platform Polyvore and decided to test it out.
While experimenting with its "Create a set" feature, I noticed that the site provides a view of items either from your own collection or sourced elsewhere. An interesting observation I made was that if I were to open two tabs in the same browser - one displaying the list of items and the other for adding a new item to my collection - the former would automatically update when changes are made on the latter. This synchronization between tabs only occurs when within the same browser window. Is this functionality related to something known as "push ajax"?
I'm curious to learn more about how to implement a similar feature. Can someone provide guidance on building such a capability?
