I'm working on a script that, in order to reduce server load, should synchronize between multiple instances that can appear in multiple pages.
The idea is to have: User opens tabs A,B,C,D. Each one has an instance of the script. The user start the processing in the tabs A, B, C, D (just assume about 1s delay between each other and that they are in that order). The whole process to assist the user in gathering some data from the server and from connections related to the server. Multiple requests are required for each thing and that takes some time. In order to save on server load, my idea is to have B waiting for A to finish, C waiting for B to finish and D waiting for C to finish. It is also part of the idea to not rely on the server for this synchronization work as it would use load to do some work that should be possible to do without the server's intervention. My current problem is to synchronize all these so that D goes after C that goes after B that goes after A. While not forgetting that if the tab B is closed after A is complete, C should start (do not make infinite waits for B to complete). Also, if B is closed while working, C starts working and D continues to wait. I've been trying this with localstorage and the "storage" event and timeouts (with also heartbeats) but I'm having issues with infinite loops and with scripts running in the background. Any ideas? Even if not true, please assume that there is no alternative to doing the said requests to the server. -- You received this message because you are subscribed to the Google Groups "greasemonkey-users" group.
