Question

I am starting a long polling request for every page of my website. It looks every second at the database and if there is something new it marks it as seen and outputs the notification. The calling JavaScript is then starting a new ajax request.

Now I got problems having opened multiple tabs on the website, because only one will recieve a new notification. This is also a problem cross-browser with the same username logged in…

What would be the smartest way to solve this fool-proof?

Than you for your input!

Answer 1

I think it is better to avoid browser pulling. You will have browsers problems and also your infrastructure should be huge to support it.

Try a server side pushing tech like Commet,

Comet is a web application model in which a long-held HTTP request
allows a web server to push data to a browser, without the browser
explicitly requesting it.

Other approach could be using WebSockets.
