Can I programmatically tell when a new tab is opened in the browser?

I'm addressing a problem with an ASP .NET web application where I want to avoid using query strings to uniquely identify dynamic content. I want to index the content relative t开发者_C百科o the opened tab/window that is displaying it. Is this programmatically possible? If so, what is the compatibility of the approach across multiple browsers? Thank you for your help.

No. It's not really any different to the user opening a new browser window, or opening the calculator application to work something out, etc. It happens outside the context of your web page and, short of a browser plugin, you can't get notification of this.

No, it's not possible by "tab" (i.e., browser window instance).

The closest you'll get is to drive new page requests off of session data established in previous requests but that's really a far cry from what you're asking asking for.

I'd tell whomever is "tasking" you with this that they are a moron you can't change the fundamental communication protocols of the web.
