In my website, i want to check that whether the user has opened the homepage of my website in same tab again or in the new tab? Is there any solution to check that?

  • What do you mean "in the same tab again?" Are you trying to check whether he loaded the page fresh, or if he just reloaded the page? That is possible... – JasCav Oct 15 '13 at 13:57
  • @JasCav, How do we differentiate load fresh && reload in server side? Other than having a hidden field in the page value set to `loaded` and checking it in Request collection? :) – Murali Murugesan Oct 15 '13 at 14:03
  • Browsers don't maintain a constant connection to web servers, so it's not possible to *reliably* determine if a user has a web page open in more than one window. – Blazemonger Oct 15 '13 at 14:03

The closest you can get is by checking to see if your current tab or window has any history...

if (history.length > 1) {
    // you're in an old tab
} else {
    // you're in a new tab
}

This is in Javascript, not server-side, but I don't see how you'd be able to detect anything like this in server-side code.

  • I haven't used Firefox in a while, but it failed to preserve the history when opening a link on a new tab (Ctrl / Scroll-click). – CodeCaster Oct 15 '13 at 14:40
  • @CodeCaster That's the whole point. A new tab would only have 1 entry in the history. Or am I misunderstanding your comment? – Reinstate Monica Cellio Oct 15 '13 at 14:41
  • Well Chrome for example _does_ copy the history of the tab you're coming from, but also not in all cases: Ctrl/Scroll-click a link and the history is cleared, but Ctrl/Scroll-click the Back button and your history get copied. – CodeCaster Oct 15 '13 at 14:42
  • @CodeCaster No it doesn't. If you're opening a link in a new tab then there is no history. Try it on this page, using Chrome. I just did :) – Reinstate Monica Cellio Oct 15 '13 at 14:43
  • but if the user is already using the tab for another websites, then that will have the history. then what to do? – Nav Purewal Oct 15 '13 at 14:54
  • This will tell you if the user has gone to the home page in an existing tab, or a new tab. – Reinstate Monica Cellio Oct 15 '13 at 14:55
