I have the following code:
var previousPageUrl= document.referrer;
alert(previousPageUrl);
This will not work if the previous page url is of any external site, i.e., not of my application.
For example:
If I am in Page 1 and went to Page 2 of my application then I will get page 1 url in referrer in Page 2 load but when I go to external site say then again when I come back to page 1 the I will not get as referrer url.
Can Somebody tell to resove this issue.

Generally, Referer URLs are passed between unrelated sites when navigation occurs due to a link click or JavaScript-based navigation. Referer URLs are NOT sent if the user uses the browser's chrome (e.g. address bar, back/forward buttons/etc) to navigate.
For security/privacy reasons, the Referer URL is stripped out when navigating from a HTTPS site to a HTTP site (e.g. from to ). It can also be deliberately stripped out via a variety of JavaScript and HTML tricks. There is no way to disable this behavior to get the Referer URL if it has been stripped.
