# Method name: referrer()

# Method package: wixWindowFrontend

# Method menu location: wixWindowFrontend --> referrer

# Method Link: https://dev.wix.com/docs/velo/apis/wix-window-frontend/referrer.md

# Method Description:

Gets the HTTP referrer header field.

The `referrer` is the address of the web page a site visitor was previously
 on before arriving at the current page, typically by clicking a link.

 > **Note:** When site visitors move from page to page in a site, the `referrer` property
 does not contain the address of the page the site visitor came from. This is because
 Wix sites are built as [single page applications](https://en.wikipedia.org/wiki/Single-page_application).
 To get the previous page a site visitor was visiting in a site, you can
 use the Storage APIs to store the visitor's current page
 and retrieve the visitor's previous page.



# Method Code Examples:

*** Note: do not assume any prop names or enum values other than the ones in the example.

## Get the referrer information

```javascript
import wixWindowFrontend from 'wix-window-frontend';

// ...

let referrer = wixWindowFrontend.referrer;  // "http://somesite.com"
```

## Get the previous page in a Wix site

```javascript
// In Site tab

import {session} from 'wix-storage-frontend';
import wixLocationFrontend from 'wix-location-frontend';

let previousPageURL;

$w.onReady(function () {
  previousPageURL = session.getItem("page");
  session.setItem("page", wixLocationFrontend.url);
});

```
