When a visitor uses the Back button on the browser to step backwards through the session pages, these pages are retrieved from the browser's local cache, and the browser does not send any requests to the web server for this information.

Because cxImpact captures interactions between a browser and a web server, a visitor's use of the Back button is not captured. However, Experience Analytics can track the event by monitoring the page referrer (HTTP_REFERER) field in the subsequent request to identify clicks of the Back button. If the value of the HTTP_REFERER field references an earlier page in the User Impression stack, RTV indicates that the Back button was pressed.

In Replay View, the Viewable Pages list shows a green box that contains a left-facing arrow, and in the main window the word back is placed in the upper-right corner of the Content pane.

In the Viewable Pages list, a dummy page representing Back button sequencing is inserted. For example, the pattern 10*(8) indicates that page 8 was seen after page 10, and the user impression was the same as page 8. The number in parentheses is the nearest previous page number whose URL matches the value of the HTTP_REFERER.

Because Back button detection is an interpolation of known hits, it may not be accurate and may not work on all sites. Depending on your site's architecture, you may want to disable Back Button Detection through the Replay options.
