django previous url

In Django, you can access the previous URL using the request.META.get('HTTP_REFERER') method. Here's an explanation of each step:

1. request: This is a parameter that represents the HTTP request made by the user.
2. META: This is a dictionary containing all available HTTP headers. It includes information about the user agent, referrer, and other metadata related to the request.
3. get('HTTP_REFERER'): This method retrieves the value of the 'HTTP_REFERER' key from the META dictionary. The 'HTTP_REFERER' key contains the URL of the previous page from where the user came from.

By using request.META.get('HTTP_REFERER'), you can obtain the URL of the previous page and use it for further processing or redirection within your Django application.
