Redirect / return to same (previous) page in Django?

Question

What are the options when you want to return the user to the same page in Django and what are the pros/cons of each?

Methods I know:

• HTTP_REFERER
• GET parameter containing the previous URL
• Session data to store the previous URL

Are there any other?

Answer 1

One of the way is using HTTP_REFERER header like as below:

from django.http import HttpResponseRedirect

def someview(request):
   ...
   return HttpResponseRedirect(request.META.get('HTTP_REFERER'))

Not sure of cons of this!
