 {{request.http referer}} ??

 <input type="button" value="Back" /> //onlcick how to call the referrer 

Answer 1

That piece of information is in the META attribute of the HttpRequest, and it's the HTTP_REFERER (sic) key, so I believe you should be able to access it in the template as:

{{ request.META.HTTP_REFERER }}

Works in the shell:

>>> from django.template import *
>>> t = Template("{{ request.META.HTTP_REFERER }}")
>>> from django.http import HttpRequest
>>> req = HttpRequest()
>>> req.META
{}
>>> req.META['HTTP_REFERER'] = 'google.com'
>>> c = Context({'request': req})
>>> t.render(c)
u'google.com'

Answer 2

Rajeev, this is what I do:

 <a href="{{ request.META.HTTP_REFERER }}">Referring Page</a>
