How do I redirect domain.com to WWW.domain.com under Django?
How do I go about redirecting all requests for domain.com/... to www.domain.com/... with a 301 in a django site?
Obviously this can't be done in urls.py because you only get the path part of the URL in there.
I can't use mod rewrite in .htaccess, b开发者_JS百科ecause .htaccess files do nothing under Django (I think).
I'm guessing something in middleware or apache conf?
I'm running Django on a Linux server with Plesk, using mod WSGI
The WebFaction discussion someone pointed out is correct as far as the configuration, you just have to apply it yourself rather than through a control panel.
RewriteEngine On
RewriteCond %{HTTP_HOST} ^example.com$
RewriteRule (.*) http://www.example.com/$1 [R=301,L]
Put in .htaccess file, or in main Apache configuration in appropriate context. If inside of a VirtualHost in main Apache configuration, your would have ServerName be www.example.com and ServerAlias be example.com to ensure that virtual host handled both requests.
If you don't have access to any Apache configuration, if need be, it can be done using a WSGI wrapper around the Django WSGI application entry point. Something like:
import django.core.handlers.wsgi
_application = django.core.handlers.wsgi.WSGIHandler()
def application(environ, start_response):
if environ['HTTP_HOST'] != 'www.example.com':
start_response('301 Redirect', [('Location', 'http://www.example.com/'),])
return []
return _application(environ, start_response)
Fixing this up to include the URL within the site and dealing with https is left as an exercise for the reader. :-)
The PREPEND_WWW setting does just that.
There is a lightweight way to do that involving VirtualHosts and mod_alias Redirect directive. You can define two VirtualHosts, one holding the redirect and another holding the site configuration:
<VirtualHost *:80>
ServerName example.com
Redirect permanent / http://www.example.com/
</VirtualHost>
<VirtualHost *:80>
ServerName www.example.com
# real site configuration
</VirtualHost>
And that will do the job.
This also can be done with a middleware.
Some examples:
- http://eikke.com/django-domain-redirect-middleware/
- https://djangosnippets.org/snippets/510/
- https://djangosnippets.org/snippets/434/
This is a better version of snippet-510:
class UrlRedirectMiddleware(object):
"""
This middleware lets you match a specific url and redirect the request to a
new url. You keep a tuple of (regex pattern, redirect) tuples on your site
settings, example:
URL_REDIRECTS = (
(r'(https?)://(www\.)?sample\.com/(.*)$', r'\1://example.com/\3'),
)
"""
def process_request(self, request):
full_url = request.build_absolute_uri()
for url_pattern, redirect in settings.URL_REDIRECTS:
match = re.match(url_pattern, full_url)
if match:
return HttpResponsePermanentRedirect(match.expand(redirect))
