I\'ve got two applications located on two separate computers. On computer A, in the urls.py file I have a line like the following:

(r\'^cast/$\         


        

Answer 1

Append slash without redirect, use it instead of CommonMiddleware in settings, Django 2.1:

MIDDLEWARE = [
    ...
    # 'django.middleware.common.CommonMiddleware',
    'htx.middleware.CommonMiddlewareAppendSlashWithoutRedirect',
    ...
]

Add to your main app directory middleware.py:

from django.http import HttpResponsePermanentRedirect, HttpRequest
from django.core.handlers.base import BaseHandler
from django.middleware.common import CommonMiddleware
from django.conf import settings


class HttpSmartRedirectResponse(HttpResponsePermanentRedirect):
    pass


class CommonMiddlewareAppendSlashWithoutRedirect(CommonMiddleware):
    """ This class converts HttpSmartRedirectResponse to the common response
        of Django view, without redirect.
    """
    response_redirect_class = HttpSmartRedirectResponse

    def __init__(self, *args, **kwargs):
        # create django request resolver
        self.handler = BaseHandler()

        # prevent recursive includes
        old = settings.MIDDLEWARE
        name = self.__module__ + '.' + self.__class__.__name__
        settings.MIDDLEWARE = [i for i in settings.MIDDLEWARE if i != name]

        self.handler.load_middleware()

        settings.MIDDLEWARE = old
        super(CommonMiddlewareAppendSlashWithoutRedirect, self).__init__(*args, **kwargs)

    def process_response(self, request, response):
        response = super(CommonMiddlewareAppendSlashWithoutRedirect, self).process_response(request, response)

        if isinstance(response, HttpSmartRedirectResponse):
            if not request.path.endswith('/'):
                request.path = request.path + '/'
            # we don't need query string in path_info because it's in request.GET already
            request.path_info = request.path
            response = self.handler.get_response(request)

        return response
