title: Django URL without trailing slash not working
body: <p><a href="https://i.stack.imgur.com/luW58.png" rel="noreferrer"><img src="https://i.stack.imgur.com/luW58.png" alt="Updated Page not found (404)"></a></p>
  
  <p>This is a silly problem. I just created a project and have been trying to figure out this problem.</p>
  
  <pre><code>from django.conf.urls import url
  from django.views.generic import TemplateView
  
  urlpatterns = [
      url(r'^$', TemplateView.as_view(template_name="index.html")),
      url(r'^about$', TemplateView.as_view(template_name="about.html")),
      url(r'^contact$', TemplateView.as_view(template_name="contact.html"), name="contact"),
      url(r'^test$', TemplateView.as_view(template_name="test_start"), name="test_start"),
      url(r'^test/sample$', TemplateView.as_view(template_name="test_start"), name="test_start"),
  ]
  </code></pre>
  
  <p>is included into</p>
  
  <pre><code>from django.conf.urls import url, include
  from django.contrib import admin
  
  urlpatterns = [
      url(r'^admin/', admin.site.urls),
      url(r'^', include('frontend.urls'))
  ]
  </code></pre>
  
  <p>When I go to <code>localhost:8000/about</code>, I get redirected to <code>localhost:8000/about/</code> and there I get 404 Not Found.</p>
  
  <p>UPDATE: I added more URLs into my URLconf.</p>
  
  <p>UPDATE 2: I meant to not include trailing slashes. My apologies.</p>
  
  <p>UPDATE 3: I opened the same URL in Firefox and the URL works like I intend. Could this be a problem with redirection and browser cache?</p>
