+As an alternative if you're using VCR, you can ignore requests coming from the browser.
+One way of doing that is by adding to your `rails_helper.rb` the excerpt below:
+
+```ruby
+VCR.configure do |config|
+  config.ignore_request do |request|
+    request.headers.include?('Referer')
+  end
+end
+```
+
+Note that this approach may cause unexpected behavior if your backend sends the Referer HTTP header (which is unlikely).
