 Requests' simple API means that all forms of HTTP request are as obvious. For
 example, this is how you make an HTTP POST request::
 
-    >>> r = requests.post('http://httpbin.org/post', data = {'key':'value'})
+    >>> r = requests.post('https://httpbin.org/post', data = {'key':'value'})
 
 Nice, right? What about the other HTTP request types: PUT, DELETE, HEAD and
 OPTIONS? These are all just as simple::
 
-    >>> r = requests.put('http://httpbin.org/put', data = {'key':'value'})
-    >>> r = requests.delete('http://httpbin.org/delete')
-    >>> r = requests.head('http://httpbin.org/get')
