+Helper function that creates outbound HTTP connection.
+
+`url` is a URL to fetch. It must be properly URL-encoded, e.g. have
+no spaces, etc. By default, `mg_connect_http()` sends Connection and
+Host headers. `extra_headers` is an extra HTTP headers to send, e.g.
+`"User-Agent: my-app\r\n"`.
+If `post_data` is NULL, then GET request is created. Otherwise, POST request
+is created with the specified POST data. Note that if the data being posted
+is a form submission, the `Content-Type` header should be set accordingly
+(see example below).
+
+Examples:
+
+```c
+  nc1 = mg_connect_http(mgr, ev_handler_1, "http://www.google.com", NULL,
+                        NULL);
+  nc2 = mg_connect_http(mgr, ev_handler_1, "https://github.com", NULL, NULL);
+  nc3 = mg_connect_http(
+      mgr, ev_handler_1, "my_server:8000/form_submit/",
+      "Content-Type: application/x-www-form-urlencoded\r\n",
+      "var_1=value_1&var_2=value_2");
+```
