+
+A domain transfered to the server can have one of the following types:
+
+* 1: the domain was entered without any further action
+* 2: the domain was recognized as a typo
+* 3: the domain is a correction that the user accepted
+* 4: the domain is a correction that the user declined
+
+The server expects the list to be transfered as a JSON object in no particular order. Here is an example:
+
+```js
+{
+  "urlfixer.org": 1,
+  "adblockplus,org": 2,
+  "adblockplus.org": 3,
+  "goggle.com": 1,
+  "google.com": 4
+}
+```
