/**
|
||||
* Calling the API via AJAX
|
||||
* ========================
|
||||
*
|
||||
* These function make it possible to query the geo-data corresponding to the current visitor via AJAX.
|
||||
* This can be useful for Site Cache: If the variable content/behavior is injected via JS only, the HTML still can be cached.
|
||||
*
|
||||
* WARNING: We cannot completely prevent others from using this functionality, though, as JS requests can be faked.
|
||||
* To make this harder, we check the referer (so simply embeding the JS in another site won't work).
