Hi David
In the PHP example that you gave, try changing it to:
$query = json_encode(array('key~'=>'/about/*'));
The slashes in that string gets escaped by the JSON ecoder. If you already escape them before encoding, it gets double-escaped to look like this:
{"key~":"\\\/about\\\/*"}
That is probably why you got an error message from the API.
I don't think that this is an issue in almost all programming languages. The point is that you don't want to name any variables 'key~' but this is just a string key in an associative array (or HashMap or dict whatever your programming language calls it).
