Most webs use safe url base64 encode/decode to escape the special characters.
base64 encode/decode is similar to base64 safe url encode/decode.
The difference is the alphabet.
The base64 safe url alphabet uses '-' instead of '+' and '_'
instead of '/'.
after this patch:
In backend, we can encode an url:
>>
base64.urlsafe_b64encode("/vnc_auto.html?port=64667&path=?token=opensuse12&encrypt=1")
'L3ZuY19hdXRvLmh0bWw_cG9ydD02NDY2NyZwYXRoPT90b2tlbj1vcGVuc3VzZTEyJmVuY3J5cHQ9MQ=='
and in UI, we can decode it:
kimchi.urlSafeB64Decode("L3ZuY19hdXRvLmh0bWw_cG9ydD02NDY2NyZwYXRoPT90b2tlbj1vcGVuc3VzZTEyJmVuY3J5cHQ9MQ==")
"/vnc_auto.html?port=64667&path=?token=opensuse12&encrypt=1"

Safe url base64 is a variant of base64.

Most webs use safe url base64 encode/decode to escape the special
characters.
For special characters, there are functions called
encodeURIComponent()/decodeURIComponent() which are designed to do this.
(See: http://www.w3schools.com/jsref/jsref_encodeURIComponent.asp ,
http://www.w3schools.com/jsref/jsref_decodeuricomponent.asp)
For binary data (e.g. images), especially transferred between back-end
and front-end through AJAX, Base64 is the choice.
base64 encode/decode is similar to base64 safe url encode/decode.
The difference is the alphabet.
The base64 safe url alphabet uses '-' instead of '+' and '_'
instead of '/'.
