Cookie encoding inconsistency

[kirpit]

Django is encoding cookie values and if, only if any of its value is encoded, wrapping the entire value within double quotes.

django/http/__init__.py starts from the line #84 (for 1.4.3):

# If encoded now contains any quoted chars, we need double quotes
# around the whole string.
if "\\" in encoded and not encoded.startswith('"'):
  encoded = '"' + encoded + '"'

That means, the value hello will be stored as hello but hello world will be stored as "hello world".

I believe this is totally inconsistent and difficult to handle from client side. For example, you simply cannot use ​jquery.cookie to get the exact value without writing some double quotes checking javascript code.

If you use jquery.cookie with its default values ($.cookie.raw = false; and $.cookie.json = false;) you get the server-side set value with double quotes around it (as in var value = '"hello world"';)

If you use it with $.cookie.json = true;, you get the double quoted values fine (as in var value = "hello world";) but you get syntax error (for hello) because it is trying JSON.parse('hello'), which is not a valid JSON string.

Actually, This seems to be a problem of that jquery.cookie library you are using: ​https://github.com/carhartl/jquery-cookie/pull/57
