Usage: `/cookie.py?set={cookie}`

The passed-in cookie string should be stringified via JSON.stringify() (in
|
|
the case of multiple cookie headers sent in an array) and encoded via
|
|
encodeURIComponent, otherwise `parse_qsl` will split on any semicolons
|
|
(used by the Request.GET property getter). Note that values returned by
|
|
Request.GET will decode any percent-encoded sequences sent in a GET param
|
|
(which may or may not be surprising depending on what you're doing).
|
|
|
|
Note: here we don't use Response.delete_cookie() or similar other methods
|
|
in this resources directory because there are edge cases that are impossible
|
|
to express via those APIs, namely a bare (`Path`) or empty Path (`Path=`)
|
|
attribute. Instead, we pipe through the entire cookie and append `max-age=0`
|

to it.
