Self.request.cookies.get is not returning complete value of the cookie in google app engine

I am setting the cookie value to (id, hash_of_id), but when the code is reading the value of the cookie it is getting only the part before comma. Not sure why:

These are the codes:

This is setting the values of the cookie named user_id.

self.response.headers.add_header('Set-Cookie', 'user_id = %s; Path=/' % id_hash)

The value of id_hash is coming from following:

def make_hash(user_id): return hmac.new(SECRET, str(user_id)).hexdigest()

def new_hash(user_id): id_hash = make_hash(user_id) return "%s,%s" %((user_id), id_hash)

id_hash = new_hash(user.key().id())

When I am checking the value of the cookie in the browser using Edit this Cookie extension, it shows something like this:

This shows cookie has got id and hashed value of id.

Now value of cookie is being read:

cookiess = self.request.cookies.get('user_id')

When I am displaying the value of variable cookiess using

self.render("welcome.html", username = cookiess)

It shows only the part before comma,

enter image description here

I am not able to understand why the self.request.cookie.get returns value only till comma and not complete value.

Came to know that there is a bug in google appengine due to which

self.request.cookie.get()

was returning value only till comma. Instead of comma if something else like a pipe (|) is used as separator, then this function is working properly.
