Cookie headers in examples are incorrect

[ThisIsMissEm]

In examples 8, 12, 15 the cookie header is written as Cookie: 0x23223 when it should be something like either:

Cookie: name=value
Cookie: name=value; name2=value2; name3=value3

(taken from MDN)

We should probably correct that header value to something that's correct. Perhaps Cookie: exampleName=exampleValue; exampleName2=exampleValue2
