cookies: reject oversized cookies #1894
The travis failure is not because of the patch.
I will however make sure the code also refuses truncated content, and it we should check to see what the max cookie name size some popular browsers use so that we don't reject cookies that are generally accepted.
... instead of truncating them. There's no fixed limit for acceptable cookie names in RFC 6265, but the entire cookie is said to be less than 4096 bytes (section 6.1). This is also what browsers seem to implement. We now allow max 5000 bytes cookie header. Max 4095 bytes length per cookie name and value. Name + value together may not exceed 4096 bytes.
