Cookie parse - failed

[gendalf]

After put node+connect in production 5% of request kill server... (multilanguage project)

CAUSE: Not always cookies is encoded with URIComponent, many requests have encoded cookies with escape
Patch lines in cookie/index.js

WAS:
obj[key] = decode(val)

My code for production:
try {
obj[key] = decode(val);
} catch(err) {
try {
obj[key] = unescape(val);
} catch(err){
console.log('FAIL DECODE COOKIE:', val);
}
}

Can you provide an example of a valid cookie which is not a valid URI or cannot be decoded?
