Says: " The user's IP address is available in the standard X-Forwarded-For header "
However this is not the case, doing some debugging the HTTP request headers I always see are:
"x-real-ip": "169.254.160.2",
"x-forwarded-for": "169.254.160.2",
"x-google-real-ip": "169.254.160.2",
These are link local IP addresses and can not be correct.
Documentation bug or app engine bug?
