# This can be inserted in a before filter, or an endpoint causing cookie overflows |
|
# this will log data for users who are approaching the max_cookie_size |
|
# it will also for the most common cookie to overflow session, break down the size by key value pairs. |
|
# This logs cookie and key names, but none of the data which may include PII, it just logs the byte sizes |
|
# |
|
# How to read: |
|
# Cookie Debug (size: 3280) # overall cookies total size in bytes |
|
# [COOKIE_NAME] size=IN_BYTES # these are sorted by smallest to largest byte size |
|
# session: [KEY] size=IN_BYTES # for the session cookie, the key name with values in byte size sorted |
|
# |
|
# example output: |
|
