Rails log cookie information if ActionDispatch::Cookies::CookieOverflow error

Question

I am raising a ActionDispatch::Cookies::CookieOverflow error.

In theory I know why this is happening, my session data is over 4k.

However I dont know what in my session would make it over 4k.

The stack trace of the error is as follows:

raise CookieOverflow if options[:value].size > MAX_COOKIE_SIZE

Is it possible to override ActionPack and log options[:value]

Also it is not an option to store sessions in the database as the database would grow too fast.

Thanks

Answer 1

I ended up forking ActionPack and monkey patching it to raise and error with the cookie
