# Redmine stores query data in a session cookie in order to persist
# the last user query. This is havily used for issue queries.
# All the information configured for an issue query are appended to the url.
# The appendix is called query string. If this query string is to large for
# current the session cookie rails will raise an
# ActionDispatch::Cookies::CookieOverflow exception. Therefore, the byte
# size of a query string is limited to 30% of the maximum byte size of 4kb
# for a cookie.
# That is, query strings greater than the threshold won't be stored in order
# to avoid the exception.
# You can configure this value for your needs.
