# around cookie size limitations for most web browsers (usually 4096 bytes), the "client-cookie" will be split
# over a number of "chunked" cookies if the resulting session data is over a certain number of bytes, 
# If you want to prevent splitting the session cookie regardless of its size, set the value to 0.

# "pass" means that an unauthenticated request will pass but claims will still be passed when a user happens to be authenticated already
#
# Useful in Location/Directory/Proxy path contexts that serve AJAX/Javascript calls and for "anonymous access"
#
# When not defined the default is "auth" with auto-detection of requests that woult not be able to complete
# an authentication round trip to the OpenID Connect Provider, which would receive a 401.
# The default auto-detection algorithm looks for the "X-Requested-With: XMLHttpRequest" header/value, or

# a Sec-Fetch-Dest header with a value that is not equal to "document" or the absence of
# an "Accept" header with any of the values "text/html" "application/xhtml+xml" or "*/*"
# and returns 401 for such non-auth-capable requests, e.g. XML HTTP Requests, image loading requests etc.
# that would create a state cookie but never return to delete it.
# See: https://github.com/zmartzone/mod_auth_openidc/wiki/Cookies#tldr
# 
# Only for Apache >= 2.4.x:
# Since verson 2.4.4 a boolean Apache expression as the second parameter to specify which requests
# need to match to return the configured value in the first parameter to override the default "auth".
# See also: https://httpd.apache.org/docs/2.4/expr.html.
# E.g to only return 401 for cURL based user agents and "auth" for any other browsers/user agents:
#   OIDCUnAuthAction 401 "%{HTTP_USER_AGENT} =~ /curl/"
# to effectively override the default XML request detection algorithm by ignoring the Sec-Fetch-Mode,
# Sec-Fetch-Dest and Accept headers:
#   OIDCUnAuthAction 401 "%{HTTP:X-Requested-With} == 'XMLHttpRequest'"
# to return 401 for all user agents that do not send an Accept header that includes a "text/html" value:
#   OIDCUnAuthAction 401 "%{HTTP_ACCEPT} !~ m#text/html#"
# or as a more complex example, which equals the default XML request detection algorithm:
#   OIDCUnAuthAction 401 "%{HTTP:X-Requested-With} == 'XMLHttpRequest' \
#                     || ( -n %{HTTP:Sec-Fetch-Mode} && %{HTTP:Sec-Fetch-Mode} != 'navigate' ) \
#                     || ( -n %{HTTP:Sec-Fetch-Dest} && %{HTTP:Sec-Fetch-Dest} != 'document' ) \
#                     || (    ( %{HTTP_ACCEPT} !~ m#text/html# ) \
#                          && ( %{HTTP_ACCEPT} !~ m#application/xhtml\+xml# ) \
#                          && ( %{HTTP_ACCEPT} !~ m#\*/\*# ) )"
# To enable authentication in an iframe you need to change the Sec-Fetch-Dest part above in:
#                     || ( -n %{HTTP:Sec-Fetch-Dest} && %{HTTP:Sec-Fetch-Dest} != 'iframe' && %{HTTP:Sec-Fetch-Dest} != 'document') \
# For backwards compatibility with version < 2.4.10 you can remove the Sec-Fetch-Mode and Sec-Fetch-Dest parts.
# To disable auto-detection of XML HTTP request altogether and uncondtionally return "auth" for all clients:
#   OIDCUnAuthAction auth true
# Note that actually *any* expression value in "OIDCUnAuthAction auth <expr>" will *always* render "auth"
# (even when set to "false"...) because of the default, so using an <expr> value (other than "true") only
# makes sense in combination with one of the values other than "auth".

# Specify claims that should be removed from the userinfo and/or id_token before storing them in the session.
# Note that OIDCBlackListedClaims takes precedence over OIDCWhiteListedClaims
# When not defined no claims are blacklisted and all claims are stored except when OIDCWhiteListedClaims is used.

# Specify the minimum time-to-live for the access token stored in the OIDC session.
# When the access token expiry timestamp (or at tleast the hint given to that) is less than this value,
# an attempt will be made to refresh the access token using the refresh token grant type with the OP.
# This only has effect if a refresh token was actually returned from the OP and an "expires_in" hint
# was returned as part of the authorization response (and subsequent refresh token responses).
# When not defined no attempt is made to refresh the access token (unless implicitly with OIDCUserInfoRefreshInterval)
# The optional logout_on_error flag makes the refresh logout the current local session if the refresh fails.

# Define one or more regular expressions that specify URLs (or domains) allowed for post logout and
# other redirects such as the "return_to" value on refresh token requests, the "login_uri" value
# on session management based logins through the OP iframe, and the "target_link_uri" parameter in
# 3rd-party initiated logins, e.g.:
#   OIDCRedirectURLsAllowed ^https://www\.example\.com ^https://(\w+)\.example\.org ^https://example\.net/app
# or:
#   OIDCRedirectURLsAllowed ^https://www\.example\.com/logout$ ^https://www\.example\.com/app/return_to$
# When not defined, the default is to match the hostname in the URL redirected to against

# Defines the value of the X-Frame-Options header returned on OIDC front-channel logout requests.
# See also https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/X-Frame-Options.
# For example: 
#   OIDCLogoutXFrameOptions: sameorigin

# When not defined the default is "DENY".

# Define the X-Forwarded-* or Forwarded headers that will be taken into account as set by a reverse proxy

#  X-Forwarded-Proto
