IG 2023.2


Calls the AM endpoint for session information, and makes the data available as a new context to downstream IG filters and handlers. For information, see SessionInfoContext.

WebSocket notifications for sessions

When WebSocket notifications are set up for sessions, IG receives a notification from AM when a user logs out of AM, or when the AM session is modified, closed, or times out. IG then evicts entries that are related to the event from the sessionCache.

For information about setting up WebSocket notifications, using them to clear the session cache, and including them in the server logs, refer to WebSocket notifications.


  "name": string,
  "type": "SessionInfoFilter",
  "config": {
    "amService": AmService reference,
    "ssoToken": runtime expression<string>


"amService": AmService reference, required

The AmService object to use for communication with AM.

The following sessionProperties, are retrieved from AM:

  • When sessionProperties in AmService is configured, listed session properties with a value.

  • When sessionProperties in AmService is not configured, all session properties with a value.

  • Properties with a value that are required by IG but not specified by sessionProperties in AmService. For example, when the session cache is enabled, session properties related to the cache are automatically retrieved.

Properties with a value are returned, properties with a null value are not returned.

"ssoToken": runtime expression<string>, optional

Location of the AM SSO or CDSSO token.

This property can take the following values:

  • ${contexts.ssoToken.value}, when the SingleSignOnFilter is used for authentication

  • ${contexts.ssoToken.value} or ${contexts.cdsso.token}, when the CrossDomainSingleSignOnFilter is used for authentication

  • ${request.headers['mySsoToken'][0]}, where the SSO or CDSSO token is the first value of the mySsoToken header in the request.

Default: ${request.cookies['AmService-ssoTokenHeader'][0].value}, where AmService-ssoTokenHeader is the name of the header or cookie where the AmService expects to find SSO or CDSSO tokens.


For an example that uses the SessionInfoFilter, see Retrieve a Username From the sessionInfo Context.
