Notes for Custom 401 Pages

• Do not set the Custom401errorfile parameter to a URL.
• If a value (usable or not) for Custom401errorfile exists, the Agent will check every 60 seconds to see if the file has changed. However, the response is intended to be static in nature. You cannot, for example, insert a "user_name denied" type of dynamic message.

  Because re-checking is triggered by the existence of the Custom401errorfile value rather than its usability, you can correct an error without restarting the agent. The correction will be picked up on the next check.

• The customized message file text will not be exposed by other errors. The file pathname will be logged at startup and in the case of error.
• The extent of customization may be limited by the web server, which may add text of its own to the response.
• The size of the customized text file is limited only by the system file size limit.
