Banner Page and Inactivity Timeout for HTTP or HTTPS Connections

The Banner Page and Inactivity Timeout for HTTP or HTTPS Connections feature allows you to create a banner page and set an inactivity timeout for HTTP or HTTP Secure (HTTPS) connections. The banner page allows you to log in to the server when the session is invalid or expired.

Validation of an HTTP Session

When a user sends an HTTP request to an HTTP server, the request is processed as follows:

  1. The HTTP server parses the cookies and extracts the session information from them. Cookies are used to preserve the browser's across many pages and over periods of time. Every time a web browser accesses content from a domain or a URL, if a cookie exists, the browser submits the cookie information as part of the HTTP request.

  2. The server checks whether the session ID provided in the cookie is valid.
  3. If the session ID is valid, the server bypasses the authentication.

  4. If the session ID is invalid or has expired, the server sends a redirect response. A customizable banner page is sent to the user. The banner page allows the user to log in with credentials. The server then validates the credentials and processes the request.

    Use the command ip http banner to enable an HTTP or an HTTP Secure (HTTPS) banner and the command ip http banner-path path-name to direct the user to the banner page.

    If a session exceeds the default timeout of 3 minutes, the session ID is deleted from the HTTP server and the user is redirected to the banner page. To set the inactivity timeout for a session, use the command ip http session-idle-timeout.
