Include Tag:
bean:include Tag - is used to load the response from a dynamic application request and make it available as a bean.
This tag performs an internal dispatch to the specified application component (or external URL) and makes the response data available from that request as a bean of type String.
Include tag works similar to that of the standard <jsp:include> tag, except
that the response data is stored in a page scope attribute instead of being written to the output stream. If the current
request is part of a session, the generated request for the include be part of the same
session.

| href |
This attribute specifies the absolute URL (including the appropriate protocol prefix such as "http:") of the resource to be included. Because this URL could be external to the current web application, the session identifier will not be included in the request. |
