2.4 Using URL Parameters
URL
parameters are strings that are sent to the server with the client
request. The parameters are inserted into the
HttpServletRequest
object from the URI query string and
data that is sent in a POST method. The parameters are formatted as
key/value pairs and are accessed by applications as request
parameters. URL parameters play an important role in all web
applications, and the Struts framework is no exception. |
Don't get request parameters confused with request
attributes. Attributes are objects that typically are inserted into
the request so that they can be made available to other servlets,
such as JSP pages. |
