/**
* Returns the value of the named attribute as an Object, or
* null if no attribute of the given name exists.
*
* Attributes can be set two ways. The servlet container may set attributes
* to make available custom information about a request. For example, for
* requests made using HTTPS, the attribute
* javax.servlet.request.X509Certificate can be used to
* retrieve information on the certificate of the client. Attributes can
* also be set programmatically using {@link ServletRequest#setAttribute}.
* This allows information to be embedded into a request before a
* {@link RequestDispatcher} call.
*
* Attribute names should follow the same conventions as package names.
* Names beginning with java.* and javax.* are
* reserved for use by the Servlet specification. Names beginning with
* sun.*, com.sun.*, oracle.* and
* com.oracle.*) are reserved for use by Oracle Corporation.
*
* @param name
* a String specifying the name of the attribute
* @return an Object containing the value of the attribute, or
* null if the attribute does not exist
