The Web resource collection includes the following elements: URL patterns HTTP methods Answer: B.
Web resource collection is a set of URL patterns and HTTP operations that define all resources required to be protected.
It is a security constraint.
The Web resource collection is a security constraint element in the Java Servlet Specification v2.4, which is used to define a set of resources on a web application that are protected by security constraints. These security constraints can be used to restrict access to certain resources based on various factors such as authentication, authorization, and transport guarantees.
The Web resource collection element includes the following elements:
URL patterns: A URL pattern is a string that specifies a pattern of URLs that the security constraint applies to. It can contain wildcards and can be used to match a set of URLs that have a common structure. For example, the pattern "/admin/*" matches all URLs that start with "/admin/".
HTTP methods: HTTP methods specify the type of request being made to the web server. The security constraint can be applied to one or more HTTP methods such as GET, POST, PUT, DELETE, etc. For example, a security constraint can be applied to only the POST method to restrict access to a form submission.
Role names: Role names are used to specify which users or groups are allowed access to the resources protected by the security constraint. Role names are typically defined in the web application deployment descriptor and mapped to actual users or groups in the web container's security configuration.
Transport guarantees: Transport guarantees specify whether the resource must be accessed over a secure channel such as HTTPS. A transport guarantee can be set to either "CONFIDENTIAL" or "NONE". If the transport guarantee is set to "CONFIDENTIAL", the resource can only be accessed over a secure channel.
Therefore, the two elements that are included in the Web resource collection are URL patterns and HTTP methods. Role names and transport guarantees are also important elements in security constraints, but they are not specifically part of the Web resource collection element.
