title: Spring-Security: Difference Between /** and /* url pattern in Spring-Security
body: <p>I am little bit confuse with URL-pattern in spring security. Because, in servlet core http security, the <code>/</code> and <code>/*</code> url patterns are used for specify one or more directories. <code>/</code> is use for one directory and <code>/*</code> is used of many directories. But in spring-security, the <code>/**</code> is also introduce, what is the main purpose of <code>/**</code> url-pattern in security. </p>
