The name of the permission is the url string. + * The actions string is a concatenation of the request methods and headers. + * The range of method and header names is not restricted by this class. + *

The url

+ * The url string is also used to instantiate a {@link URI} object which is + * used for comparison with other HttpURLPermission instances. Therefore, any + * references in this specification to url, mean this URI object. + * The path component of the url comprises a sequence of path segments, separated + * by '/' characters. The path is specified in a similar way to the path + * in {@link java.io.FilePermission}. There are three different ways + * as the following examples show: + * + * + * + * + * + * + * + * + * + * + *
Example urlDescription
http://www.oracle.com/a/b/c.htmlA url which identifies a specific (single) resource
http://www.oracle.com/a/b/*The '*' character refers to all resources in the same "directory" - in + * other words all resources with the same number of path components, and + * which only differ in the final path component, represented by the '*'. + *
http://www.oracle.com/a/b/- + * The '-' character refers to all resources recursively below the + * preceding path (eg. http://www.oracle.com/a/b/c/d/e.html matches this + * example). + *
+ *

+ * The '*' and '-' may only be specified in the final segment of a path and must be + * the only character in that segment. Any query or fragment components of the + * url are ignored when constructing HttpURLPermissions. + *

+ * As a special case, urls of the form, "http:*" or "https:*" are accepted to + * mean any url of the given scheme. + *

The actions string

+ * The actions string of a HttpURLPermission is a concatenation of the method list + * and the request headers list. These are lists of the permitted HTTP request + * methods and permitted request headers of the permission (respectively). The two lists + * are separated by a colon ':' character and elements of each list are comma separated. + * Some examples are: + * 

+ *         "POST,GET,DELETE"
+ *         "GET:X-Foo-Request,X-Bar-Request"
+ *         "POST,GET:Header1,Header2"
+ *
+ * The first example specifies the methods: POST, GET and DELETE, but no request headers. + * The second example specifies one request method and two headers. The third + * example specifies two request methods, and two headers. + *

+ * The colon separator need not be present if the request headers list is empty. + * No white-space is permitted in the actions string. The action strings supplied to + * the HttpURLPermission constructors are case-insensitive and are normalized by converting + * method names to upper-case and header names to the form defines in RFC2616 (lower case + * with initial letter of each word capitalized). Either list can contain a wild-card '*' + * character which signifies all request methods or headers respectively. + *

+ * Note. Depending on the context of use, some request methods and headers may be permitted + * at all times, and others may not be permitted at any time. For example, the + * HTTP protocol handler might disallow certain headers such as Content-Length + * from being set by application code, regardless of whether the security policy + * in force, permits it. + * + * @since 1.8 + */ +public final class HttpURLPermission extends Permission { + + private static final long serialVersionUID = -2702463814894478682L; + + private transient URI uri; + private transient List methods; + private transient List requestHeaders; + + // serialized field + private String actions; + + /** + * Creates a new HttpURLPermission from a url string and which permits the given + * request methods and user-settable request headers. + * The name of the permission is its url string.
