Use this page to define the domain-wide Web application configuration settings.
Name Description Relogin Enabled
Beginning with the 9.0 release the FORM/BASIC authentication behavior has been modified to conform strictly to the J2EE Specification. If a user has logged-in but does not have privileges to access a resource, the 403 (FORBIDDEN) page will be returned. Turn this flag on to enable the old behavior, which was to return the user to the login form.
Allow All Roles
In the security-constraints elements defined in a Web application's web.xml deployment descriptor, the auth-constraint element indicates the user roles that should be permitted access to this resource collection. Here role-name = "*" is a compact syntax for indicating all roles in the Web application. In previous releases, role-name = "*" was treated as all users/roles defined in the realm. This parameter is a backward-compatibility switch to restore old behavior. Default behavior is one required by the spec, meaning all roles defined in the web application. If set, the value defined in weblogic.xml (container-descriptor -> allow-all-roles) takes precedence (if set) over this value.
Filter Dispatched Requests
Indicates whether or not to apply filters to dispatched requests. This is a backward compatibility flag. Until version 8.1, WebLogic Server applied ServletFilters (if configured for the Web application) on request dispatches (and includes/forwards). Servlet 2.4 has introduced the "Dispatcher" element to make this behavior explicit. The default value is Dispatcher=REQUEST. In order to be complaint with the J2EE specification, the default value for FilterDispatchedRequestsEnabled is false beginning with WebLogic Server 9.0. Note that if you are using old descriptors (meaning web.xml does not have version=2.4), then WebLogic Server automatically uses FilterDispatchedRequestsEnabled = true for the Web applications, unless filter-dispatched-requests-enabled is explicitly set to false in weblogic.xml. This means that old applications will work fine without any modification. Additionally, during migration of old domains to the 9.0 domain, the migration plugin automatically sets this flag to true.
Overload Protection Enabled
This parameter is used to enable overload protection in the webapp container against low memory conditions. When a low memory situation occurs, new session creation attempts will result in weblogic.servlet.SessionCreationException. The application code needs to catch this exception and take proper action. Alternatively appropriate error-pages can be configured in web.xml against weblogic.servlet.SessionCreationException. This check is performed only on memory and replicated sessions.
WebLogic Server uses the X-Powered-By HTTP header, as recommended by the Servlet 2.4 specification, to publish its implementation information.
Following are the options:
"NONE": X-Powered-By header will not be sent
"SHORT" (default): "Servlet/2.4 JSP/2.0"
"MEDIUM": "Servlet/2.4 JSP/2.0 (WebLogic/9.1)"
"FULL": "Servlet/2.4 JSP/1.2 (WebLogic/9.1 JDK/1.4.1_05)"
Mime Mapping File
Returns the name of the file containing mime-mappings for the domain.
Format of the file should be: extension=mime-type
If this file does not exist, WebLogic Server uses an implicit mime-mapping set of mappings defined in weblogic.utils.http.HttpConstants (DEFAULT_MIME_MAPPINGS). To remove a mapping defined in implicit map just set it to blank.
When OptimisticSerialization is turned on, WebLogic server does not serialize-deserialize context and request attributes upon getAttribute(name) when a request gets dispatched across servlet contexts. This means you will need to make sure that the attributes common to Web applications are scoped to a common parent classloader (they are application-scoped) or placed in the system classpath if the two Web applications do not belong to the same application. When OptimisticSerialization is turned off (which is the default) WebLogic Server does serialize-deserialize context and request attributes upon getAttribute(name) to avoid the possibility of ClassCastExceptions. The value of OptimisticSerialization can also be overridden for specific Web applications by setting the optimistic-serialization value in weblogic.xml.
Error on Name request time value
Global property which determines the behavior of the JSP compiler when a jsp:param attribute "name" has a request time value. Without this property set to "true", the JSP compiler throws an error for a JSP using a request time value for the "name" attribute as mandated by the JSP 2.0 spec. This property exists for backward compatibility.
Client Cert Proxy Enabled
Specifies whether or not to honor the WL-Proxy-Client-Cert header coming with the request.
Http Trace Support Enabled
Returns the value of HttpTraceSupportEnabled.
WebLogic Plugin Enabled
Specifies whether or not the proprietary WL-Proxy-Client-IP header should be honored. (This is needed only when WebLogic plugins are configured.)
Auth Cookie Enabled
Whether authcookie feature is enabled or not.
Indicates whether the session ID should include JVM information. (Checking this box may be necessary when using URL rewriting with WAP devices that limit the size of the URL to 128 characters, and may also affect the use of replicated sessions in a cluster.) When this box is selected, the default size of the URL will be set at 52 characters, and it will not contain any special characters.
The amount of time this server waits between receiving chunks of data in an HTTP POST data before it times out. (This is used to prevent denial-of-service attacks that attempt to overload the server with POST data.)
Maximum Post Time
Max Post Time (in seconds) for reading HTTP POST data in a servlet request. MaxPostTime < 0 means unlimited
Maximum Post Size
The maximum post size this server allows for reading HTTP POST data in a servlet request. A value less than 0 indicates an unlimited size.
WorkContext Propagation Enabled
Indicates whether or not WorkContextPropagation is enabled. By default it is turned on. There is a little overhead involved in propagating WorkContexts. Therefore, if you don't care about WorkContext propagation, turn this value off in production environments.
P3P Header Value
Returns the P3PHeader value that will be sent with all responses for http requests (if non-null). The value of this header should set to the location of the policy reference file for the Web site.
For details see: http://www.w3.org/TR/p3pdeployment#Locating_PRF
Alternatively, a servlet filter can be used to set the P3P header.
JSP Compiler Backwards Compatible
Global property to determine the behavior of the JSP compiler. When this property set to "true", the JSP compiler throws a translation error for JSPs that do not conform to the JSP2.0 specification. This property exists for backward compatibility.
