Configuration Options

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. MBean Attribute: WebAppContainerMBean.ReloginEnabled Changes take effect after you redeploy the module or restart the server.
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. MBean Attribute: WebAppContainerMBean.AllowAllRoles Changes take effect after you redeploy the module or restart the server.
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. MBean Attribute: WebAppContainerMBean.FilterDispatchedRequestsEnabled Changes take effect after you redeploy the module or restart the server.
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. MBean Attribute: WebAppContainerMBean.OverloadProtectionEnabled
X-Powered-By Header	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)" MBean Attribute: WebAppContainerMBean.XPoweredByHeaderLevel
Mime Mapping File	Returns the name of the file containing mime-mappings for the domain. Format of the file should be: extension=mime-type Example: htm=text/html gif=image/gif jpg=image/jpeg 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. MBean Attribute: WebAppContainerMBean.MimeMappingFile Changes take effect after you redeploy the module or restart the server.
Optimistic Serialization	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. MBean Attribute: WebAppContainerMBean.OptimisticSerialization Changes take effect after you redeploy the module or restart the server.
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. MBean Attribute: WebAppContainerMBean.RtexprvalueJspParamName Changes take effect after you redeploy the module or restart the server.
Client Cert Proxy Enabled	Specifies whether or not to honor the WL-Proxy-Client-Cert header coming with the request. MBean Attribute: WebAppContainerMBean.ClientCertProxyEnabled Changes take effect after you redeploy the module or restart the server.
HTTP Trace Support Enabled	Returns the value of HttpTraceSupportEnabled. MBean Attribute: WebAppContainerMBean.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.) MBean Attribute: WebAppContainerMBean.WeblogicPluginEnabled
Auth Cookie Enabled	Whether authcookie feature is enabled or not. MBean Attribute: WebAppContainerMBean.AuthCookieEnabled Secure value: true
Change Session ID On Authentication	Global property to determine if we need to generate a new SessionID after authentication. When this property set to "false", the previous sessionID will be retained even after authorization. MBean Attribute: WebAppContainerMBean.ChangeSessionIDOnAuthentication Changes take effect after you redeploy the module or restart the server.
WAP Enabled	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. MBean Attribute: WebAppContainerMBean.WAPEnabled
Post Timeout	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.) MBean Attribute: WebAppContainerMBean.PostTimeoutSecs Minimum value: 0 Maximum value: 120 Secure value: 30
Maximum Post Time	Max Post Time (in seconds) for reading HTTP POST data in a servlet request. MaxPostTime < 0 means unlimited MBean Attribute: WebAppContainerMBean.MaxPostTimeSecs
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. MBean Attribute: WebAppContainerMBean.MaxPostSize
Work Context 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. MBean Attribute: WebAppContainerMBean.WorkContextPropagationEnabled
P3P Header Value	Returns the P3P Header value that will be sent with all responses for http requests (if non-null). The value of this header points to the location of the policy reference file for the Web site. Alternatively, a servlet filter can be used to set the P3P header. MBean Attribute: WebAppContainerMBean.P3PHeaderValue Changes take effect after you redeploy the module or restart the server.
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. MBean Attribute: WebAppContainerMBean.JSPCompilerBackwardsCompatible Changes take effect after you redeploy the module or restart the server.
Archived Real Path Enabled	Global property to determine the behavior of getRealPath() for archived web applications. When this property set to "true", getRealPath() will return the canonical path of the resource files. MBean Attribute: WebAppContainerMBean.ShowArchivedRealPathEnabled Changes take effect after you redeploy the module or restart the server.
