![]() Set to false (the default) in security conscious environments, to make getContext() always return null. Set to true if you want calls within this application to ServletContext.getContext() to successfully return a request dispatcher for other web applications running on this virtual host. Set to false if you want to disable the use of cookies for session identifier communication, and rely only on URL rewriting by the application. Set to true if you want cookies to be used for session identifier communication if supported by the client (this is the default). If not specified, no filtering will be applied. Matching uses .find() so the regular expression only has to match a sub-string of the fully qualified class name of the container provided SCI for it to be filtered out. ![]() The regular expression that specifies which container provided SCIs should be filtered out and not used for this context. ![]() If not specified, the standard value (defined below) will be used. This class must implement the interface. Java class name of the implementation to use. If not specified, the default value for this attribute is -1, which means the context will rely on the background processing thread of its parent host. A context will use background processing to perform session expiration and class monitoring for reloading. After waiting the specified amount of time, the thread will invoke the backgroundProcess method on this host and all its child containers. Setting this to a positive value will cause a thread to be spawn. Child containers will not be invoked if their delay value is not negative (which would mean they are using their own processing thread). This value represents the delay in seconds between the invocation of the backgroundProcess method on this context and its child containers, including all wrappers. Note that any setting other than false causes Tomcat to behave in a way that is not technically spec-compliant. Set to true if Tomcat should automatically parse multipart/form-data request bodies when HttpServletRequest.getPart* or HttpServletRequest.getParameter* is called, even when the target servlet isn’t marked with the annotation (See Servlet Specification 3.0, Section 3.2 for details). In the $CATALINA_BASE/conf/// file: the Context element information will be loaded by all web applications of that host.In the $CATALINA_BASE/conf/context.xml file: the Context element information will be loaded by all web applications.The application will override all that’s defined in this file. The Default Context elements may be defined for multiple web applications and these can be configured individually. Valve – specifies the connection tracker for the web application lifecycle.Manager – specifying this will disable session persistence across tomcat restarts.WatchedResource = “web.xml” – we are setting this context.xml to monitor the changes made to the web.xml of the application being deployed.Context reloadable = “true” and privileged = “true” – to enable reloading and invoker servlet and cgi support.Once Catalina has matched a context with a request, the selected Context passes the request to the correct servlet to process the request, based on definitions contained in the web application deployment descriptor file. Tomcat lets you save complete server configuration profiles, and apply them to new instances with a single click. Applications can either be stored in a Web Application Archive (WAR) file, in which case they will be dynamically uncompressed as needed, or as organized unpacked resources in a directory.ĭon’t do the same Context configuration work twice. The context path, which is contained within the context, specifies where the application’s resources can be located. There is no limit to the number of Contexts that can be defined, as long as each Context is given its own unique context path. Once a Context has been defined, Catalina will attempt to match incoming HTTP requests to its context path. For each explicitly configured web application, there should be one context element either in server.xml or in a separate context XML fragment file. A web site is made up of one or more Contexts. In Tomcat, the Context Container represents a single web application running within a given instance of Tomcat.
