    public interface Context
    extends Container, ContextBind
    A Context is a Container that represents a servlet context, and therefore an individual web application, in the Catalina servlet engine. It is therefore useful in almost every deployment of Catalina (even if a Connector attached to a web server (such as Apache) uses the web server's facilities to identify the appropriate Wrapper to handle this request. It also provides a convenient mechanism to use Interceptors that see every request processed by this particular web application.

    The parent Container attached to a Context is generally a Host, but may be some other implementation, or may be omitted if it is not necessary.

    The child containers attached to a Context are generally implementations of Wrapper (representing individual servlet definitions).

      • setValidateClientProvidedNewSessionId

        void setValidateClientProvidedNewSessionId​(boolean validateClientProvidedNewSessionId)
        When a client provides the ID for a new session, should that ID be validated? The only use case for using a client provided session ID is to have a common session ID across multiple web applications. Therefore, any client provided session ID should already exist in another web application. If this check is enabled, the client provided session ID will only be used if the session ID exists in at least one other web application for the current host. Note that the following additional tests are always applied, irrespective of this setting:
        • The session ID is provided by a cookie
        • The session cookie has a path of /
        Parameters:
        validateClientProvidedNewSessionId - true if validation should be applied
      • getValidateClientProvidedNewSessionId

        boolean getValidateClientProvidedNewSessionId()
        Will client provided session IDs be validated (see setValidateClientProvidedNewSessionId(boolean)) before use?
        Returns:
        true if validation will be applied. Otherwise, false
      • setMapperContextRootRedirectEnabled

        void setMapperContextRootRedirectEnabled​(boolean mapperContextRootRedirectEnabled)
        If enabled, requests for a web application context root will be redirected (adding a trailing slash) by the Mapper. This is more efficient but has the side effect of confirming that the context path is valid.
        Parameters:
        mapperContextRootRedirectEnabled - Should the redirects be enabled?
      • getMapperContextRootRedirectEnabled

        boolean getMapperContextRootRedirectEnabled()
        Determines if requests for a web application context root will be redirected (adding a trailing slash) by the Mapper. This is more efficient but has the side effect of confirming that the context path is valid.
        Returns:
        true if the Mapper level redirect is enabled for this Context.
      • setMapperDirectoryRedirectEnabled

        void setMapperDirectoryRedirectEnabled​(boolean mapperDirectoryRedirectEnabled)
        If enabled, requests for a directory will be redirected (adding a trailing slash) by the Mapper. This is more efficient but has the side effect of confirming that the directory is valid.
        Parameters:
        mapperDirectoryRedirectEnabled - Should the redirects be enabled?
      • getMapperDirectoryRedirectEnabled

        boolean getMapperDirectoryRedirectEnabled()
        Determines if requests for a directory will be redirected (adding a trailing slash) by the Mapper. This is more efficient but has the side effect of confirming that the directory is valid.
        Returns:
        true if the Mapper level redirect is enabled for this Context.
      • setUseRelativeRedirects

        void setUseRelativeRedirects​(boolean useRelativeRedirects)
        Controls whether HTTP 1.1 and later location headers generated by a call to HttpServletResponse.sendRedirect(String) will use relative or absolute redirects.

        Relative redirects are more efficient but may not work with reverse proxies that change the context path. It should be noted that it is not recommended to use a reverse proxy to change the context path because of the multiple issues it creates.

        Absolute redirects should work with reverse proxies that change the context path but may cause issues with the RemoteIpFilter if the filter is changing the scheme and/or port.

        Parameters:
        useRelativeRedirects - true to use relative redirects and false to use absolute redirects
      • setDispatchersUseEncodedPaths

        void setDispatchersUseEncodedPaths​(boolean dispatchersUseEncodedPaths)

      • getDispatchersUseEncodedPaths

        boolean getDispatchersUseEncodedPaths()
