  - Installing
    HCL Digital Experience provides flexible deployment options that range from proof-of-concept where you can examine and test functionality to a highly available and scalable production environment. Review the planning information to learn more about hardware and software requirements, high availability, scalability, supported topologies, and much more. Select your operating system and then select the installation pattern that most reflects your business needs.
  - Configuring
    Run the following tasks after you install and deploy HCL Digital Experience. They address tasks that are typically run one time and have a global effect. Some configuration changes are made more frequently or do not have a global effect. These tasks are addressed in the Administering section.
  - Backup and restore
    Backup and recovery of data files and databases is an essential operation for any business system, particularly for data and applications that run in production environments. Create and follow a plan for backing up and recovering data on all tiers of your HCL Digital Experience deployment. IBM Installation Manager must also be included in backup and recovery planning. If you back up the HCL Portal file structure and then install a fix pack, your HCL Digital Experience and IBM Installation Manager become out of sync after you restore the HCL Portal file system. This condition is not recoverable.
  - Migrating
    Successful migration requires significant planning and preparation, understanding the tools that are involved, and careful execution of the appropriate steps in the order provided.
  - Integrating
    Integrate HCL Digital Experience with software such as HCL Sametime to enable your users to collaborate more easily. You can also use the unified task list portlet to integrate HCL with your backend business process software, such as IBM Process Server.
  - Administering
    Use the administration tools that are provided with the portal to do various day-to-day administration tasks. There are two methods for editing portal setup: using the administration portlets or the XML configuration interface. The administration portlets are a convenient way to make real-time updates to the portal's configuration. While the XML configuration interface is suited to more advanced administration, including batch processing of updates.
  - Securing
    Security tasks include setting up property extension databases and custom user repositories, configuring and activating SSL, and configuring authentication. In addition, tasks such as activating Federal Information Processing Standards (FIPS) and NIST SP800-131a security modules and configuring external security managers such as Security Access Manager might be required to secure your portal environment.
  - Monitoring
    HCL Portal includes tools and features to help you monitor the portal site.
  - Setting up a website
    Setting up a website includes, creating pages, adding navigation, setting up search, and adding content to the site. Themes are used to customize the portal's look-and-feel. Out-of-the-box templates and the site wizard can help you set up your portal site faster. You can add wikis and blogs to your site and let users tag and rate content on your site.
  - Staging to production
    During portal solution development, the solution is initially developed, tested, and refined on one server or a limited number of servers. The solution is deployed later on live systems, referred to as the production environment. The process of moving the solution from the development environment to the production environment is called staging.
  - Developing
    This section includes developer documentation on extending applications and development assets for HCL Portal and HCL Web Content Manager.

    - Dojo and HCL Digital Experience
      HCL Digital Experience contains an instance of the Dojo Toolkit, a JavaScript library that is based on the Dojo Toolkit. When you develop components that use Dojo, you must be aware of how the portal uses Dojo, and the tips and restrictions when you use Dojo.
    - Extending HCL Portal class path
    - Developing themes and skins
      You can create themes using modules to contribute to separate areas of pages to provide flexibility, enhance the user experience, and maximize performance. To optimize themes on your website, use the theme optimization module framework. The framework separates feature-specific logic and capabilities from the theme code.
    - URL generation in HCL Portal
      Generating Portal URLs correctly is one of the most important tasks in programming an HCL Portal based application. There are several programming tools and techniques available for generating HCL Portal URLs in custom code. The following section introduces the programming tools available and discusses when it is most appropriate to use each of the tools.
    - Model SPI overview
      Models provide information that is needed by HCL Digital Experience to perform tasks such as content aggregation or building navigation to browse the aggregated content. The information that is aggregated is represented through models that can be accessed programmatically by using the Model SPI (read-only). The information of a model is usually persistent (stored in a database) but can also be transient (computed and stored only in memory). Models can be represented by using a tree structure (nodes have a parent-child relationship), a list structure, or a selection structure (a selected element in a tree structure).
    - Controller SPI
      You can use the Controller SPI for portal administration. It allows you to modify portal resources. It enhances the read-only portal Model SPI by adding writable aspects.
    - User and group management
      The Portal User Management Architecture (PUMA) System programming interface (SPI) provides interfaces for accessing the profiles of a portal User or Group.
    - Portal Access Control interfaces
      Portal Access Control provides interfaces for retrieving and modifying and access control information of portal resources, such as portlets or pages.

        The client side portlet programming model
        You can use the client side programming model to make use of AJAX techniques in your standard API portlets.
        Outbound HTTP connection
        Applications in your HCL Portal and the related user activities can require outbound HTTP connections to remote computer systems. The outbound HTTP connection service provides an administration infrastructure with a central point of administration for all outbound HTTP connections that are defined in the portal environment.
        The programming model for the outbound HTTP connection service
        The outbound HTTP connection service can be used from the context of a servlet request service or from the context of a portlet request service. Here are some code examples.
        HTTP proxy for Ajax applications, also known as Ajax Proxy
        One of the basic technologies that emerged in the context of the next generation web user interface is Ajax (Asynchronous JavaScript and XML). Using Ajax can increase the responsiveness and usability of your web applications.
        Configuring outbound HTTP connections
        In HCL Portal Version 8.0 and earlier versions, outbound HTTP connections were accessible through the Ajax Proxy service. The Ajax Proxy service was configured by a configuration document named proxy-config.xml. You find this document in the /WEB-INF directory of the web module that uses the Ajax Proxy service. Starting with HCL Portal Version 8.5 and the new outbound connection service, the configuration of outbound HTTP connections is now part of the standard datastore-based portal configuration.
        Authenticating outbound HTTP connections
        You can protect the access to the remote host by an authentication mechanism.
        Using dynamic elements in outbound HTTP connection settings
        In some cases, it is useful to control configuration settings at run time. For example, an administrator might want to have the program decide at run time which policy rule is applied. In another scenario, parts of a policy rule configuration that are known only at run time must be included in the configuration.
        Using programmatic extensions for outbound HTTP connections
        To extend the functions of an outbound connection, portal administrators can implement a custom outbound service filter.
        Custom outbound service filters
        Custom outbound service filters provide a plug point for application developers. They can use these filters to add custom function to the processing logic of a policy.
        Using custom cookie transformation handlers
        You can use custom cookie transformation handlers to allow custom program extensions to get programmatic control over the outbound HTTP connection.
        Migration
        HCL Portal Version 8.5 provides a migration process for the change from the Ajax proxy of previous portal versions to the new outbound HTTP connection.
        Live text for click-to-action
        HCL Digital Experience supports a live text API for user controlled data transfer between components. With live text, a component on a page can declare sources and targets for data transfer. For example, this can be a portlet or a navigation element. When the user clicks on a source element, the portal displays a menu listing targets that match the selected source. When a menu item is selected, the portal invokes the corresponding target passing it the source data. This process is called Click-to-Action (C2A).
      - Client-side aggregation reference
        Refer to programming model guidelines for client-side mode or server-side mode.

Using programmatic extensions for outbound HTTP connections | HCL Digital Experience

To extend the functions of an outbound connection, portal administrators can implement a custom outbound service filter.

About this task

For example, such access can be required in the following cases:

A portal administrator wants to open an outbound HTTP connection to a back end system that requires a specific HTTP request header setting.
A portal administrator wants to feed a third-party site analysis program with information about an outbound HTTP connection. In this case, the outbound connections service calls custom code whenever the outbound connection is opened to the specific remote site. The custom code feeds the third-party site analysis program with the information about the remote connection.
