<p>A component manager receives requests for component updates from a variety of sources, parses the requests and extracts URL information that identifies the location of a file containing the component resources. The component manager presents the URL to a download manager that asynchronously retrieves the component resources from the specified location and places the file in a staging area. Once the component resources have been downloaded, an install manager, also operating asynchronously from the component manager and the download manager, installs the component update.</p> |
