![]() Access the "Mirror" view by clicking its tab. On the left is the workspace tree described in section 5.1 -- The Gather View. The bottom of the screen shows a list of pending download jobs. On the right are the controls used to control downloading. Files are downloaded into a folder in the workspace tree called "Public WebCache" (only present when mirroring is enabled), and can be used in all collections built with the Librarian Interface. When a collection is open a second folder, "Private WebCache", appears, associated with that collection so that it alone has access. Files in both these areas are named by their full web URL. A new folder is created for each host, followed by others for each part of the path. This ensures that each file is distinct. Use the first of the download configuration controls to enter the URL of a target resource. If you have come from the "Hunt" view, this field points to the last page visited. Use the "Download Depth" control to determine how many hyperlinks to follow when downloading: 0 means no hyperlinks and grabs just the target resource; "infinite" would grab the entire Internet! The depth limit is ignored when downloading media other than html pages. Use the next radio button control to choose whether the files are cached into the shared public folder or the private collection-specific folder. Checking "Automatically download embedded objects" also downloads any objects needed to render the page properly (irrespective of the depth setting). Use the next control to determine whether to mirror files from paths above the target URL. "Only mirror within the same site" restricts the mirroring to files with the same host name. The next control determines whether local files can be overwritten during download. The next one, in the "Download List Options" group, determines what happens to download tasks that fail for some reason. This takes effect immediately, rather than pertaining to a specific download job as the other specifications do. The final control is a "Download" button which adds to the download list a new job corresponding to the configuration settings. The download list has an entry for each unfinished download. For each entry, a central region with several lines of text and a progress bar is flanked by two buttons. The text gives details of the task, and updates as the task progresses, while the bar measures progress. The "play" triangle on the left button starts the current task and then changes to a double vertical bar, which pauses the current download. The "stop" square on the right button removes the current download task from the list. Download tasks are removed from the list when they finish successfully (ones that fail are controlled by the "Download List Options"). |
