Simple Instructions:
Access the "Mirror" view by clicking its tab. The top half of the screen shows the downloading controls. The bottom half is initially empty, but will show a list of pending downloading jobs if there are some.
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, which only that collection can access files from. 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, "Source URL", 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 deep to go when downloading: 0 means follow no hyperlinks and grabs just the
target resource. The depth limit is
ignored when downloading media other than html pages. Use the "Destination Folder" radio
button control to choose whether the files are cached into the shared public
folder or the private collection-specific folder (if available). Next, there are four checkbox controls which can be set to turn on the specified feature for a specific download. A fifth checkbox control "Automatically remove failed downloads..." does not pertain to a specific download, but instead clears the list of any failed download information, and prevents any future failures from appearing in the list. 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 "Automatically remove failed downloads..." checkbox).
Advanced Instructions:
The Preferences section describes how to establish an Internet connection
via a proxy. If authentication is needed, the proxy server prompts for
identification and password. The Librarian Interface does not store passwords
between sessions.
