| 75 | 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.
|
|---|
| 76 | <p></p>
|
|---|
| 77 | Files are downloaded into a folder in the workspace tree called "Public
|
|---|
| 78 | WebCache" (only present when mirroring is enabled), and can be used in all
|
|---|
| 79 | collections built with the Librarian Interface. When a collection is open a
|
|---|
| 80 | second folder, "Private WebCache", appears, which only that collection can access files from. Files in both these areas are named by their full web
|
|---|
| 81 | URL. A new folder is created for each host, followed by others for each part
|
|---|
| 82 | of the path. This ensures that each file is distinct.
|
|---|
| 83 | <p></p>
|
|---|
| 84 | Use the first of the download configuration controls, "Source URL", to enter the URL of a
|
|---|
| 85 | target resource. If you have come from the "Hunt" view, this field points to
|
|---|
| 86 | the last page visited. Use the "Download Depth" control to determine how many
|
|---|
| 87 | hyperlinks deep to go when downloading: 0 means follow no hyperlinks and grabs just the
|
|---|
| 88 | target resource. The depth limit is
|
|---|
| 89 | ignored when downloading media other than html pages. Use the "Destination Folder" radio
|
|---|
| 90 | button control to choose whether the files are cached into the shared public
|
|---|
| 91 | 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
|
|---|
| 92 | settings.
|
|---|
| 93 | <p></p>
|
|---|
| 94 | The download list has an entry for each unfinished download. For each entry, a
|
|---|
| 95 | central region with several lines of text and a progress bar is flanked by two
|
|---|
| 96 | buttons. The text gives details of the task, and updates as the task
|
|---|
| 97 | progresses, while the bar measures progress. The "play" triangle on the left
|
|---|
| 98 | button starts the current task and then changes to a double vertical bar, which
|
|---|
| 99 | pauses the current download. The "stop" square on the right button removes the
|
|---|
| 100 | current download task from the list. Download tasks are removed from the list
|
|---|
| 101 | when they finish successfully (ones that fail are controlled by the "Automatically remove failed downloads..." checkbox).

| 105 | The <a href="preferences.htm#preferences">Preferences section</a> describes how to establish an Internet connection
|
|---|
| 106 | via a proxy. If authentication is needed, the proxy server prompts for
|
|---|
| 107 | identification and password. The Librarian Interface does not store passwords
|
|---|
| 108 | between sessions.
