/**
|
|
* Servlet responsible for streaming node content from the repo directly to the response stream.
|
|
* The appropriate mimetype is calculated based on filename extension.
|
|
* <p>
|
|
* The URL to the servlet should be generated thus:
|
|
* <pre>/alfresco/download/attach/workspace/SpacesStore/0000-0000-0000-0000/myfile.pdf</pre>
|
|
* or
|
|
* <pre>/alfresco/download/direct/workspace/SpacesStore/0000-0000-0000-0000/myfile.pdf</pre>
|
|
* or
|
|
* <pre>/alfresco/download/[direct|attach]?path=/Company%20Home/MyFolder/myfile.pdf</pre>
|
|
* The protocol, followed by either the store and Id (NodeRef) or instead specify a name based
|
|
* encoded Path to the content, note that the filename element is used for mimetype lookup and
|
|
* as the returning filename for the response stream.
|
|
* <p>
|
|
* The 'attach' or 'direct' element is used to indicate whether to display the stream directly
|
|
* in the browser or download it as a file attachment.
|
|
* <p>
|
|
* By default, the download assumes that the content is on the
|
|
* {@link org.alfresco.model.ContentModel#PROP_CONTENT content property}.<br>
|
|
* To retrieve the content of a specific model property, use a 'property' arg, providing the workspace,
|
|
* node ID AND the qualified name of the property.
|
|
* <p>
|
|
* Like most Alfresco servlets, the URL may be followed by a valid 'ticket' argument for authentication:
|
|
* ?ticket=1234567890
|
|
* <p>
|
|
* And/or also followed by the "?guest=true" argument to force guest access login for the URL. If the
|
|
* guest=true parameter is used the current session will be logged out and the guest user logged in.
|
|
* Therefore upon completion of this request the current user will be "guest".
|
|
* <p>
|
|
* If the user attempting the request is not authorised to access the requested node the login page
|
|
* will be redirected to.
