* The appropriate mimetype is calculated based on filename extension.

* The URL to the servlet should be generated thus:

* <pre>/alfresco/guestDownload/attach/workspace/SpacesStore/0000-0000-0000-0000/myfile.pdf</pre>
|

* or

* <pre>/alfresco/guestDownload/[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>
|
||||
* This servlet only accesses content available to the guest user. If the guest user does not
|
||||
* have access to the requested a 403 Forbidden response is returned to the caller.
|
||||
* <p>
|

* This servlet does not effect the current session, therefore if guest access is required to a
