1. Backend:<br>
(1)API definition:<br>
POST /storagepools/isos/storagevolumes/upload {'file':
fileobject} -- This is from backend view, as cherrypy's embedded
support wraps fileobject.<br>
REF:<tt><big><big><a moz-do-not-send="true"
class="moz-txt-link-freetext"
href="http://docs.cherrypy.org/en/latest/pkg/cherrypy.tutorial.html?highlight=upload">http://docs.cherrypy.org/en/latest/pkg/cherrypy.tutorial.html?highlight=upload</a></big></big></tt><tt><big><br>
<br>
(2) implementation:<br>
We can get the file handler from cherrypy's embedded
scheme, and use it to read and write to a local file, ref:<br>
<a moz-do-not-send="true"
class="moz-txt-link-freetext"

The only thing we need to concern at backend is the
file size, cherrypy demo has proposed a example leverage cgi
lib:<br>
<a moz-do-not-send="true"
class="moz-txt-link-freetext"
href="http://tools.cherrypy.org/wiki/DirectToDiskFileUpload">http://tools.cherrypy.org/wiki/DirectToDiskFileUpload</a></big></tt><br>
<br>
<br>
2. For UI, we need to supply user with a form which input type
is 'file', or we construct formdata in ajax(for IE only
supported in IE10+):<br>
REF: <tt><br>
<a moz-do-not-send="true"

<br>
<big>3. To support the progress bar in UI, we can utilize
resumable js: </big></tt><a moz-do-not-send="true"
class="moz-txt-link-freetext"

<br>
About the progress bar, we need to store it on backend to make
this info available to all users.<br>
I think we can use the same approach to upload/download.<br>
