I would like to see the possiblity to resume broken uploads.

I've added support for download managers long time ago. This also included 
support for http range in downloads, so as far as I know this should be enough.

To try with download managers (like DownThemAll), add following client setting 
(in host page init):

expose-file-links: true

For example:

            mollify.init({
                "service-path": "backend/",
                "expose-file-links": true
            });

No.. not downloads.. i mean uploads!
When Uploading Files TO mollify via Webinterface.. there would be nice to have 
a resume function

Oh sorry, didn't read it carefully.

Resuming uploads is a whole another story. Basic HTTP upload does not support 
this, but third party uploaders like Plupload could, but not sure if they do. I 
have to investigate it a bit more.

Yes but for example the Windows WedDAV Client 'BitKinex' also support via 
WebDAV resume of upload via this "Content-Range" thing.. i dunno exactly.. but 
we would really need this.. maybe i can get in touch with you via mail ?

Sure, but the difference is that you were asking about web interface used with 
a browser, not a dedicated standalone client like the WebDAV client.

My point was that browsers (or the HTTP standard) don't have resume upload 
support, that's why I said we need some third party uploader that support it. 
So far I don't know any, for example couldn't find any mention in Plupload for 
it supporting this.

In the server side this isn't a problem, I could add the support if there was a 
component in client side making this possible.

I think GEARS supports that:

Maybe you can implemtent it already for WebDAV ? So i could use it via BitKinex 
:)

Gears is, or more like was, interesting concept. But it's not supported any 
longer: http://gearsblog.blogspot.com/2010/02/hello-html5.html

But just like they pointed out, HTML 5 has many of the things, and HTML 5 File 
API does look promising (http://dev.w3.org/2006/webapi/FileAPI/). I've have to 
investigate more about this part.

What comes to WebDAV, sure I could add resume upload support, but can't find 
any fact that the SabreDAV supports it either 
(http://code.google.com/p/sabredav/). This is the lib that provides the DAV 
protocol, and the support must be there in the first place.

It seems like HTML5 actually does make this possible. However, it means that I 
have to create the uploader myself, which will take some time. It's pity that 
plupload does not have this, as it's so powerful uploader in all other aspects.

Also, HTML5 is not yet supported that well, I guess only Chrome and Firefox 4 
works well enough at the time.
