I send to confgure - url instead of path to local file:

> Visualizer.connect({  
> application: ‘visualizer’,  
> dataFile: ‘a.vtk@[http://bioup.azurewebsites.net/a.json](http://bioup.azurewebsites.net/a.json)’,  
> dataDir: “[http://bioup.azurewebsites.net/](http://bioup.azurewebsites.net/)”  
> });

But it does not work:

Does `http:\bioup.azurewebsites.net\a.vtk` looks like a valid path on the machine where the server is running.

I’m guessing what you are asking for (without asking) is how to make ParaView load a file from a remote server by downloading it first?

Create your own RPC endpoint that will ask Python to download that file first and load it from the local file system.

If you still don’t understand what I mean, Kitware offer support contract which could allow us to help you out and even write that piece of code for you.
