Blueimp, backload and file extesion restriction

Question

I'm using Blueimp and Backload to handle file uploads in my asp.net application. I know how to restrict file extensions by doing something like:

<input type="file" name="files[]" accept="image/png" multiple>

But I also need to validate the file extension in the server side before writing it to disc.

Any tip is appreciated.

Seems, this will be implemented in the coming release: https://github.com/blackcity/Backload/wiki/Release-notes#1940-current-dev

Meanwhile use the workaround described here: https://github.com/blackcity/Backload/issues/32
