Re: SISCweb & File Upload

I've been doing a few tests and I have a problem. In order to be able
to upload files y must declare the form's enctype to be
multipart/form-data:

(form (@ (action ,k-url) (enctype multipart/form-data)) ...

But, once I do this, get-bindings isn't able anymore to extract the
bindings from the request object. It just returns an empty map.
