[Dancer-users] Handling file uploads

[Stefan Oberwahrenbrock]

Hi Sunnavy,

just to give you a short feedback (better late than never ;-) ): You are 
right, using "request->body()" worked for me.  I simply misinterpreted 
the documentation thinking  that "upload" would provide access to any 
uploads. But - as the documentation says - it provides access to 
POST-Uploads. PUT-Uploads obviously are something different.

Thanks,
Stefan
