Question

Answer 1

You cannot able to find very simple.

Because every website using their own way of techniques. You need to do for individual website.

Check the Request.Method = "POST"

As far we detected few websites

Samples below :

// Dropbox uses chunks of octet-stream requests:

  if (url.Contains("/chunked_upload?") && url.Contains("chunk=0"))
  {
       //File Upload through this URL       
  }

// Yahoo uses savewithattachment method

 if (url.ToLower().Contains("savewithattachment"))
 {
 //File Upload through this URL  
 }

// Office365 Uses

 if (url.ToLower().Contains("createattachment"))
 {
 //File Upload through this URL  
 }
