Is it possible to pull the file name from a WWW get?

Actually there is no "filename". You send a get request to a server for a specific resource (your URL) and the server returns that resource. It doesn't have to be a file. It could be some data from a database, so there's no filename. HTTP doesn't really support a way to give the resource a "name".

Most browsers however support reading an additional Content-Disposition header which is actually not part of HTTP. If the server adds such an header you might read the possible filename from there, but most servers don't include that header.

An HTTP response just consists of:

• the status line

• additional headers

• (an empty line)

• the data

There are only a few response headers and "Content-Disposition" is the only one that even mentions a filename. So in most cases you would either:

• extract the filename from the Content-Disposition header if available

• extract the filename fromt the request URL which is a bit tricky since you will have a hard time to decide what is a filename and what not.

• generate your own random filename (like Unity does when dragging images from the browser into Unity).

It's actually just one more step after pulling the object. In this example, I'm asking for the name of the www.texture

 using UnityEngine;
     using System.Collections;
     
     public class Example : MonoBehaviour {
         public string url = "http://images.earthcam.comec_metrosourcams/fridays.jpg";
         IEnumerator Start() {
             WWW www = new WWW(url);
             yield return www;
             renderer.material.mainTexture = www.texture;
             Debug.Log("Texture Name: " + www.texture.name);
      }   
     }
