<p>What’s the difference between <code>Response.Write()</code> and <code>Response.Output.Write()</code>? </p>

Nothing really.
But.
```
Response.Write
```
takes the stream in the
```
Response.Output
```
property. You could set another Output stream, and in that way instead of writing back to the client, maybe write to a file or something crazy. So thats there relation.
