Reading the Input Stream

To upload files you use POST:

<form action="/servlet/upload" enctype="multipart/form-data"  method="post">
    Filename: <input type="file" name="file"/><br/>
    <input type="submit"/>
</form>

You can then read the raw data be getting a reader from
```
public BufferedReader ServletRequest.getReader();
```

To read binary data you use an input stream

public ServletInputStream ServletRequest.getInputStream();

The raw data from the POST above is encoded as in RFC 1867, so it needs further parsing (code in book).
