I have been developing some interactive SVG running under WEBrick.  
Works fine until the site goes under SSL. At that point my Javascript  
code fails to return a document using either contentDocument, or  
getSVGDocument(). I don’t really understand the fix, but following a  
hint from a list back in 2007, everything works again when i put the  
following line in httputils.rb. On my installation that is at

/usr/lib/ruby/1.8/webrick/httputils.rb

```
  "svg" => "image/svg+xml",

```

added into the object DefaultMimeTypes.

Here is the header to httputils.rb

Perhaps this will help someone out there in future.
