display in browser via http

I can get the following file to display properly in a browser (latest IE), however when accessed via a request to the server (http://www.smoky-hills.com/custer_st_park.svg), I get an error.
Any help is appreciated.

Best.... Travis

I think that your server don't send correct mimeType for file with svg extension.
MimeType must be image/svg+xml

If server is Apache, add file named htaccess with :
AddType image/svg+xml svg
AddType image/svg+xml svgz
