Question

I keep getting this warning

Resource interpreted as Font but transferred with MIME type application/octet-stream: “http://127.0.0.1:8080/assets/font/fontawesome-webfont.woff”.

I am using Play 2.0.4 webserver. I added the mime-types to my application.conf file as follows

mimetype.eot = application/vnd.ms-fontobject
mimetype.otf = application/octet-stream
mimetype.ttf=application/x-font-ttf
mimetype.woff = application/x-font-woff

Any idea what I may be doing wrong.

Actually, I found the answer:

Some browsers, like Google Chrome, will show this warning when a font
is downloaded from a web server that sets an unexpected MIME type for
fonts.

For many font types, there is a solution!

Update the configuration for your web server with the following MIME
type per font file extension:

.ttf — font/truetype 
.otf — font/opentype 
.eot — application/vnd.ms-fontobject 
.woff — application/x-font-woff 

If you
are using Apache configuration, you may include the AddType directive
for each font type:

AddType application/vnd.ms-fontobject eot
AddType font/truetype ttf
AddType application/x-font-woff woff
AddType font/opentype otf

With a specific MIME type configured per font, and not the generic
application/octet-stream MIME type, you should no longer see a warning
in your web browser console.

This configuration — while effective for cleaning up your console —
does not include the technically correct MIME type for fonts like OTF,
TTF, and WOFF. For these font types, an official MIME type has not
(yet) been approved. An official type for WOFF — application/font-woff
— has been requested.AddType font/opentype otf
