Example URL:
http://host2-netlabs.rhcloud.com/

Steps to reproduce the problem:
I’ve created a reproduction available to SAP-externals. (externally hosted & no authentication required)
Simply open this link in Chrome or Firefox to reproduce the issue: 
http://host2-netlabs.rhcloud.com/

The cookies are only missing if the font is loaded from a different host.
If the fonts come from the same host the cookies are sent as well. 
Use this link and check the network tab to see the cookie:
http://host1-netlabs.rhcloud.com/

The two websites will load two font files from host1.
The second font file will only be returned by the server-side request handler, if a cookie is set (any cookie will be accepted, for the sake of simplicity).

see description in attachment "Chrome_icon_font_issue_description.docx"

What is the expected behavior?
Icon-Font is requested with cookie in request header

What went wrong?
Cookie is not sent with request header and therefore some reverse proxies doesn't provide the icon-font. 

Did this work before? N/A
