Azure bootstrap fonts

Question

Can't seem to solve this, im pusing a custom bootstrap css&fonts into my azure cdn but in chrome I keep getting "Font from origin 'http://azxxxxxx.vo.msecnd.net' has been blocked from loading by Cross-Origin Resource Sharing policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost.domain:16300' is therefore not allowed access.

I modified my bootstrap css

font-face {
  font-family: 'Glyphicons Halflings';

  src: url('//azxxxxxx.vo.msecnd.net/fonts/glyphicons-halflings-regular.eot');
  src: url('//azxxxxxx.vo.msecnd.net/fonts/glyphicons-halflings-regular.eot?#iefix') format('embedded-opentype'), url('//azxxxxxx.vo.msecnd.net/fonts/glyphicons-halflings-regular.woff') format('woff'), url('//azxxxxxx.vo.msecnd.net/fonts/glyphicons-halflings-regular.ttf') format('truetype'), url('//azxxxxxx.vo.msecnd.net/fonts/glyphicons-halflings-regular.svg#glyphicons_halflingsregular') format('svg');
}

I've read a few stackoverflow posts, added the following to my webconfig

    <httpProtocol>
          <customHeaders>
              <add name="Access-Control-Allow-Origin" value="*" />
            </customHeaders>
        </httpProtocol>
 <staticContent>
      <mimeMap fileExtension=".woff" mimeType="application/octet-stream" />
    </staticContent>

Still have the same issue, any ideas?

Assuming you've uploaded fonts/CSS to Azure Storage fronted with Azure CDN.

You need to enable CORS on the storage to allow your site to access fonts cross-domain.

The complete steps are covered in Windows Azure Storage: Introducing CORS

Partial sample from the article (you'll need to get NuGet for recent Azure client libraries to build it):

private static void InitializeCors()
{
  // CORS should be enabled once at service startup
  // Given a BlobClient, download the current Service Properties 
  ServiceProperties blobServiceProperties = BlobClient.GetServiceProperties();
  ConfigureCors(blobServiceProperties);
  BlobClient.SetServiceProperties(blobServiceProperties);
}

private static void ConfigureCors(ServiceProperties serviceProperties)
{
  serviceProperties.Cors = new CorsProperties();
  serviceProperties.Cors.CorsRules.Add(new CorsRule()
  {
     AllowedHeaders = new List<string>() { "*" },
     AllowedMethods = CorsHttpMethods.Get | CorsHttpMethods.Head,
     AllowedOrigins = new List<string>() { "*" },
     ExposedHeaders = new List<string>() { "*" },
     MaxAgeInSeconds = 1800 // 30 minutes
 });
}
