Web server setting

CORS Configuration

It is required to configure the Cross-Origin Resource Sharing (CORS) for the files *.js, *.js.mem, *.json and *.data from



<IfModule mod_headers.c>

    <FilesMatch "\.(json|data|js|js\.mem)$">

           Header set Access-Control-Allow-Origin "*"









                <add name="Access-Control-Allow-Origin" value="*" />






MIME Types Configuration

The MIME type application/octet-stream should be used for the files *.js.mem and *.data.

If the content is used as cortona3d multimedia bundle, the MIME type should be additionally configured for the *.cortona3d files.



application/octet-stream            .mem

application/octet-stream            .data

application/x-zip-compressed        .cortona3d






            <mimeMap fileExtension=".mem" mimeType="application/octet-stream" />

            <mimeMap fileExtension=".data" mimeType="application/octet-stream" />
