Usage

Quick Start

By default, the middleware will use a (*) wildcard for the domain value.

var crossDomainXML = require('crossdomain-xml');
app.use(crossDomainXML);

will output:

<cross-domain-policy>
 <allow-http-request-headers-from domain="*" headers="*"/>
 <site-control permitted-cross-domain-policies="all"/>
 <allow-access-from domain="*"/>
</cross-domain-policy>

Use a specific domain

Or, pass a domain to the middleware function to use as the domain value.

var crossDomainXML = require('crossdomain-xml');
app.use(crossDomainXML('*.example.org'));

which will output:

<cross-domain-policy>
 <allow-http-request-headers-from domain="*.example.org" headers="*"/>
 <site-control permitted-cross-domain-policies="all"/>
 <allow-access-from domain="*.example.org"/>
</cross-domain-policy>
