Issue

Adobe Flash Media Server (FMS) returns the following by default for crossdomain.xml requests: 

<cross-domain-policy>
		
	<allow-access-from domain="*">
		
	<site-control permitted-cross-domain-policies="master-only">
		
	<?xml version="1.0" encoding="utf-8" ?> 
		
	<cross-domain-policy>
		
	  <allow-access-from domain="*" /> 
		
	<site-control permitted-cross-domain-policies="master-only" /> 
		
	</cross-domain-policy>

Some administrators may want to change this default behavior and use a custom crossdomain.xml policy file.

Reason

FMS typically does not require a crossdomain.xml policy file. However, when Adobe Flash Player makes some HTTP requests (non-RTMPT) to FMS (e.g. /fcs/ident, /fcs/uInfo, etc.), it will request a crossdomain.xml. For this reason, FMS has a default, built-in crossdomain.xml. This crossdomain.xml can be overridden.

Solution

Override the default by specifying the absolute path to a separate crossdomain.xml in Server.xml:

  1. Stop FMS.
  2. Back up fms_root/conf/Server.xml, then open the file in a text editor.

  3. Specify the absolute path to the crossdomain.xml in the <CrossDomainPath> tag. For example:

    <Root><Server><CrossDomainPath>C:\Program Files\Adobe\Flash Media Server 3\conf\crossdomain.xml</CrossDomainPath>
  4. Save the Server.xml file and start FMS.
