(1) from A site (http) can launch and communicate with swf in B site (http)

(2) after install SSL, A site can support both http and https

from A site (https) can launch and communicate with swf in B site  
but from A site (http) cannot communicate with swf in B site. Everything works fine except the communcation with swf file.

What is the problem??

I’m using IE8, A site and B site are IIS, crossdomain.xml is

\<?xml version=“1.0”?\>  
\<!DOCTYPE cross-domain-policy SYSTEM “[http://www.adobe.com/xml/dtds/cross-domain-policy.dtd](http://www.adobe.com/xml/dtds/cross-domain-policy.dtd)”\>  
\<cross-domain-policy\>  
\<site-control permitted-cross-domain-policies=“all” /\>  
\<allow-access-from domain="_" secure=“false”/\>  
\<allow-http-request-headers-from domain="_" headers="\*" secure=“false”/\>  
\</cross-domain-policy\>
