Crossdomain.xml and suppress server name

I have SparkWeb installed on an external web server and it works fine using sockets to my OpenFire server. I would rather use http binding with ssl, but I am running into an issue with the crossdomain.xml file that OpenFire serves.

If I go to :8888/crossdomain.xml, I get a valid file:

<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "[http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd](http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd)">
<cross-domain-policy>
<site-control permitted-cross-domain-policies="all"/>
<allow-access-from domain="*" to-ports="5222,5223,8888,7171" secure="true"/>
</cross-domain-policy>

When I go directly to 7171, I do not get a file. If I trace the action in Firebug,
I can see that it is getting hung up on the file as well.

As a second, smaller, thing, I'd like to hide the server name on the login page.
Is it possible to do so without modifying the flash files?

Thanks
