CFWebsocket Cross Domain? - coldfusion

Question

Does anyone know if the new websockets feature in CF10 can be used cross domain and cross server? And does anyone know or have some sample code to do this?
I have a simple live help chat working on my app but I want to apply it to other sites and have one central admin chat area where the support agents will interact with users cross domain.

As far as I know they do not. You can, however, use a <cfhttp> to call a file on the other site that will publish the message. Here is I accomplished this.
Create a file called socketPublisher.cfm and save it in a directory that does not require a login access a file.
socketPublisher.cfm
<cfparam name="Request.Attributes.msgType" default="newJob">
<cfparam name="Request.Attributes.channel" default="notify">
<cfparam name="Request.Attributes.Type" default="">
<cfoutput>
<cfswitch expression="#Request.Attributes.Type#">
<cfcase value="yourType">
<cfscript>
WSPublish('chat',{message: '', msgType: '#Request.Attributes.msgType#'});
</cfscript>
</cfcase>
<cfdefaultcase>
<cfscript>
WSPublish('#Request.Attributes.channel#',{message: '', msgType: '#Request.Attributes.msgType#'});
</cfscript>
</cfdefaultcase>
</cfswitch>
</cfoutput>
Then in you action page on the other site, you will need to make your http request to that file.
actionPage.cfm
<cfhttp method="Post" url="#socketURL#/_scripts/socketPublisher.cfm">
<cfhttpparam type="URL" name="msgType" value="pendingFiles">
</cfhttp>
That should do it.
There is also a know issue with CF10 WSPublish that it will change the CGI scope cause error when trying to do a redirect from an action page. I am using this as a workaround for that issue until I can find a better solution.
