x-site cometd

[vetal]

Hi all!
I have a questions about cross-domain requests. In my project need use
two servers (PC) on first server be service with main business logic
that work on Tomcat, on other server be Jetty with cometd for sending
message to client. So client need do cross-domain XmlHttpRequest.

If i use prototype.js with plugin for cross-domain XmlHttpRequest did
it work fine for me, this plugin support only GET method?
I try use dojo for that but in README file found next :
>The current implementation destroys the iframes used for a
request after the request
>completes. This seems to cause a memory leak, particularly in
IE. So, it is not
>suited for doing polling cross-domain requests.

If any one know something about it or do something like that please
help?

Thanks,
Vetal
