I've made a Zimlet that gets some data from another web server. I wrote it on ZDesktop using openalldomains zimlet and tested it working fine, i then tested it without openalldomains (ensuring my XML was allowing the domain) and it also worked fine. I deployed it to my Zimbra Server and according to firebug, the request is shown in red and nothing is returned.
We are using a HTTP proxy with zimbra (and the client browser) if that makes any difference. RSS Feeds work fine BTW, so the proxy set up is working.
Any help would REALLY be appreciated!
