Cross domain communication

last week i started writing a post about cross document messaging in IFRAMES (/ objects) and XMLHTTP, today i found that Rick Strahl wrote a simple quick post about part of what i wanted to talk about - check it out and also see my additional comments on further reading.

These days the usage of mushups and enterprise UI widgets /Scripts is gaining much interest and usage, i think that every architect must know the options / high level solutions and every developer should be aware of the actual implementations that exist (and there are a lot).

Also i noticed something VERY weird in IE6+ that the same origin policy doesn't handle different ports, e.g. communication between  www.davidovitz.org/gallery and www.davidovitz.org:8080/gallery works – while fails in all other browsers
