Remote XML causes Exception Permission denied to call method XMLHttpRequest.open

Question

Im using google page creator to host my domain, they don't
allow javascript or xml files (the correct mime type/content type
isnt presented so the browser just downloads the file). They do
however support html. I have uploaded the main html page to their
and the javascript files and xml files to my isp that allow .js
& .xml. However, when I call it I get a nice exception.
Exception caught while loading
http://www.logics.eclipse.co.uk/portfolio.xml:
Permission denied to call method XMLHttpRequest.open.
Any ideas how to get this working - full source to test is at

Cheers
Chris

Answer 1

I'm getting really frustrated by the inability to pull files
from another domain. I downloaded DW and am testing with Spry to
pull property info from a remote site which has dynamic xml files.
It seems incredibly silly to allow http requests to load data if
you can't do it across domains. I just don't see the point. I just
checked your test url fingersuk and I see you stil don't have a
fix.
It seems pointless to me that you need to set up a CF or PHP
script to pull the remote files to your local server as a proxy!
Surely that defeats the purpose of the whole Spry http request
idea. It's creating more work instead of saving it. Maybe I'm
missing something, it's late and I'm tired and frustrated!
Is it possible to use a domain policy XML file or something
with Spry to include an IP in a sites 'trusted realm'?
