Loading XML from ASP - what gives?

trying to get xml generated by an .aspx page (located in another domain) into flash.

I’m able to load it easily when i test within Flash. The data loads almost instantaneously.

As soon as I use a proxy file (PHP, because i’m not able to get my domain added to their cross-domain policy file) to load the data (all files being on my webserver), the load slows down to take up to two minutes.

why am i seeing such a huge descrepancy between local testing and ‘live’ server load times?

is the php proxy file the culprit?

if i hit the .aspx URL directly, i am able to download an xml file which is approximately 3k… this is pretty much instantaneous as well.

seems strange that the .aspx script can produce an xml file as well as plain old xml (it’s actually SDMX-ML)… haven’t encountered that type of capability yet…

anyhow, if anyone has any insight into xml load time and local vs. live load time, that would be great…
