migrating from harvard to gweep.

[naweiner]

i created a simple test php file that looks something like the following:

$url = "http://api.flickr.com/services/rest/?method=flickr.test.echo&api_key=XXXXXXXXXXXX";

$response = file_get_contents($url);

echo $response;

if i paste the url into my browser directly, i get an XML file in response.
if i call this file from a harvard server, i get an XML file in response.
if i call this file from gweep, i get nothing.

any idea why?
