There's no explicit function to do this, but it looks like the content
retrieval functions (_IG_FetchXmlContent, etc.) return a JS null for
their data parameters when an error occurs, including no connection.
So you'd code it something like this:
_IG_FetchXmlContent(url, callback);
function callback(xml)
{
if (xml == null)
{
// No connection
}
else
{
// Retrieved OK
}
};
