Hello Steve,
You have encountered a bug that will be fixed with the next version of
the Genome Browser CGIs, which we expect to release early next week. In
the meantime, the bug is caused by making a http request to hgTracks
without specifying a User-Agent header, so, if you set the user agent in
your program, e.g.:
curl_setopt($ch, CURLOPT_USERAGENT, "curl");
you should be able to get the requested page.
I hope this helps, and sorry for the inconvenience!
