尝试使用curl下载文件，其中文件下载被javascript阻止？

Question

I am trying to use curl to download a torrent file the url is

http://torcache.net/torrent/006DDC8C407ACCDAF810BCFF41E77299A373296A.torrent

You will notice that upon getting to the page the download of the file is blocked for a few seconds via javascript, I was wondering if there is anyway to bypass this while using curl and php?

Thanks

The file is not blocked via javascript, that's just an informal message if you request that file. The redirect then is done via javascript.

You can simulate the request your own, the important part here is that you add the HTTP Referrer request header. Example:

$ curl -I -H 'Referer: http://torcache.net/torrent/006DDC8C407ACCDAF810BCFF41E77299A373296A.torrent' http://torcache.net/torrent/006DDC8C407ACCDAF810BCFF41E77299A373296A.torrent
HTTP/1.1 200 OK
Server: nginx/1.3.0
Date: Sun, 10 Jun 2012 17:13:59 GMT
Content-Type: application/x-bittorrent

Referrer is one thing to check, mind the typo in the HTTP specs, see Wikipedia.
