Catching links that are just a number, not an extension

[emailrob1]

Hi, I have a domain that downloads files that are shown on the website as a number, e.g. 262511

The website address is like this (example) https://torrentpage.com/torrents/262511

When the torrent downloads, it looks like this

8473-TV_Show_Name.S06E07.(Date).[720p.mp4.subs].torrent < note the number at the start appears to be a post number and not related to the torrent itself.

I can't work out how to set up a link catcher to pick it up. I checked the FAQ but that seemed to only look at the web address itself, but the address I'm using doesn't list the actual filename until the file is downloaded.

Appreciate the help and thanks for a great plugin!
