Want to know what URL a proxy points to? Want to know the proxy(ies) that point to a given URL? Sure you do.
If you SSH into corn (or any of the Leland timeshares) and type:
remctl tools proxy showdest techcommons.stanford.edu
It will return:
https://www.stanford.edu/group/extech/cgi-bin/drupal/
Additionally, if you type:
remctl tools proxy showhost https://www.stanford.edu/group/extech/cgi-bin/drupal/
It will return:
techcommons
Finally, if you type:
remctl tools proxy showtype techcommons.stanford.edu
It will return:
proxy
And that's pretty nifty. (Thanks to Jon Robertson in ITS for installing the remctl tools and explaining their use.)
