β | |Like many {{w|Web server|web servers}}, Apache keeps a record of incoming requests -- both successful and unsuccessful -- in various log files. A conscientious webmaster will often review those logs, either to gauge interest in visited pages, or more importantly to detect failed requests that should not have failed, perhaps due to errors in the site's hotlinks which are therefore in need of cleanup. If you know a particular webmaster who does this regularly, you can therefore send him/her a personal message by attempting to fetch a deliberately-nonexistent URL like <tt>http://example.com/Hey_Sandra_its_Pierce_wanna_have_a_drink_tonight.html</tt>, knowing that the "message" will show up as a failed request in the logs.

This is a form of "back channel" communication, hardly practical as a true "chat system", although an excellent in-joke among like-minded hackers. Nevertheless, shortly after this comic appeared, a more "practical" implementation was [https://github.com/mdom/smokesignal published on github]. |
