clueless as to how this is happening....
my website uses htaccess to nicely handle 404s - and a little code ont he 404 page emails me if one is generated. This is so if I put up a bad link I'll know pretty quick.
But recently, whenever a 404 occurs I immediately get another alert for the same non-existent page - always from the same IP.
I'm really curious to know how this other 404 source is getting the information to try the non-existent address that someone else mistyped?
Any thoughts as to how, or, just as usefully, where else I can ask this question?
I've replicated this behaviour by navigating to random non-existent URIs from firefox 27 in safemode (linux), chrome33 with disable-extentions (linux) and android chrome (wifi / mobile data) so pretty sure it's not anything nasty on my side. I've grabbed the current 404 code from the site and there isnt anything in there either.
