Since last week, we have been seeing increased number of 404s due to customer browsers requesting urls like www.mydomain.com/adimages
. There is no pattern of User agent, IPs, OS etc., I am thinking this is more to do with the users browser plugin. But couldn't tell how all of the sudden these plugins could be requesting wrong URLs.
I verified the ADblock settings in my browser and see that there is afilter option for *-adimage-*. Since this setting is present in adblock settings, I assume this is a known url that adblock wants to block; But I couldn't still tell how the end-users of my site are getting these URLs and how all of a sudden it started since last week.
Any one has come across such request URLs containing /adimages?
