Removal of the /var/www/icons alias from Apache config [closed]
Most icons are used for displaying file types in directory listings. If you do not use such listings, you can safely remove alias + files. I did so and do not miss them.
It is for sure safe to remove it. Other conf files could reference /icons (e. g. the autoindex module) but apart from some not found errors nothing nasty should happen.
My advice: scan the access.log files to see if urls rooted at /icons are accessed. Delete the alias and monitor the error.log file for 404 errors.
