I have several local hosts set up on my dev OS X machine in my
/etc/hosts file . The browser hangs for several seconds while trying to load them. Which doesn’t make any sense, since they are local. The solution is to change the hosts file so that all hosts are on one line, the very first line where localhost is defined.
In other words, change from this…
127.0.0.1 localhost 255.255.255.255 broadcasthost ::1 localhost fe80::1%lo0 localhost 127.0.0.1 my-host.dev 127.0.0.1 another-host.dev 127.0.0.1 oh-that-host.dev
127.0.0.1 localhost my-host.dev another-host.dev oh-that-host.dev 255.255.255.255 broadcasthost ::1 localhost fe80::1%lo0 localhost
It doesn’t make sense, but it works and that’s all that matters. It’s probably an OS X bug which at some point will be fixed.
