Description Dave Jeffery 2016-08-03 06:21:29 PDT
Summary:
Localhost subdomains (i.e. 'http://mysite.localhost') don't work in Safari. They work ok in all other web browsers (Chrome, Firefox, Opera etc..).
I am not sure if this is a Safari/OS X issue or a webkit issue, feel free to close this bug report if that is the case.

Steps to Reproduce:
1. Start up a local server that responds to the host header of 'mysite.localhost' on port 8000 (any port is fine)
2. Try to access the site in safari using the url: http://mysite.localhost:8000/

Expected Results:
Every other web browser (Chrome, Firefox, Opera etc..) that I have tested will find the server and load the page as expected. Localhost subdomains don't seem to be mentioned in any official spec but the fact that they work in every other browser means that people use them for real-world development.

Actual Results:
Safari gives the error "Can't find server"

Version:
Tested on OS X 10.10 and OS X 10.11 with Safari 9.1.2.
