301 redirects for all except me
I've been developing a new version of my website for a while now, on a different directory to my currently-live website.
Shortly I'll be ready to move this directory to root and do a mass search and replace on the database dump.
However, for the short period whilst I take the old files offline and put the new site in place - and test it to make sure everything is working correctly - I'd like to put up a "coming soon, version 2 of the website!" image to all users apart from myself.
When I access the website, I want to be able to see everything as usual so that I can work on it.
What's the best way to go about this?
Thanks in advance,
