How to make client enter website from the first page?

For some special days, there are too many clients access our website. For these special days, we will design a simple home page(which contains just some link) to reduce network traffic and server loading. But some clients have bookmark some pages, then direct to these pages. So we need to let these clients that have bookmark some pages to enter website from the home page(first page).

 

Anyway, thanks a lot.
