I'm implementing a site that allows users to switch stylesheets (to show a high contrast version for people with vision impairments). The switcher essentially just changes the
<link>ref to whichever stylesheet is appropriate.
However, I've just realised that this will lead to problems when I switch on caching (either using WP Supercache or W3 Total Cache) - as only one version of the page will be cached and thus displayed to the user.
Any thoughts on possible solutions?
