They force the browser to check the files on every request, usually
using an if-modified-since conditional request which will be answered
with a 403 - not changed answer by dokuwiki.

To prevent confusion, that is a 304 response (not a 403 response).... See: http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html
