Fix error "sec_error_ocsp_try_server_later" within Firefox

Getting the error below, in Firefox:


It's something to do with the way Firefox (and possibly IE) check for expired SSL certificates. To fix, edit the Apache Configuration for Pre VirtualHost Include, All Versions:

SSLUseStapling on
SSLStaplingCache shmcb:/tmp/stapling_cache(128000)

And restart Apache afterwards. Hat tip.
