Testing grace
=============

1. Set up two web servers (already done)
2. Normally, Varnish should balance between both
3. For /cgi-bin/, make Varnish always use Apache
4. Test the test.cgi script wit the sleep-statement
5. Make test.cgi cache, either by editing the script or forcing it in
   Varnish
6. Make both /grace/test.cgi and /nograce/test.cgi rewrite to
