I am living in the Delhi, where there is considerable censorship of the web. My own material is not 'adult'. I use blogger to publish the index.html homepage to my own domain. The rest of the site is 'conventional'.
If I navigate to http://www.classicwebsites.org , I always see a cached page, maybe 5 or 6 days old. It is not cached on my pc, as it comes back after I clear the cache and try again. Also, that's the page I'll see from any pc in the area.
But if I navigate to http://www.classicwebsites.org/index.htm, I will get the new page every time, even minutes after posting it. This is fine for me, but presumably other readers will always be seeing the old cached version.
