>> This prompts your visitor to keep hitting refresh in annoyance because they can briefly 'see' the info they want, before it goes to the blank page.

This IE 6.0 user must have been pretty anxious to see one particular page. They reloaded the page over 8000 times throughout the entire night (in their timezone).

Look at this:
200.90.#*$!.#*$! - - [04/May/2011:10:33:35 -0500] "GET #*$!XX.html HTTP/1.1" 200 4239 "http://www.google.com/search?hl=pt-BR&source=hp&q=#*$!XX" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.04506.648; .NET CLR 3.5.21022)"
200.90.#*$!.#*$! - - [04/May/2011:10:33:45 -0500] "GET #*$!XX.html?fb_xd_fragment HTTP/1.1" 200 4220 "http://www.facebook.com/plugins/like.php?channel_url=#*$!XX%3Ffb_xd_fragment%23%3F%3D%26cb%3Df3d143e5c17a0d%26relation%3Dparent.parent%26transport%3Dfragment&font=trebuchet%20ms&href=#*$!XX&layout=box_count&locale=en_US&node_type=1&sdk=joey&send=false&show_faces=false&width=55" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.04506.648; .NET CLR 3.5.21022)"
(details are blanked out)

and it went on all night long until I noticed in the morning and I blocked it.
