so far using coral CDN is working great! my bandwidth usage has dropped dramatically.

by the way, to send the appropriate header from lighttpd so as to trigger the fallback over-quota behaviour, just add this line to lighttpd.conf:
setenv.add-response-header = ( "X-Coral-Control" => "redirect-home" )

also, i am apparently now one of the major users of coral.

i'm trying out the coral content distribution network as a way of reducing the amount of bandwidth i use by hosting pets. we'll see how it works out… i just worry in general about relying on stuff outside of my immediate control–what if the response time is slow? or if i hit their bandwidth limits? on the other hand, their new over-quota system means that if i do use too much of their bandwidth, requests will just get redirected back to my server, so in theory the pets should never become unavailable.

anyway, it's certainly worth trying, and easily reversed if it doesn't work out.

EDIT: hmmm it looks like the new over-quota behaviour only kicks in if you serve an additional header in your HTTP responses. i'll have to see how to do this in lighttpd (which is what is serving up the pet's SWF files).
