If the filtering is based on IP address, that would make sense -
blocking an Akamai cache would cause a lot of collateral damage to
unrelated sites.

I believe the Chinese firewall also resets TCP connections if certain
keywords are detected, but maybe the word sex doesn't have a high enough
priority to get onto that particular blacklist. Try putting Falun Gong
on one of your pages and see if it still gets through. :-)

Or maybe Akamai delivers the data to its caches inside China in a
compressed or encrypted form, unintentionally circumventing the RST
filter as well as the IP filter?
