I am wondering if anyone has an simple answer to this. If you hit an Akamai server for an image, but the response is returned with a 304 code instead of a 200, does Akamai charge for the call since no data is returned with a 304 and image is served from the browser cache?

A:
If by charge you mean count against your monthly bandwidth allotment, then no. Assuming you're using their Origin Pull service, the only exception is if the file is in your cache but not stored on Akamai's edge servers. In that case, Akamai pulls the file from your server which would incur a small bandwidth hit as both incoming and outgoing traffic is counted on Akamai.
