That will send the content to the server for unpacking. A slightly more convoluted option might be to put the zip in the anchor part instead and have the response serve code to unpack it from there client side. Though now the server can't scan for damaging content being sent via it, even if it wanted to, as the anchor part does not get sent to the server.

I thought the same thing (though you could do it without anchors as long as the static content server used a glob for routing all traffic to the same web page). It would really simplify hosting.
