Send an HTTP 403 message to 40-bit browsers from 128-bit secure site?

[citpaj]

I have a secured site, which *requires* 128-bit cipher strength browsers. When a client with less than 128-bit cipher tries to connect, they get the standard browser error message instead of the HTTP 403 message. The server logs indicate that the web server tries to send the 403 message, but (I think) because a secured connection isn't yet established with the browser, the 403 message never reaches the client, and they get the default generic error page from their browser. I'd like to configure Apache to send a 403 message to the client -- does anyone know how I'd do that, given that my site requires 128-bit before a connection is established? Thanks.
