TOC used FLAP to encapsulate its messages just as OSCAR does, however, FLAP has been hacked in such a way that it can be implemented on the same port as an HTTP server. By default, the TOC server operated in HTTP mode, indistinguishable from a typical web server. If a connecting client, in place of an HTTP request, writes the string "FLAPON" followed by two CRLFs, TOC would switch gears and start reading FLAP messages. Upon getting a user's profile, the client was expected to re-connect to TOC and use it as an HTTP server, which would host the user's profile in HTML.
