I only see one POST in that log.. but I suspect there was one some time
before this (the Referer header of the first request seems to imply
this..). A study of the traffic with ngrep is probably recommended here,
starting by studying the traffic to/from the client, and if that does
not indicate what is going on (i.e. if everything looks alright there)
also studying the traffic to/from the web server.

I however see many redundant requests for jwiki.jpg, probably because
your Fnord/1.7 server is not sending a Date header which makes sending a
Last-Modified somewhat pointless (no point of reference), or maybe the
server is giving an incorrect Content-Length thereby preventing
jwiki.jpg from being cached.
