What steps will reproduce the problem?
Why are requests with chunked transfer encoding not permitted in http/cgi? Is this
according to the cgi specification? Git sends data (push) with chunked transfer encoding
and I believe that it's supported in Apache.

Side-note: By disabling the error-check in ServeHTTP chunked requests seems work in
general but when sending large data, >= 1MB,  in combination with writing the
"Content-Type" header the request data seems to be corrupted. Any other
header, e.g. "_Content-Type" works however.

Which version are you using?  (run 'go version')
go version go1.1 darwin/amd64
