It's not a Go issue. The browser is requesting favicon.ico and that's also handled by the default handler. Just learned my lesson so ;). |

What version of Go are you using (
go version)?go version go1.9.2 windows/amd64 (where I analyzed and tested the problem)
go version go1.9.1 linux/amd64 (where I first detected the problem)
Does this issue reproduce with the latest release?
yes
What operating system and processor architecture are you using (
go env)?windows / amd64
What did you do?
Changed the port # from 8080 to 80 in the following example.
https://play.golang.org/p/96H7CauyUM
What did you expect to see?
Independent of the port number I expected the count to be increased by one per request.
What did you see instead?
While the count is increased by one per request using port 8080 it is increased twice per request using port 80. It looks like the handler function is being called twice.
