statsrv.go a simple static http server to serve your stats.json (or any file really)

statsrv.go

/*
statsrv is a very simple static file server in go using the defaul net/http package

Usage:
	-p 8080               port to serve on
	-d /var/tmp/stats     the directory of static files to host

Go to http://localhost:8080 - it will display the index.html or directory listing file.

Place any .json file and it will be served as application/json type document. :)

Example:

mkdir -p /var/tmp/stats
echo '[{"type": "apache", "stats": [{"requests": 123212}, {"200": 123200}, {"4xx": 11}, {"5xx": 1}]}]' > /var/tmp/stats/stats.json
go run statsrv.go
curl -v http://localhost:8080/stats.json

*****************
Caution:  Currently no logging or any other safeguards, so suggest to never use this on a public accessible server !!
