README.md

Go HTTP Server Example

A really, really simple HTTP server which accepts non-encrypted connections and returns only the last portion of the URI assuming it is the caller's name.

COMPILING

To compile this so that the resulting Docker image is valid you have to compile with a few flags set or you'll get some weird file not found errors.

CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo

Happy Hacking!
