I don't use gin (I use chi) but from the docs it seems gin is based on httprouter, and thus maybe this pattern/example is useful? https://github.com/julienschmidt/httprouter#multi-domain--sub-domains (looks very similar to yours, though - only difference is that this example uses the fully-qualified hostname instead of just the first part)
Chi provides a middleware for doing this: https://github.com/go-chi/hostrouter - the source code might help you with what you're doing? https://github.com/go-chi/hostrouter/blob/master/hostrouter.go On Fri, Oct 27, 2017 at 3:44 AM, Swati Sharma <swatin...@gmail.com> wrote: > Hello > I am working on a project where I need to setup the multiple sub-domains > with the routes.
