currently i’m piecing the URL together from the Session argument as follows, but it’d be nice if there were an exported public way to do this. or did i miss it?

```julia
App() do session::Session
       server = session.connection.connection.server
       DOM.div(string(server.protocol, server.url, ':', server.port, server.routes.table[1].first))
end

```

[EDIT: updated code to actually work]

What do you want to do exactly?  
There are multiple ways to get the servers public url.

i want to do exactly that-- programmatically get the servers public URL, so i can either display it on the page or better yet copy it to the clipboard on a button press. thx!

I guess you can use:

```julia
using Bonito

get_server(session::Session) = get_server(session.asset_server)
get_server(server::HTTPAssetServer) = server.server
get_server(server::Bonito.ChildAssetServer) = get_server(server.parent)
get_server(any) = error("Not an HTTP server for session")

App() do session::Session
    server = get_server(session)
    DOM.div(string(Bonito.online_url(server, "")))
end

```

Would be cool if this works:

```julia
App() do session::Session
    DOM.div(Bonito.Link("/"))
end

```

This doesn’t work right now, but I think that could fall under the use cases for `Link`.

thanks! those new `get_server` definitions would be handy to have in Bonito. and i guess i misunderstood the docstring for `online_url`– i interpreted that as _setting_ the URL, not getting it.
