I have a problem with paths.
I want to make a redirect from /path to ‘/path/’ because the HTML returned by ‘/path/’ has some relative paths for images, css, …
But when I declare theses 2 paths in routing, ktor seems to make no difference between them.

[orangy]

trailing slash is ignored by routing, but that’s a compelling reason to stop doing so…

[gaetan]

yes… but browsers make difference between URL with trailing slash and without. Ktor should also, no?

[orangy]

I think yes, but not very clear how exactly

[gaetan]

Just /path and /path/ should be considered as distinct.

On https://github.com/ktorio/ktor/blob/8f4f43a0b0281b213f0be1df1b5fa8b160ae1e5c/ktor-server/ktor-server-core/src/io/ktor/routing/RoutingPath.kt#L10

the filtering it.isNotEmpty() removes the last empty segments that appears in case of trailing slash.

[orangy]

Not only that.

[orangy]

routing {
   route("foo") {
      route("bar") {
         // what here to make a distinction?
      }
   }
}

Ok, I understand the problem. Will think about it.

[gaetan]

We have to find a solution because it’s a pity to add a proxy server to manage this kind of redirection.

[orangy]

Absolutely. For now you can workaround by looking at the original path

[orangy]

if (!call.request.path().endsWith('/')) return@get call.respondRedirect("…")

[gaetan]

I don’t understand where this code would go.

[gaetan]

That is the code I wanted to use (and not working)

routing {
            get("/") { call.respond(call.resolveResource("index.html")!!) }
            get("/federerInData")   { call.respondRedirect("/federerInData/", permanent = true) }
            get("/federerInData/")  { call.respond(call.resolveResource("/federerInData/index.html")!!) }

[orangy]

instead of two routes for federerInData, use one (either) and put that code at top
