A question for ktor/thymeleaf integration. Is there a relatively straightforward way to enable building composable applications (e.g. I have foo and bar that can run as their own applications, but I might want to compose them and mount either at /foo/ and /bar/ such that context-relative URLs work? More broadly, is there a way to have context-relative URLs work properly using embedded Netty (and not Tomcat) at all?

It seems like it is potentially possible with some StandardLinkBuilder.computeContextPath shenanigans, but it seems like it would be nicer/more elegant to actually provide an IContext implementation (or adapt the existing servlet one..?)

Essentially what I’d like is that if I have @{/location} in a template defined in foo, then when running a standalone application in foo, it resolved to /location but when `foo`’s routes are mounted inside another application baz it resolves to /foo/location , or something like that.

The Thymeleaf plugin can only be configured once, so perhaps this is just something that needs to be handled with `computeContextPath`…

Can you please file an issue or describe your use case in KTOR-1469 if this feature request seems relevant to you?

[Dylan Lukes]

I’m working on a proof of concept implementation of IWebExchange and concomitant interfaces (IWebApplication, IWebRequest, IWebPrincipal etc) to see if it’s doable and if so I’ll publish it.

[Dylan Lukes]

The main hairy bits currently are mapping Ktor’s sessions to IWebSession and gracefully handling getting resources when not in a servlet context.

[Dylan Lukes]

Otherwise, pretty straightforward.

It should be possible to get Thymeleaf to happily behave almost like it’s in a servlet where the context path is Application.rootPath (which is what gets set when we are in a servlet context to the context path anyhow).

I’ll reply to KTOR-1469 once I have something working 🙂.
