Is there a way I can override the Content-Type header in

ApplicationCall#respondFile

? It seems like using

wrapHeaders

in the

configure

block doesn't have access to the headers that are later appended, and Ktor uses an unsatisfactory way of getting the content type for me (using the file extension). I assume I would be able to emulate

respondFile

if all else fails, but that would likely mean having to handle partial gets as well and so I'd like to avoid it if possible. I'm currently getting a result like this when appending the Content-Type manually.

The easiest way is to use the

LocalFileContent

class directly:

routing {
    get {
        call.respond(LocalFileContent(File("file.jpg"), contentType = ContentType.Text.Plain))
    }
}
