Hi, I need some help.
I'm using ktor server to build a REST server.
I'm using jackson ContentNegotiation and everything is fine.
Except now I want that some of my routes answer sometime an image.
But event I'm setting the ContentType in my response (call.respondBytes(resultFile.readBytes(), ContentType("image", "png"))) I see that actual headers are still "application/json" ...
How can I tweak ktor to not override contentType when I'm explicitly setting it in my response ?

did you try Route.static()?

[Jorge R]

this is how im serving images

[jfburdet]

The images i'm serving are dynamicaly fetched or buid internaly, so they are not static assets.

Hmm, that's weird, it seems that I misinterpreted the problem.

The cause of my problem could be the following : answering http 304 with json auto-negotiation can lead to something weird :

call.respond(HttpStatusCode.NotModified, message = "") will make a correct 304 response.

BUT

call.respond(HttpStatusCode.NotModified) will return a json document containing "304" !!!
