Re: [jersey-dev] Range request implementation

[Zoltan Farkas <zolyfarkas@xxxxxxxxx>]

When I looked into this a while ago, I did not find one.

Here is how I ended up implementing it:

https://github.com/zolyfarkas/spf4j-jaxrs/blob/master/spf4j-jaxrs-server/src/main/java/org/spf4j/jaxrs/server/resources/FilesResource.java#L84

hope it helps.

Hi,

I'm looking to implement range requests with Jersey 2.x:
https://developer.mozilla.org/en-US/docs/Web/HTTP/Range_requests

Is there a "canonical" implementation of this?

From looking at a few sources
https://colamda.de/blog/2016-07-08-files-with-jax-rs/
https://github.com/heruan/jaxrs-range-filter
I gather that the implementation involves:
* a ContainerResponseFilter (or possibly WriterInterceptor?) that
parses the Range header
* a subclass of StreamingOutput that slices the entity bytes according
to the range

Does that sound reasonable? I'd very much reuse a time-tested library however.
