Add support for http byte-range requests [SPR-10805]

[spring-projects-issues]

Nicolas Pottrain opened SPR-10805 and commented

Is it possible to add support for byte-range requests in the mvc:resources ResourceHttpRequestHandler.
This will enable the serving of video files to iOS devices and for Safari on Mac.

This post seems related, I haven't tried it though: http://datum-bits.blogspot.fr/2013/01/implementing-http-byte-range-requests_30.html

Are you running on Tomcat? It looks like the DefaultServlet there supports byte-range requests. In which case it might be simply be a matter of enabling default service handling in your Spring MVC config. When the ResourceHttpRequestHandler can't find a resource it forwarded to the container's "default" servlet.

More generally speaking the ResourceHttpRequestHandler was designed for serving application resources (css, js, images, etc) and is not optimized for serving large files (like videos) which is what byte-ranges would be most attractive. So if we added such support it would almost have to along with more optimal IO (e.g. file mapped byte buffer) to support the use case fully.

This is now available in the master branch (4.2.0.BUILD-SNAPSHOT). Nicolas Pottrain it would be very good if you could verify it works for you. Thanks!

I have some issues in Chrome after this feature was added. Is it any way to manually disable it?

We ended up adding a servlet filter that drops attempts to set ACCEPT_RANGE header.

Sample bootapp showing this issue is at https://github.com/krm1312/springrangeissues. Take that project and:

mvn clean package && java -jar bootapp/target/bootapp.jar

and then try a range request with curl:

curl -vvv -H "Accept-Encoding: gzip"  -H 'Range: bytes=4726785-5726784' http://localhost:8080/test/file.bin > /tmp/f

It effectively hangs.

If anybody else runs into this issue...

Just removing Accept-Range didn't work. RFC says browsers may send a range request anyway. Now we're setting Accept-Range: none in the filter and hiding any incoming Range header (by wrapping the request and overriding getHeader). Basically, try to tell the browser we don't support range requests and even if the browser sends a range request, ignore it and serve up a 200 with full content.

Andrei Holub, would you mind creating a new ticket to describe the issue with Chrome you're running into? We can add a way to disable it but would like to get some more details.

Kevin McLaughlin, it sounds like your issue is with actually trying to use byte ranges without success? Would you mind also creating a new ticket? We'll take a look.

This ticket is for the original request and is already closed and will not be re-opened.

Thanks!

Andrei and I are colleagues, so, describing the same incident/app. Will open two new tickets though - one to allow disabling and one to investigate/fix the issue when enabled.
