How to Update a resource with a large attachment with PUT request in JAX-RS?

Question

I have a large byte file (log file) that I want to upload to server using PUT request. The reason I choose PUT is simply because I can use it to create a new resource or update an existing resource.

My problem is how to handle situation when server or Network disruption happens during PUT request. That is say I have a huge file, during the transfer of which, Network failure happens. When the network resumes, I dont want to start the entire upload. How would I handle this? I am using JAX-RS API with RESTeasy implementation.

Some people are using the Content-Range Header to achieve this but many people (like Mark Nottingham) state that this is not legal for requests. Please read the comments to this answer .

Besides there is no support from JAX-RS for this scenario.

If you really have the repeating problem of broken PUT requests I would simply let the client slice the files:

PUT /logs/{id}/1
PUT /logs/{id}/2
PUT /logs/{id}/3

GET /logs/{id} would then return the aggregation of all successful submitted slices.
