WCF Streaming and resume options

I have a scenario that I need to implement. Namely, my server needs to implement WCF that would accept large files (500MB - 1GB) and support resuming in case the connection drops for any reason. I was thinking of using WCF streaming for this, but I was wondering if resuming is somehow supported out of the box or do I need to implement custom handling for this. What is the best course of action for in my case? Links to examples would be appreciated.

Upload and download methods should accept a parameter that controls the position of download/upload.

I am not sure this is implemented/supported out of the box. The WCF service must have a compatible client for this kind of approach.
