Attached patch(SLING-2707.patch) with feature details at https://cwiki.apache.org/confluence/display/SLING/Chunked+File+Upload+Support
Salient features:
1. Extension to [SlingPostServlet|http://sling.apache.org/site/manipulating-content-the-slingpostservlet-servletspost.html]
2. Chunk upload is supported in "modify"operation of [SlingPostServlet|http://sling.apache.org/site/manipulating-content-the-slingpostservlet-servletspost.html] ( ie. In default operation) . No new operation introduced for it.
3. Chunks are stored within actual path in mixin node type. Defined [sling:chunk] and [sling:chunks] for this purpose.
4. Added six integration test cases validating different scenarios.

> Use cases: 
> 1. Large file upload - With high speed internet connections, advent of cloud and HD going mainstream, Sling should support large files (> 2GB) upload.
> 2. Fault tolerant uploads - Sling should provide capability to resume upload from failure point. It should not require client to restart the complete upload process. 
> 3. Faster upload: Sling should support its clients to initiate multiple connection and upload file chunks in parallel.
