h1. Implementation
h3. Extension to [SlingPostServlet|http://sling.apache.org/site/manipulating-content-the-slingpostservlet-servletspost.html]
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
h3. Chunks Storage
Chunks are saved in temporary location identified by upload id in the following node structure.

h3. Chunk processing
* First/Intermediate chunks: Chunk is saved in temporary location in jcr. Ignores all upload semantics (@TypeHint, etc) and request parameters.
* Last chunk: Stitches all chunks. Process all upload semantics and request parameters and creates jcr node structure at the right location.
