BlobStore - Upload Servlet and User Session Variables

[savilak]

I use BlobStore to store excel files as per Ikai's sample 

(http://ikaisays.com/2010/09/08/gwt-blobstore-the-new-high-performance-image-serving-api-and-cute-dogs-on-office-chairs/#comment-530).

I use facebook to authenticate my users and I keep the user name at a session variable.

The blobstore upload servlet creates a new session and the user name is not accessible any more (why is this happening?).

Ikai on his sample uses UserServiceFactory, which works only with Google Users authentication (is this correct?).  

How can I overcome this issue?

I would much appreciate some feedback on the issue.

Solved the issue! 

This was caused localy only be because the request used not 127.0.0.1 but the name of my machine thus was creating a new session!
