GAE: Uploading to Blobstore Service kills the Session

So I'm using GAE and created a session to persist some data between some JSP and servlets. The problem is when I access the Blobstore Service to upload a file, the session is killed and the user is logged out.

This is the form attributes that causes the problem: action="<%= blobstoreService.createUploadUrl("/upload") %>" method="post" enctype="multipart/form-data"

If you use Eclipse for development, you can validate each of your jsps prior to deploying. If you clear all errors first, the compile errors will go away. I have been surprised at the errors the dev environment did not complain about, but prevented deployment.

It seems that the session is being killed based on the blobstoreService.createUploadUrl("/test") changing the domain in the development environment. If i test using my dev machine IP address the session is destroyed as the call back URL results in computername:port/test rather than ipaddress:port/test. I f i use computername in the URL to submit the form originally the session remains and dev is happy.

For anyone looking at this in the future, it seems this issue only happens when working in the local development server but not after deploying the app.

I had an identical issue while testing on my local dev server. Uploading files to the GAE Blobstore logged the user out and messed up the session. After I deployed my app, everything worked perfectly online. Wish I had tried that first before spending hours trying to find out how to fix it.
