Just-In-Time google app engine blobstore upload url

[NightStalker via StackOverflow]

I am busy with a Python GAE site. All has been going ok until now. I am using CKEditor as my editor. And it supports image upload and browser url functionality. The problem is the blobsture upload URL expires after first upload and then no longer works until the page is reloaded.

After a lot of googling around, I found some solutions to get the url with jquery before doing the upload, but I cannot do this within CKEditor. So I wanted to do a Just-In-Time upload url as described in this google group: https://groups.google.com/forum/#!topic/google-appengine-python/G36NAm50CY4

But the url posted to the example is no longer working and I am not sure how I would go about this, as I am still quite new to Python and GAE.

Any ideas?

Thanks
