The 10 minute limit is in part a measure to prevent against DOS attacks to the upload url that is generated.
The scenario you have described is usually handled by using some javascript to create the upload URL on demand when the user is ready to submit the form. Work is being undertaken to provide a more descriptive error rather than just redirecting to the temporary blobstore error URL. You could probably star http://code.google.com/p/googleappengine/issues/detail?id=6313 if being able to redirect to a specific URL on upload failures as well. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
