Re: [google-appengine] How do I use get_serving_url correctly?

Yes, you can cache the result. In practice, subsequent calls of get_serving_url on the same blob should be faster, but if you have more new blobs than old ones on a page it can be slow. The resulting URL only becomes invalid if the blob is deleted. On Tue, Aug 24, 2010 at 1:53 PM, Flips wrote: >
