Thanks for your advices. I'll use the datastore and the blobstore.
When I first write my app, I supposed my static field will probably be drop by GAE, because of the non-use of API like memcache or datastore. I try it, for fun and curiosity. It was interesting to understand WHY it was a bad idea to do this. Thanks again for your answear, and have a nice day. 2010/10/27 Simon <[email protected]> > Yoyo, you are aware that you only have to enable your account as > billable and that it doesn't actually cost anything as long as you > stay within the free quota?
