App Engine should not automatically cache anything unless you tell it to. Here are the probably cases:
1. Did you set cache-control headers? If you set cache-control:public, this may cause your ISP, any proxies, or even the App Engine infrastructure to hold on longer than you like. 2. Local browser cache? (Test using curl/wget/telnet) 3. Could your ISP be caching? I could be misunderstanding your email - are you using URLFetch? There may be some caching that happens on responses, but this data should be extremely short-lived. At any rate, you may want to ask this question in the Google App Engine groups: http://code.google.com/appengine/community.html On Tue, Aug 31, 2010 at 9:38 AM, Thomas Dvornik <[email protected]> wrote: > Hey guys, > > I'm building an application that processes xml, which can be located > on an external server.
