As an alternative, you can set a header which will specify a cache-bypass to all intermediate caching services. When you send your HTTP request, include the following headers: Cache-Control: no-cache Pragma: no-cache' On Sat, Nov 2, 2013 at 3:48 PM, <philip.gladst...@gmail.com> wrote: > I also wrote another endpoint in my app that does a fetch call to any > site, and it appears that I can get to any site apart from my server.

What you could try to do is open up a Compute Engine machine (which shares the same networks as App Engine machines), and traceroute the connection from Google servers to your server. As another alternative: since you can get to any site except for your current server, can you move this server onto a Compute Engine machine? The fetches will speed up considerably, since they'll be done over the Google internal network and not over the open Internet. ----------------- -Vinny P Technology & Media Advisor Chicago, IL App Engine Code Samples: http://www.learntogoogleit.com -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
