Re: [google-appengine] Static File Serving

[Nick Johnson (Google)]

Hi,

If you set an expiration time for your static content, it may be cached at geographically diverse endpoints. Without one, it won't be, as it doesn't know how long it's safe to cache for.

I am developing an application that targets the UK market and am
looking at ways of improving the download speed of static files hosted
on app engine such as .js, .css, .png etc.

My testing suggests that app engine is serving all static content from
america which adds significant latency. Downloading a static file of
size <1KB takes 200-250ms from england.

Are there any plans in the future to geographically distribute static
content across data centers? Or would I be better off using amazon
cloud front for serving everything static?

Don't understand what you mean by "appengine-web.xml" file.
But what Mr. Nick Johnson is suggesting I believe is to set an
expiration time for your static content as described here:

http://code.google.com/appengine/docs/python/config/appconfig.html
i.e use a default expiration or expiration declaration in your Yaml
file.

I don't see all this as a potential bug.

See:
http://code.google.com/appengine/docs/java/config/appconfig.html

(notice the 'java' in the url :)

stumpy is saying already setting a expiration time, just that it has
no affect on edge caching.
