Since static files are only updated when you push new releases, you
can add a version number into the url for the static resource.
E.g. (python/django), in app.yaml:
- url: /__v[^\/]+/static
static_dir: yourapp/static
expiration: 365d
Then in your template, create a templatetag (or something) that
injects the current build number into the url:
<img src='{% vurl "/static/images/myimage.jpg" %}'/>
The rendered output would look something like:
<img src='/__v12345/static/images/myimage.jpg'/>
where 12345 is your build number.
Doing this will allow you to set very long timeouts, but still have
fresh content (e.g., on a new code push).
