App.yaml designed for serving a static site on Google App Engine (Python). Copy your static html and files into a folder called "static" next to app.yaml. Contains a bunch of mimetype declarations from html5boilerplate's .htaccess. May not be necessary for most situations.
my_site
app.yaml
static
index.html
...
The static folder is invisible when serving (i.e. my_site/static/index.html is accessed as http://your-app-name-here.appspot.com/index.html.
Remember: No spaces in file or path names. Case sensitive.
@SoulAuctioneer I found that adding each mime type allowed by backend api hosted in the same space to function You're blanket .* block would prevent my api from working.
I actually found this document very very helpful in getting my static files as well as my backend Google api working at the same time.
