created issue #1

Jul 9, 2010 09:07AM

After analysing my site with Google Page Speed (

http://code.google.com/speed/page-speed/), the extension informed me that caching would be optimised if static files were served with the "Vary: Accept-Encoding" header (

http://code.google.com/speed/page-speed/docs/caching.html#LeverageProxyCaching).

Allowing users to set this via app.yml or, preferably, setting it by default would, I understand, allow ISPs and other proxies to better cache static CSS and JS files.

Marked as fixed.

Note that now App Engine add Vary: Accept-Encoding header when response is gzipped.

Marking the issue as Fixed.

Not sure if it really fixed.

Take a look at the following page speed report, it still complains that some compressible resources don't have the header:

(

www.mobizy.com is hosted on appengine)

Can you share your app.yaml file ?

Thanks in advance.

It's a Java app - could that be the issue, could it be only fixed for Python apps?

The appengine-web.xml is attached, thanks.

Is there an ETA for when this will be fixed? It seems like it would be an easy win...

Please consider allowing additional headers to be configured for static files. Our apps would benefit if headers for P3P and Cache-Control were set, as http-equiv meta tags do not provide a reliable alternative for these headers.

#12 can you fill a separate feature request?

Thanks in advance.

The following publicly cacheable, compressible resources should have a "Vary: Accept-Encoding" header:

PageSpeed complains please fix

The fix for

issue 3104

allows static file headers to be set in appconfig from version 1.7.0. As a Python app.yaml example:

- url: /images
static_dir: static/images
http_headers:
Vary: Accept-Encoding

I'd still prefer this header be set by default, however, since it's an automatic win for every application currently deployed.
