Drakaalfirst.appspot.com is the MS version of the HR xyhdtv.appspot.com  They are code identical.

 

It appears that DrakaalFirst gets cache hits,

 

 

But xyhdtv doesn’t.

 

 

 

 

The Static traffic I know why is happening, I hard coded some links to drakaalfirst that don’t get linked to in xyhdtv.

 

Is this by design?

Even Static files with the app.yaml set to have caching don’t on HR deployments.

It’s not so much that I can’t get caching from Google, but that the way this is set even a user bouncing between pages will re-download the CSS elements and Images, which is highly inefficient.

 

Any one from Goog want to weigh in on if this is by design? Or if it will be resolved?  Probst’s site averages 3.5 Page Views Per user so I’m using 2.5x as much bandwidth as I should… I won’t go broke on this, but it would be nice to have the site load faster for Dial-up users visiting their second and third pages.

Oh, and for reference here are the headers for the same file on static on MS.

Do you have billing enabled on both?

Are you setting that cookie?

It's quite possibly responsible for disabling the caching
