Hi Francois, As Nicolas said in this post: https://groups.google.com/forum/#!topic/google-appengine/k3LrZodr-WA the caching seems to be working correctly. I can see the proper Cache-Control and Pragma headers in the response when I use Chrome's Developer Tools screen. Are you still experiencing errors?
If you're still seeing errors on your end, try this tool: http://www.hurl.it/?url=http://dev.pronocities.com/theme/com.pronocities.theme.base/858/logo_mail.png(Press the Launch Request button when the page loads). You'll be able to see the response headers that Hurl.it gets back from the request. ----------------- -Vinny P Technology & Media Advisor Chicago, IL App Engine Code Samples: http://www.learntogoogleit.com On Sat, Jan 25, 2014 at 11:26 AM, Francois Masurel <f.masu...@gmail.com>wrote: > Hi everybody, > > Do you know why cache headers are modified by Google Frontend servers? > > Google prohibits my dynamically served static resources to be cached on > proxy and user sides. > > For example, Google set the Expires header to this: > Expires: Fri, 01 Jan 1990 00:00:00 GMT > > And Pragma and Cache-Control to this: > Pragma: no-cache > Cache-Control: no-cache, must-revalidate > > In my code, both Pragma and Cache-Control are set to public (plus max-age > for Cache-Control). > > Example of problematic resource: > > http://dev.pronocities.com/theme/com.pronocities.theme.base/858/logo_mail.png > > What is strange is that the same exact code works perfectly fine in other > apps like this one: > http://www.vinocities.com/theme/com.vinocities.theme.base/858/logo_mail.png > > Anybody knows what's going on?
