Re: Uncacheable .cache.js files ?

ok your right - putting the url into new tab seems to work as expected.

however i wasn't expected to see the mixed cache and uncached variantes when pressing F5, CTRL+R or clicking reload while the devtools are open (i did uncheck Disable cache (while DevTools is open) in chrome settings):

Pro Tip: don't use "refresh" to test caching in Chrome, particularly when Development Tools are open.

When I refreshed Google Groups, the request for the cache.js had a "Cache-Control: max-age=0" header. When copy/pasting the URL to another tab (with Dev Tools open), the file is served from cache.

Hi,

While analyzing a cache problem, of my own app, i came across a strange issue that i cannot explain. Good thing is, that we have showcase to reproduce the issue (so i think) - google groups itself.

lets take a look into google groups, which is using GWT AFAIK, and see what it request and what it caches. Looking for the first <md5>.cache.js file ( in my case https://groups.google.com/forum/1CC2C4879D0404FA63089F39885AF88D.cache.js at the time of writing for Chrome) shows valid caching headers of one year the response. pressing reload shows that the browser always does a fresh request for <MD5>.cache.js where it could and should use the cached variant from the previous request.

Strange thing is that caching works with the deferred js-variants: https://groups.google.com/forum/deferredjs/1CC2C4879D0404FA63089F39885AF88D/13.cache.js in my test.

Can anybody explain this?

Thanks,
