Chrome not Caching JS / CSS

[Sumit Juyal]

 

I am working on a performance improvement of our website (https://now.tirehub.com) .  and this thing caught my attention when I was looking at Dynatrace “Real User Monitoring” . when I looked at waterfall chart of page load , I saw all the resources are getting loaded irrespective of browser Cache.

 

I was pretty sure something is wrong with our cache headers (feel free to click the link to see headers), but there was nothing wrong there . Then as usual I opened developer tool to see if browser is caching JS /CSS and figured that no matter what page I go to – JS and CSS are not getting cached by Chrome , although images and font files we cached.

 

Then I installed firefox and opened developer tool there. It indeed was caching JS / CSS as expected. Then I thought that it could  be chrome developer tool , but there are thousand of request recorded by  Dynatrace “Real User Monitoring” showing the same behavior.

 I am definitely missing something but don’t know what.

Many Thanks in Advance

Can you reproduce this without the Developer Tools open?

If not, then you may have checked "Disable cache" in the Network tab.

If you can reproduce this without the Developer Tools open as well, then this group is not the right one and you should use stackoverflow.com. If you end up discovering it is a Chrome issue, then you can use crbug.com for reporting it.
