I am testing the home page of my website. I have uploaded all the used images to Amazon S3 using Bucket Explorer & set Expires header for that image folder.
Waterfall model of first view giving correct model then it prompt at top that “Test is partially complete.
This page will refresh every 30 seconds until the full test is complete.” Then repeat view shown after 30 second. All the images returned 304 response. But I have set expire header to all the images then they are cached in first load. Then why it return 304 error code in repeat view?
Thanks for help.
