I’ve been working to speed up my site over the past few days. When running Yslow! on my Mint-enabled blog, it states that the Mint javascript files (which can’t be served from the CDN because when I try to do so, Mint stops recording visits) have a Expires Header set to a date in the past (1997/07/26).
I’ve done a screenshot of the relevant section of the Yslow! results page which shows the issue.
What I understand this to mean is that client browsers are told to load the script every time they access any one of the blog’s pages, regardless of the number of times they’ve accessed the javascript file already.
Is this correct? And if so, is there a reason for it?
