Re: Help with idenitifying problems bluehost analyzed
Hi Gary, Backlight sets various headers, including those for caching. All of those files you've listed are directly accessed via the web server as static files, and not passed back through Backlight in any way. The solution then is a matter for server configuration.
I'll run the same test on my own Bluehost installation, and see what steps I can take through cPanel or .htaccess directives to improve the score.
Can you email me the full list of files, so that I can see whether any of the URLs are handled by Backlight rather than static files?

You can set this via .htaccess. Search "expires headers" on this page for info:

Re: Help with idenitifying problems bluehost analyzed
I've had a look at my homepage, a full-sized Theater album. The score was 94%.
After having a look at http://garylittle.com/galleries/flora-a … /flowers1/ in Google Chrome, I've found that the browser is caching the content, despite a lack of an Expires header. On first load, the total downloads totalled 2.2MB. On refresh, this had reduced to 17.9KB. That raises the question: what is the concern here with caching? Is it that the files may not cached, causing a performance penalty, or that they are being cached when they shouldn't necessarily be, possibly causing stale files to be shown?
Managing caching well is difficult, and I'm by no means an expert on it. Backlight aims for the middle ground of efficiency and returning the latest files. Essentially, what this does is tells the browser to cache a file, but to check that the file is current on each page load. This check is responded to by the server as either a very lightweight response stating that the cached version is good to use, or a heavier response, with the latest version of the file. We can do that in Backlight, because the back-end is an application that can apply logic to the request and contents of the file to be returned.
As far as I know, setting the Expires header alone will tell the either one or both of these: 1. That there is no need to check for a newer file until a set period has passed, and 2. That the browser should check for a newer file after a set period has passed.
While I'm happy with what Backlight is doing, I need to read up more on what the Expires header alone really means. A quick glance suggests this page provides some decent information on caching in general: https://developers.google.com/web/funda … hing?hl=en

Re: Help with idenitifying problems bluehost analyzed
This is great Ben, I really apprediate your thinking on this. While not anywhere4s near your expertise, I know that getting a file by going to the root and parsing down, would definitely slow things up. Let me know if you need anything else from
Bluehost, a truly great help desk people.
