Cache Static	Applicable Objects	Any non-html object with a mime type of "text/", "javascript" or "image/" that does not explicitly have an Expires header of 0 or -1, a cache-control header of "private", "no-store" or "no-cache" or a pragma header of "no-cache"
Cache Static	What is checked	An "Expires" header is present (and is not 0 or -1) or a "cache-control: max-age" directive is present and set for an hour or greater. If the expiration is set for less than 30 days you will get a warning (only applies to max-age currently).
Use A CDN	Applicable Objects	All static non-html content (css, js and images)
Use A CDN	What is checked	Checked to see if it is served from a host with "cdn." or ".yimg." domain or if it is being sent as HTTP 1.0 with keep-alive headers (a common Akamai configuration)
Combine CSS/JS	Applicable Objects	All css and javascript objects
Combine CSS/JS	What is checked	If multiple files of the same type are served from the same domain then all of those files fail (i.e. multiple css files served from o.aolcdn.com)
GZIP Text	Applicable Objects	All objects with a mime type of "text/" or "javascript*"
GZIP Text	What is checked	transfer-encoding is checked to see if it is gzip
Compress Images	Applicable Objects	Any object with a mime type of "image/*"
Compress Images	What is checked	GIF - All pass PNG - Must be 8 bit or lower (no 24-bit PNGs will pass) JPEG - Within 10% of a photoshop quality 50 will pass, up to 50% larger will warn and anything larger than that will fail.
Keep-Alive	Applicable Objects	All objects that are from a domain that serves more than one object for the page (i.e. if only a single object is served from a given domain it will not be checked)
Keep-Alive	What is checked	The response header contains a "keep-alive" directive or the same socket was used for more than one object from the given host
Cookies	Applicable Objects	All requests
Cookies	What is checked	All responses are checked to make sure cookies are not written to the aol.com domain
Minify JS/HTML	Applicable Objects	All html, javascript and json responses
Minify JS/HTML	What is checked	HTML will be run through tidy and script will be run through jsmin. If the original content was gzip encoded, the minified version will also be gzipped for comparison. If > 5KB or 10% is saved then it will fail. If > 1KB is saved, it will warn, otherwise it will pass.
