A first-time visit to a page may require several HTTP requests to load all the components. By using Expires headers these components become cacheable, which avoids unnecessary HTTP requests on subsequent page views. Expires headers are most often associated with images, but they can and should be used on all page components including scripts, style sheets, and Flash.");YSLOW.doc.addRuleInfo("ycompress","Compress components with gzip","Compression reduces response times by reducing the size of the HTTP response.

These frequent evaluations degrade the user experience.");YSLOW.doc.addRuleInfo("yexternal","Make JavaScript and CSS external","Using external JavaScript and CSS files generally produces faster pages because the files are cached by the browser. JavaScript and CSS that are inlined in HTML documents get downloaded each time the HTML document is requested. This reduces the number of HTTP requests but increases the HTML document size. On the other hand, if the JavaScript and CSS are in external files cached by the browser, the HTML document size is reduced without increasing the number of HTTP requests.");YSLOW.doc.addRuleInfo("ydns","Reduce DNS lookups","The Domain Name System (DNS) maps hostnames to IP addresses, just like phonebooks map people's names to their phone numbers.

The browser cannot download anything from the host until the lookup completes.");YSLOW.doc.addRuleInfo("yminify","Minify JavaScript and CSS","Minification removes unnecessary characters from a file to reduce its size, thereby improving load times.

In IE, if an external script is included twice and is not cacheable, it generates two HTTP requests during page loading.
