Summary

Client-side web site optimization can take you only so far. To fully optimize high-traffic pages, you've got to turn to the server-side. By configuring your server to accommodate conditional SSI and browser sniffing, abbreviated URLs, and shunting defaults to the server, you can dramatically speed up your pages. Here is a list of key points in this chapter:

  • Use SSI to minimize HTTP requests on high-traffic pages.

  • Where possible, pre-merge dynamic content without SSI for maximum speed.

  • Use server-side browser sniffing to minimize HTTP requests, especially for JavaScript files. Use the fastest technology available (JSP > PHP > XSSI).

  • Conditionally include meta tags.

  • Abbreviate your links, manually or automatically, with mod_rewrite and shorturls.pl (20 to 28 percent savings).

  • Optimize your forms and CGI scripts to shunt defaults to the server.

  • Use mod_perl to speed up Perl scripts.

  • Don't require www . for your domains.
