New visitors to your web site will make several HTTP requests to download all your web site files. By add Far Future Expires header, you make those files cacheable. This avoids unnecessary HTTP requests on subsequent page views. Expires headers should be used on all components including scripts, stylesheets, and Flash components.
If you have access to httpd.conf, you can add
[FilesMatch "\.(ico|pdf|flv|jpg|jpeg|png|gif|js|css|swf)$"]
Header set Expires “Thu, 15 Apr 2010 20:00:00 GMT”
[/FilesMatch]
* Replace [ with < and ] with >
You can also add the above code if you can only access .htaccess.
Remember to change the date when it expired.
Your web site Yslow performance grade should improve.

Entity tags (ETags) are a mechanism to check for a newer version of a cached file. Removing the ETag reduces the size of the HTTP headers in both the response and subsequent requests.
If you have access to httpd.conf, you can add
FileETag None
Or if you can only access .htaccess only, you can add
Header unset ETag
FileETag None
Your web site Yslow performance grade should improve.

WP-Cache Plugin is one of the top 10 plugin for WordPress Blog. Basically, it speeds up your site and if your blog has high traffic, it is recommended that you have it installed. Remember to delete cache if you edit your wordpress theme.
WP-Cache is an extremely efficient WordPress page caching system to make you site much faster and responsive. It works by caching Worpress pages and storing them in a static file for serving future requests directly from the file rather than loading and compiling the whole PHP code and the building the page from the database. WP-Cache allows to serve hundred of times more pages per second, and to reduce the response time from several tenths of seconds to less than a millisecond.
WP-Cache started from the ”’Staticize Reloaded”’ by matt and billzeller. Most of their recommendations also apply to WP-Cache. Current version, WP-Cache2, is a huge improvement over previous versions of WP-Cache.
WP-Cache is composed of two parts:
- Two-phases Wordpress hooks. The first is called at the very begining –wp-cache-phase1.php– when just few code has been compiled. The second –wp-cache-phase2.php– after all plugins have been executed. The first phase checks if the requested URL is already cached, if so it serves from the static file and finishes. The second phase stores the generated page in a static file for further request.
- The WP-Cache plugin. This plugin configures and manages the whole process. It is easy to use and self-documented. It allows yoy to enable or disable cache, define expiration time for static pages, define rules for rejecting and accepting which URLs and php files can be cached, and shows and delete pages in cache.
Current version is 2.1.2 updated on 2007-09-21
