  == Description ==
10
- A modification of WP-Cache that produces static html files. After a html file
11
- is generated your webserver will serve that file instead of processing the
12
- comparatively heavier and more expensive WordPress PHP scripts.
13
 
14
- However, because a user's details are displayed in the comment form after
15
- they leave a comment, the plugin will only serve static html files to:

  1. Users who are not logged in.
18
  2. Users who have not left a comment on your blog.
19
  3. Or users who have not viewed a password protected post.
20
 
21
- The good news is that probably more than 99% of your visitors don't do any of
22
- the above! Those users who don't see the static files will still benefit
23
- because they will see regular WP-Cache cached files and your server won't be
24
- as busy as before. This plugin should help your server cope with a front page
25
- appearance on digg.com or other social networking site.

27
- This plugin is a modified version of the WP-Cache 2 plugin by Ricardo Galli Granada.
28
- His plugin is still available. We're standing on the shoulders of giants and benefiting
29
