Revision [6064]
This is an old revision of RobotFriendly made by BarkerJr on 2005-02-16 23:01:14.
To start, you probably don’t want deleted pages to show up in the SearchEngines’ indices. There are a few ways to do this.
Robots Meta Tag
Contributed by BarkerJrThis patch adds the robots meta tag to the header of deleted pages. This works good, but some SearchEngines don’t support it, and will still show up in some indexes. Sending 404 (see below) works on all SearchEngines, but can sometimes display incorrectly due to a “feature” in Internet Explorer (see the note below it).

To install a patch, place it in a file in your wiki's directory and execute: patch -p1 < filename
Sending 404 Not Found
Contributed by DotMGModify ./handlers/page/show.php like this :
- if (!$this->page)
- {
- print("<p>This page doesn't exist yet. Maybe you want to <a href=\"".$this->Href("edit")."\">create</a> it?</p></div>");
- }
Note: On IE, there is a number of bytes required, and if the length of body is less than this limit, IE displays its own default content. But normally, the page should always display the content we expect (This page doesn't exist. Maybe you want to create it).
