-
- <p>Requests to documents sometimes cannot be served by the core
- apache server because the request was misspelled or
- miscapitalized. This module addresses this problem by trying to
- find a matching document, even after all other modules gave up.
- It does its work by comparing each document name in the
- requested directory against the requested document name
- <strong>without regard to case</strong>, and allowing
- <strong>up to one misspelling</strong> (character insertion /
- omission / transposition or wrong character). A list is built
- with all document names which were matched using this
- strategy.</p>
-
- <p>If, after scanning the directory,</p>
-
- <ul>
- <li>no matching document was found, Apache will proceed as
- usual and return a "document not found" error.</li>
-
- <li>only one document is found that "almost" matches the
- request, then it is returned in the form of a redirection
- response.</li>
-
- <li>more than one document with a close match was found, then
- the list of the matches is returned to the client, and the
- client can select the correct candidate.</li>
- </ul>

- <compatibility>CheckSpelling was available as a separately available
- module for Apache 1.1, but was limited to miscapitalizations. As
- of Apache 1.3, it is part of the Apache distribution. Prior to Apache
- 1.3.2, the <code>CheckSpelling</code> directive was only available in the
- "server" and "virtual host" contexts.</compatibility>
-
- <usage>
-
- <p>This directive enables or disables the spelling module. When
- enabled, keep in mind that</p>
-
- <ul>
- <li>the directory scan which is necessary for the spelling
- correction will have an impact on the server's performance
- when many spelling corrections have to be performed at the
- same time.</li>
-
- <li>the document trees should not contain sensitive files
- which could be matched inadvertently by a spelling
- "correction".</li>
-
- <li>the module is unable to correct misspelled user names (as
- in <code>http://my.host/~apahce/</code>), just file names or
- directory names.</li>
-
- <li>spelling corrections apply strictly to existing files, so
- a request for the <code><Location /status></code> may
- get incorrectly treated as the negotiated file
- "<code>/stats.html</code>".</li>
- </ul>
