Available as an External module in Apache 1.1 and later.</p> <h2>Summary</h2> <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> <h2>Directives</h2> <ul> <li><a href="#checkspelling">CheckSpelling</a></li> </ul> <hr /> <!-- the HR is part of the directive description --> <h2><a id="checkspelling" name="checkspelling">CheckSpelling</a> directive</h2> <a href="directive-dict.html#Syntax" rel="Help"><strong>Syntax:</strong></a> CheckSpelling on|off<br /> <a href="directive-dict.html#Default" rel="Help"><strong>Default:</strong></a> <code>CheckSpelling Off</code><br /> <a href="directive-dict.html#Context" rel="Help"><strong>Context:</strong></a> server config, virtual host, directory, .htaccess<br /> <a href="directive-dict.html#Override" rel="Help"><strong>Override:</strong></a> Options <br /> <a href="directive-dict.html#Status" rel="Help"><strong>Status:</strong></a> Base<br /> <a href="directive-dict.html#Module" rel="Help"><strong>Module:</strong></a> mod_speling<br /> <a href="directive-dict.html#Compatibility" rel="Help"><strong>Compatibility:</strong></a> 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.
