Apache Module mod_speling

Available Languages: en | + ja | + ko

+ + + +

Description:	Attempts to correct mistaken URLs that +users might have entered by ignoring capitalization and by +allowing up to one misspelling
Status:	Extension
Module Identifier:	speling_module
Source File:	mod_speling.c

Summary

+ + +

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 + without regard to case, and allowing + up to one misspelling (character insertion / + omission / transposition or wrong character). A list is built + with all document names which were matched using this + strategy.

+ +

If, after scanning the directory,

+ +

no matching document was found, Apache will proceed as + usual and return a "document not found" error.
only one document is found that "almost" matches the + request, then it is returned in the form of a redirection + response.
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.

Directives

CheckSpelling

+ +

CheckSpelling Directive

+ + + + + + + + + +

Description:	Enables the spelling +module
Syntax:	`CheckSpelling on\|off`
Default:	`CheckSpelling Off`
Context:	server config, virtual host, directory, .htaccess
Override:	Options
Status:	Extension
Module:	mod_speling
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 `CheckSpelling` directive was only available in the +"server" and "virtual host" contexts.

+ +

This directive enables or disables the spelling module. When + enabled, keep in mind that

+ +

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.
the document trees should not contain sensitive files + which could be matched inadvertently by a spelling + "correction".
the module is unable to correct misspelled user names (as + in http://my.host/~apahce/), just file names or + directory names.
spelling corrections apply strictly to existing files, so + a request for the <Location /status> may + get incorrectly treated as the negotiated file + "/stats.html".
