Here is an example of using AddType directives .htaccess files to introduce new content types for mobile markup mapped to

file extensions. One directive is allowed per line of the configuration file:


# Add Mobile MIME types for xhtml, wml, wbmp and wmls file extensions
AddType application/vnd.wap.xhtml+xml .xhtml
AddType text/vnd.wap.wml .wml
AddType image/vnd.wap.wbmp .wbmp
AddType text/vnd.wap.wmlscript .wmls

A single AddType directive can associate multiple file extensions with the same MIME type. Here is an example that associates

xhtml and xhtm file extensions with the application/vnd.wap.xhtml+xml content type:


AddType application/vnd.wap.xhtml+xml .xhtml .xhtm



 

The configuration in .htaccess files affects the directory in which the file is placed and all subdirectories. But, there is

no inheritance for directives in .htaccess configuration. The .htaccess file nearest to the target web document is the

configuration file used to serve the document. Make sure to upload your .htaccess file into the appropriate web server

location.

There are performance implications when using multiple .htaccess files across a website, especially if a single Apache

instance hosts multiple domains. Because configuration is distributed across the file system, Apache must inspect the

directory hierachy to determine which .htaccess file applies for a HTTP request. Think carefully when creating multiple

.htaccess configuration files and centralize wherever possible.
