AddHandler directive
Syntax: AddHandler handler-name extension [extension] ...
Context: server config, virtual host, directory, .htaccess
Override: FileInfo
Status: Base
Module: mod_mime
Compatibility: AddHandler is only available in Apache 1.1 and later
AddHandler maps the filename extensions extension to the handler handler-name. This mapping is added to any already in force, overriding any mappings that already exist for the same extension. For example, to activate CGI scripts with the file extension \".cgi\", you might use:
AddHandler cgi-script .cgi
Once that has been put into your srm.conf or httpd.conf file, any file containing the \".cgi\" extension will be treated as a CGI program.
The extension argument is case-insensitive, and can be specified with or without a leading dot.
du kan NÆSTEN altid få lov at sætte din .htaccess fil... og så skulle det være muligt at ændre... har du ikke adgang til det, vil det være et problem...
