The MIME type returned for an extension can be overriden in the AOLserver config file, and new mappings can be added, e.g.

   ns_section "ns/mimetypes"
   ns_param  ".xls"        "application/vnd.ms-excel"      ;# Add a mapping for Excel files
   ns_param  ".sjis_html"  "text/html; charset=shift_jis"  ;# Adding a mapping, specifing charset
   ns_param  ".adp"        "text/html; charset=UTF-8"      ;# Overriding an existing mapping

The MIME type to be returned for files with unrecognized or missing extensions can also be specified in the "ns/mimetypes" section of the config file, e.g.

   ns_section "ns/mimetypes"
   ns_param  default      "*/*"  ;# MIME type for unrecognized extension.
   ns_param  noextension  "*/*"  ;# MIME type for missing extension.

If default is not configured, "*/*" will be returned for files with unrecognized extensions. If noextension is not configured, the MIME type configured as default (or "*/*") will be used.

EXAMPLES

(Assuming configured with the examples above)

   % ns_guesstype "hello.jpg"
   image/jpeg

   % ns_guesstype "hello.xls"
   application/vnd.ms-excel

   % ns_guesstype "hello.html"
   text/html; charset=iso-8859-1
