You can use .htaccess to define your own MIME types. What this means is you can associated file types with actions to be performed.

How do you use this? Let’s stay you want .DOC files to be interpreted as .TXT files. Modify the lines below:

AddType text/plain .txt


AddType text/plain .txt .doc

You must perform an additional step if your server only supports the .SHTML file type for SSI files and you want a .HTML file to also perform SSI. Simply modify the MIME type from:

AddType text/html                       .html .htm
AddType text/x-server-parsed-html       .shtml .sht


    AddType text/html                       .htm
    AddType text/x-server-parsed-html       .shtml .sht .html
    AddHandler server-parsed                .shtml .sht .html

Note the use of the “AddHandler” optoin to indicate the server side handlers.

Use this with caution, as ALL files with a .HTML file type will be interpreted as .SHTML. You can see, however, how convenient this can be.

The table below shows each of the MIME types and some of the associations.
