MIME Types
You can associate a template or target file suffix with MIME-type information that you want to send with the file. You can create this association by placing a file called mimetypes at the top level of the Web Pages folder.
The following is a sample mimetypes file:
# Sample MIMEtypes file # Format is: <file-suffix> <whitespace> <MIME-descriptor> wml text/vnd.wap.wml wmls text/vnd.wap.wmlscript wbmp image/vnd.wap.wbmp wbxml application/vnd.wap.wbxml wmlc application/vnd.wap.wmlc wmlsc application/vnd.wap.wmlscriptc
