This Applet will tell you what your server is sending for MIME types and what it should be. If you discover errors in the what it server is sending, notify the ISP (Internet Service Provider). If you discover errors in what the MIME type should be, email me at .
MIME types are referred to in the RFC 1945 HTTP 1.0 specification as media types types. The content-type and content-encoding fields in the RFC 1945 HTTP header together give a hint to the receiver what kind of data has just been handed to it.
IANA is responsible for assigning new MIME types. Unfortunately naming is even more chaotic than the extensions, often with several conflicting MIME types for each extension. Unfortunately, MIME has made the problem it was intended to solve even worse. It matters not what the official name is, but the MIME name configured in the majority of the world’s browsers is. I have found Filext.com the most useful source.

Eventually this printable encoding will be dropped. Base64 encoding, for example, adds 33% overhead to the transmitted message size. The Internet is now almost completely converted to 8-bit, so it should not usually be necessary.

There is a database of MIME types and extensions in the Windows Registry. At some point I will mine it for more entries. HKEY_CLASSES_ROOT\ MIME \Database\Content Type\application/x-java-jnlp-file. You can get a list of Windows extensions and associated MIME types by typing assoc at the command prompt.
HTML (Hypertext Markup Language) forms use application/x-www-form-urlencoded, though there is no filename.
You can get the MIME type for a given file using java.net.FileNameMap.getContentTypeFor(filename)
Here is one offial source for MIME types: The definitive IANA list however it has only a fraction of the total is use.
