Extending the CTP Server Content Type Associations

The embedded server in CTP has a built-in table that associates file extensions with Content-Types. This article describes how to extend the table without having to rebuild the server. This article is intended for administrators who discover that they need to serve non-standard file types.

The standard file types and their associated Content-Types are:

application	application/x-ms-application
avi	video/x-msvideo
css	text/css;charset=UTF-8
csv	text/csv;charset=UTF-8
dcm	application/dicom
deploy	application/octet-stream
docx	application/vnd.openxmlformats-officedocument.wordprocessingml.document
dotx	application/vnd.openxmlformats-officedocument.wordprocessingml.template
gif	image/gif
htm	text/html;charset=UTF-8
html	text/html;charset=UTF-8
jar	application/java-archive
jnlp	application/x-java-jnlp-file;charset=UTF-8
jpeg	image/jpeg
jpg	image/jpeg
js	text/javascript;charset=UTF-8
manifest	application/x-ms-manifest
md	application/unknown
mp4	video/mp4
mpeg	video/mpeg
mpg	video/mpg
oga	audio/oga
ogg	video/ogg
ogv	video/ogg
pdf	application/pdf
png	image/png
pot	application/vnd.ms-powerpoint
potx	application/vnd.openxmlformats-officedocument.presentationml.template
pps	application/vnd.ms-powerpoint
ppsx	application/vnd.openxmlformats-officedocument.presentationml.slideshow
ppt	application/vnd.ms-powerpoint
pptx	application/vnd.openxmlformats-officedocument.presentationml.presentation
svg	image/xvg+xml
swf	application/x-shockwave-flash
txt	text/plain;charset=UTF-8
wav	audio/wav
webm	video/webm
wmv	video/x-ms-wmv
xlsx	application/vnd.openxmlformats-officedocument.spreadsheetml.sheet
xltx	application/vnd.openxmlformats-officedocument.spreadsheetml.template
xml	text/xml;charset=UTF-8
zip	application/zip

To add new file types or to override ones in the standard table, create a file called ContentTypes.xml in the CTP directory. The structure of the file is:

<ContentTypes>
    <File
        ext="extension"
        type="content-type"/>
    ...
