The MIMETypes object class provides a single point to hold onto all
the registered mimetypes, and their association extensions. It's
used by the mimetypes function to determine the appropriate content
type to return to a client.
c C s t i d S( să Loads a default mapping of extensions and mimetypes
These are suitable for most web applications by default.
Additional types can be added with the using the mimetypes
module.

sE Check the PATH_INFO of the current request and clients HTTP Accept
to attempt to use the appropriate mime-type
If a content-type is matched, the appropriate response content
type is set as well.
This works best with URLs that end in extensions that differentiate
content-type. Examples: http://example.com/example,
http://example.com/example.xml, http://example.com/example.csv
Since browsers generally allow for any content-type, but should be
sent HTML when possible, the html mimetype check should always come
first, as shown in the example below.
Example::
# some code likely in environment.py
MIMETypes.init()
MIMETypes.add_alias('html', 'text/html')
MIMETypes.add_alias('xml', 'application/xml')
MIMETypes.add_alias('csv', 'text/csv')
# code in a controller
def somaction(self):
# prepare a bunch of data
# ......
# prepare MIMETypes object
m = MIMETypes(request.environ)
if m.mimetype('html'):
return render('/some/template.html')
elif m.mimetype('atom'):
return render('/some/xml_template.xml')
elif m.mimetype('csv'):
# write the data to a csv file
return csvfile
