There is already an answered question on this topic:
Limit a form post size with Apache / Django
but I'm not sure what this means: "If, for example, you are permitting file upload to a particular location" (source: http://httpd.apache.org/docs/2.2/mod/core.html#limitrequestbody) - which location I'm uploading a file to when doing that under Django (WSGI)? Is that directive Apache-wide, or should it be used on some specific folder?
