How to restrict the size of file being uploaded apache + django

Question

How to restrict the size of file being uploaded. I am using django 1.1 with apache. Can I use apache for this and show some html error page if say size is bigger then 100MB.

If you want to get the file size before uploading begins you will need to use Flash or a Java applet.

Writing a custom upload handler is the best approach. I think something like the following would work (untested). It terminates the upload as early as possible.

from django.conf import settings
from django.core.files.uploadhandler import FileUploadHandler, StopUpload

class MaxSizeUploadHandler(FileUploadHandler):
    """
    This test upload handler terminates the connection for 
    files bigger than settings.MAX_UPLOAD_SIZE
    """

    def __init__(self, request=None):
        super(MaxSizeUploadHandler, self).__init__(request)


    def handle_raw_input(self, input_data, META, content_length, boundary, encoding=None):
        if content_length > settings.MAX_UPLOAD_SIZE:
            raise StopUpload(connection_reset=True)
