You could do this in a few stages: #1 Use an async XMLHttpRequest on the client side to POST the file to your file upload servlet; in the URL for the post use a unique identifier, say MY-ID #2 Override make_file /w your own that monitors how much of the file's content has been sent; store that in a global mapping using MY-ID as the key #3 Create a monitor URL on your server that reads the mapping and returns an hour glass or something /w a refresh page #4 When you send your application request; open up an iframe /w refresh setting to that monitor URL (using MY-ID) Although, you've probably already done something similar... | To do this I subclassed cgi.FieldStorage but when I finished I had | modified most of the non-trivial methods just to hook in something to | monitor the transfer progress, oops. | | Has anyone else found FieldStorage insufficient for certain tasks? | Is there a general need for a more flexible FieldStorage replacement? I've found make_file sufficient for all of my needs (so far) Best, Clark _______________________________________________ Web-SIG mailing list Web-SIG@python.org Web SIG: http://www.python.org/sigs/web-sig Unsubscribe: http://mail.python.org/mailman/options/web-sig/archive%40mail-archive.com
