Why wouldn't nginx in front of Apache/mod_wsgi work for 5MB uploads. I
would suggest that that is actually a better setup for uploads than
connecting direct to Apache/mod_wsgi. The reason is that nginx buffers
uploads before pushing it through to Apache/mod_wsgi. This means that
nginx isolates Apache/mod_wsgi from slow clients and ensures that
Apache/mod_wsgi is only involved when the complete uploaded file is
available, thereby ensuring that Apache/mod_wsgi is utilised the most
efficiently. The only issue with having nginx in front for this case
is that upload progress bars probably aren't going to work because of
the buffering that nginx does before pushing content through.
