If you are on apache 2.2 i strongly suggest you to use mod_proxy_uwsgi (sadly on apache2.4 it looks like it has some problem) it should not have this kind of limits. By the way i will investigate if we can improve mod_uwsgi to support chunked input -- Roberto De Ioris http://unbit.it _______________________________________________ uWSGI mailing list [email protected] http://lists.unbit.it/cgi-bin/mailman/listinfo/uwsgi
