Might also be able to implement this with a new form of listener. I thought it was sufficient to call response.flush. Maybe you have to actually write 0 bytes and then flush (like out.write(buffer, 0, 0); out.flush()). But, I haven't actually tried it so I can't confirm. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAksqlKwACgkQ9CaO5/Lv0PBrHQCgvR5Sce7ss+a6VFKM67qLA6+D S4sAn22RBcixFep3P06cZt8WCLPY9f1v =huNc -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
