I'm not so sure how happy that would make Remy. It wouldn't be too hard to have Connector.createResponse check the protocol, and if it's AJP/1.3 then set the buffer size to 16386 (currently it's not possible to decrease the buffer size). It wouldn't be that hard to add buffering to JkInputStream so that it always tries to write out a 8184 packet. This would also prevent fracturing in the event that the webapp programmer decides to call response.setBufferSize herself. The downside would be an extra arraycopy when writing (and, of course, an extra 8184*numThreads bytes of memory used :). > Regards, > Mladen. > > --------------------------------------------------------------------- > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > > This message is intended only for the use of the person(s) listed above as the intended recipient(s), and may contain information that is PRIVILEGED and CONFIDENTIAL.
