Subject Re: Long receive time for chunked ssl response
Date Wed, 13 May 2009 23:06:13 GMT

Unfortunately, I there is no public access to the service in question. In theory any connection
involving SSL and chunked responses would reproduce-but that's in theory. If I can detect
this problem in a public site, I'll add it to the ticket (HTTPCORE-196).

Thank you

Processing a chunked SSL response of 221 characters, I found I was waiting over three seconds
for the entire response to be read. Upon investigation, this appears to be happening because
the decrypt method in SSLIOSession does not decrypt everything in the encrypted buffer at
one go. Because of this, portions of my response didn't get processed via the processing of
the events, but rather via the BaseIOReactor's validate method which means I experienced multiple
select interval timeouts prior to the message being fully processed. In reviewing the java
nio documentation for the unwrap method of the sslEngine, the comments in the javadoc state:
"This method will attempt to consume one complete SSL/TLS network packet". It appears that
one time through the decrypt method decrypted small packets with almost no data in them, leaving
encrypted data waiting. As an experiment, I changed the code in isAppInputReady in SSLIOSession
to call decrypt in a loop until everything in the en
crypted buffer was processed and bingo the response processed in under 5ms.
