AJP flush packets?
Hi,
i see, you're developing Tomcat 6.0.
Will Tomcat 6.0 send flush packets, when the flush()-method of the
OutputStreams or the Writers are called?
It's something really needed by mod_proxy_ajp, mod_jk, and so on to
property transport flushes to.
Greetings,
Sven

This has been done on October 29th in revision r468936 fpr TC 5.5 too.
It should be part of 5.5.21, which hat not been scheduled yet.

Rainer

I have one more question:
Is this going to be "backported" to Tomcat 5.5?

Not really, but in that case we would need to
extend the AJP protocol with something that would
notify the mod_jk/mod_proxy_ajp that explicit flush()
was requested.
That would of course break any mod_jk/mod_proxy not
having those extensions.
With empty packet the previous versions will simply
write 0 bytes to the client, while 1.2.20 and up
will call the web server flush.

Mladen.

Hi,

during this month.

Did it really need to be done like that? :-(
Well, not matter how, but it was done, so it's a reason to be happy :-)

When out.flush() is called an empty data packet is sent.

The implementation is in the SVN both for mod_jk
and mod_proxy_ajp. You will have to wait for the
next release (mod_jk 1.2.20) if you don't wish to
use the SVN builds.
