Hello Tomcat developers,
I'm Konstantin Preißer, a german student of Computer Science. I'm developing
programs with Java and .Net/C#.
Since I have been using Tomcat with IIS (JK ISAPI Connector) for quite some
time now, I wondered if it may be an option for the Apache software
ble to get chunks from other SPDY streams. Whereas with AJP, IIS would
simply stop reading from the AJP connection which doesn't affect other
clients.) Wouldn't this be a problem? (But probably I'm just missing somethi
;t be a problem with this when implementing server-to-server
communication. So maybe I can try to start an IIS SPDY connector. :)
Thanks,
Konstantin Preißer

me to SPDY, so I think I will try that instead. I agree that it might be a good
idea to collaborate on such a project. :)

Hello!
Some time ago, I wrote about a possible alternative IIS AJP Connector
implementation [1] that is written in C# and uses the new IIS 7/8 module
pipeline, which allows to insert managed modules (.Net) in the request pipeline.

The SPDY client also supports flow control (which was added in SPDY/3) so that
if a slow client connects to IIS, IIS does not have to buffer the complete
request body received by Tomcat before it can send it to the client, while
concurrently serving other HTTP requests over that SPDY connecti

Yes, I agree. I could modify the SPDY redirector so that it appends x-headers
for the client IP etc. (but currently I don't know much about transferring
certificates - is that what "CREDENTIAL" frame in SPDY is
possible to set up Jetty's SPDY
connector to not use TLS/NPN, so that you don't need a SSL certificate and the
java NPN tunnel).
I would be happy if you have some feedback :)

ages that has been constructed by pressing down the mouse
button, moving the mouse and releasing the mouse button, is complete. However,
because every Path/DrawMessage instance contains both the start and end point
(instead of only containing one point which would mean the drawing code would
need to keep the last Path element until the lastInChain flag is set to true),
it is not used.
I do not know why I kept the flag when committing the drawboard example, but I
think the flag can be removed at Javascript side as well. I will look into it.

e some insight of why Grahpics2D.dispose() may cause a hang on
shutdown? I have never seen .dispose() causing a hang, at least not on Windows.
If it hangs, might this be a result of different threads using the Grahpics
