Done

Bug 59399 - Tomcat doesn't support setting the response code for http
-> https redirect

That might take a little longer, working on it

Yep, you're correct. UrlRewrite is not the answer, it's out of the picture.
it's just CONFIDENTIAL and the standard port 80/443 connectors that I
have to deal with

Well I wouldn't call it a bug really, more of a missing feature that
would be nice to have
I've never submitted a bug before I don't really know where to start ...

Ah ... http://tomcat.apache.org/bugreport.html



I wouldn't call it a bug, more of an 'enhancement'.
I'll give it a go, after all I can only get shouted at :-)

As it happens I'm currently setting up a mirror of my new live CentOS
systemd server as my new dev box (currently on Ubuntu)
The first thing I was going to do was get the source of Tomcat 7 and
try to build it

Jeez, contribute to Tomcat eh, that would be something wouldn't it?

Anyway thanks to all for all the help and for your patience,
I'll figure out how the bug report thing works and submit an enhancement

Re: performance of tomcat 8 is less than tomcat 6

Yes I tried the NIO and NIO2 but not seen much difference. The TPS only 
increased 3K  with NIO2.
Can you try it with nio enabled in tomcat 6 and see, if that is slower, 
too? Same with bio and tomcat 8 and see if it is better?

Hi Christopher,
PFA, the requested XMLs. Just want to highlight that tomcat 8  is not

able to use the CPU usage. I have tried maxThread 200,300,400 but result is 
same sometimes even less TPS.

Hi, I am using tomcat 6 in my product. I am planning to upgrade to
tomcat 8 as tomcat is going to EoS in Dec-2016. I have just taken
the performance of Tomcat 8 and found the 70% less performance
compared to tomcat 6. See the below results Tomcat 6 is giving
167473.2/s whereas tomcat 8 is giving 100436.6/s I have just
compared with two standalone tomcat which is just hitting the
HelloWorld servlet available in example.

Kindly let me know what need to configure to boost the performance.
