I don't believe this is possible. You may be able to somewhat simulate 
what you want by using:


C:> bin\catalina.bat run > stdout_and_stderr.log

But you won't get the C:> prompt back, and your cmd.exe window will have 
to stay open until you stop the Tomcat process.
Aaand, I'm already wrong. Windows CAN redirect both stdout and stderr to 
two different places, and also to combine them just like you can on *nix:


bin\catalina.bat run 2>&1 > stdout_stderr.log

https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-xp/bb490982(v=technet.10)?redirectedfrom=MSDN

You still can't really "background" the process the way you can on *nix. 
Sure, you can get your command-prompt back, but if you kill cmd.exe, so 
does your child process die. And if you log out, that process dies as well.


Using the Windows Service is really the best way to do it on Windows.

Would it not be best to use CATALINA_BASE instead of CATALINA_HOME? The idea 
being that HOME should be the binaries, and BASE is mobile Just my .02 
worth.

Re: Maybe a stupid (Windows related) question

maybe redirect stderr to stdout then redirect to the log:  startup.bat 2>&1
1>yourFile.log
I believe that kind of redirection works in Windows as well as Linux (but
it's been a while since I had to do that sort of thing in Windows, so I may
be mistaken)

I think you want:

RewriteCond %{QUERY_STRING} p=10001
RewriteRule ^/f$ /myapp [R,L]

The prefix /apex is already a part of the context-path and should be 
removed from the URL patterns being matched. If you want to redirect to 
another web application, you need a fully-qualified redirect like this:


RewriteCond %{QUERY_STRING} p=10001
RewriteRule ^/f$ https://www.google.com/ [R,L]

Hi Chris and Mark,

Thank you both for your input.

I arrived at an sru.xml file in conf\Catalina\localhost, containing:

Now I’m reminded why I wanted it to be configurable – it’s behind a load

the network route the calling service will take.


If all requests (even "local" ones) will be going through the 
load-balancer (or even not, I guess), then you should configure the 
RemoteIpValve[1]. This will allow the load balancer to send you the 
original IP of the actual client through HTTP headers, and those will be 
used in log files, etc.


I *think* it will use those same remote IPs for your RemoteAddrValve, 
but you must make sure to have the RemoteIPValve configured to run 
*before* the RemoteAddrValve so that the addresses have a chance to be 
copied from those headers before they are evaluated for local-ness.


Ask your LB operator to enable the "X-Forwarded-For" header on the LB 
which is how that information it typically sent to back-end servers.


Hope that helps,
