On the face of it, this looks like it should work. What does
your SetDoNoLogFilter code look like?

Perhaps that's my problem, I do not have any code to support this.
I think for this to work as I have it now I need an existing Java
filter class.
Hah. Okay, so then what does SetDoNotLogFilter refer to? Or were you
just hoping that would magically work?
Yes, I was hoping for a little magic. Conditional logging seems like such a
basic concept that I am greatly surprised to have to jump through hoops to
achieve it. The documentation I've read for filters seems to be intended for an
audience with prior webapp development experience. Unfortunately I do not fall
into that crowd, so I was unaware a filter had to be related to another piece
of configuration/code. I am looking into the url-rewrite filter as suggested.
Thanks!

Mark's response was prescient: you probably want to use the
url-rewrite filter because it will avoid you having to write any new
code.

Maximum HTTP parameters
My webapp needs to pass several thousand parameters in an HTTP POST request. I am required to use RHEL's tomcat packages (currently on 6.0.24). I figured out Red Hat has capped the maximum HTTP parameters at 512 and to get around it, I have to add the Java parameter -Dorg.apache.tomcat.util.http.Parameters.MAX_COUNT=5000 to the JVM. I know this isn't strictly a Tomcat issue since the problem is Red Hat's doing, but is anyone aware if it is possible to set this value to unlimited? I tried setting it to 0 and -1 but they were treated as literal values. -- Kris Dames This email contains information which may be PROPRIETARY IN NATURE OR OTHERWISE PROTECTED BY LAW FROM DISCLOSURE and is intended only for the use of the addresses(s) named above.

What if my database is unavailable at startup?
Hi, I use tomcat 6 and have noticed if a database is not available when tomcat starts, tomcat will not try to connect once the database becomes available. Tomcat must be restarted to establish the database connection. What are best practices regarding this? Is there a way in tomcat to get it to automatically retry so I don't have to restart tomcat? I use DBCP but am willing to try some other pool. -- Kris D.

RE: What if my database is unavailable at startup?
can/should we assume that your URL is referencing a database on a different machine, same network/intranet/LAN? url=jdbc:oracle:thin:@x.y.com:1521:x it seems as though OP is referencing a database somewhere on the 'internet'. The database server is on the same network, different machine. -- Kris D.
