Logs are filling up with httpclient.wire.content dumps. How can I turn it off?

Question

My catalina logs are filling up with gobs of statements like:

/logs/catalina.out:2010-05-05 02:57:19,611 [Thread-19] DEBUG httpclient.wire.content - >> "[0x4]
[0xc][0xd9][0xf4][0xa2]MA[0xed][0xc2][0x93][0x1b][0x15][0xfe],[0xe]h[0xb0][0x1f][0xff][0xd6][0xfb]
[0x8f]O[0xd4][0xc4]0[0xab][0x80][0xe8][0xe4][0xf2][\r]I&[0xaa][0xd2]BQ[0xdb](zq[0xcd]ac[0xa8]

on and on forever.

I searched every config file in both tomcat and apache for the statements that purportedly turn this on as described here:

http://hc.apache.org/httpclient-3.x/logging.html

And I don't see where this logging has been enabled. No other .war I deployed does this. The log4j configuration block in the app isn't doing it.

I also tried to turn it off with statements like this:

org.apache.commons.httpclient.wire=SEVERE

or

org.apache.commons.httpclient.wire.content=SEVERE

or

httpclient.wire.content=SEVERE

in my tomcat/conf/logging.properties file, and that didn't stop it

I'm using an S3 library for grails that may be the source for these. However when I run this application on my development machine (in both develop and deploy configs), I'm not seeing it.

And a related question: When would I want to use these "wire logs?"

For Slf4J:

<dependencies>
    <!-- LOGGING -->
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>jcl-over-slf4j</artifactId>
        <version>1.5.9-RC0</version>
    </dependency>
    <dependency>
        <groupId>ch.qos.logback</groupId>
        <artifactId>logback-classic</artifactId>
        <version>0.9.17</version>
    </dependency>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-api</artifactId>
        <version>1.5.9-RC0</version>
    </dependency>
</dependencies>

And put logback.xml in your classpath with the content below:

<configuration>
    <!-- LOGBACK logging config file, see http://logback.qos.ch/manual/joran.html -->
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <layout class="ch.qos.logback.classic.PatternLayout">
            <!-- http://logback.qos.ch/manual/layouts.html#ClassicPatternLayout -->
            <Pattern>%-5level %msg [%logger{16} %d{HH:mm:ss}]%n</Pattern>
        </layout>
    </appender>

    <root level="debug">
        <appender-ref ref="STDOUT" />
    </root>
    <logger name="org.apache" level="WARN" />
    <logger name="org.apache.axis2" level="WARN" />
    <logger name="org.apache.axiom" level="WARN" />
    <logger name="httpclient.wire" level="WARN" />
</configuration>
