Disabling log4j output

[Todd Wells]

I'm using HttpClient from a custom Ant task, and at one point it spits
out 
 
[coreservice] INFO: I/O exception (java.net.ConnectException) caught
when processing request: Connection refused: connect
[coreservice] Mar 29, 2006 3:43:46 PM
org.apache.commons.httpclient.HttpMethodDirector executeWithRetry
[coreservice] INFO: Retrying request
 
In this case, the exception is expected (it's the desired result) and I
don't want it in the ant spew.  How can I disable HttpClient from
logging?
