To locate the Log file where the logs are written, or the Config file used to configure logging, go to the Administration Page, and in the General tab, you can view the location of these files.

        edit the file listed as the Config file in the Administration
          Page, and add the following
        lines:
      log4j.category.org.apache.http.impl.conn=debug
log4j.category.org.apache.http.impl.client=debug
log4j.category.org.apache.http.client=debug
log4j.category.org.apache.http.headers=debug Making changes to this file requires that you restart the
          application.
    Warning: 
After you finish your debugging session, remember to revert this configuration file back
          to its original content to avoid performance issues.
