How to set request contains HTTP header with "Connection: Keep-Alive" in Axis

[Zhou Jian Han]

Hi, 
I look into the Class 'Call' which has setTimeOut(Integer timeout), it takes 
millisec as param. But How can I set a request which has no timeout, and 
generate request contains an HTTP header with "Connection:keep-alive". 
Should I set timeout=-1??   

Many Thanks,
Georgia
