------- Additional Comments From sachinh@singnet.com.sg  2002-07-23 14:33 -------
In the present version of HttpMultiClient, setting of proxies must be done at 
the entire HttpMultiClient level, which may not be ideal requirement. An 
application may want to use only one instance of HttpMultiClient to serve 
internal as well as external (behind firewalls) hosts and hence setting the 
proxy on the HMC will fail to work with internal hosts. Moreover, it may be 
desired to use a different proxy server for different host connections.  

What could be a good solution? 

Having proxy host/port setters in the UrlMethod class may not be ideal. I 
suggest adding a proxyHost, proxyPort and useProxy (boolean) as parameters to 
the HttpMultiClient.execute() method itself. If no proxy host and port is 
specified and useProxy is true, the default value (set in HMC) will be used. 

Sometimes it may also be desirable to have a support for multiple proxies. So 
if the first one is down, the second one is used, and so on. An elegant 
solution maybe if we have a new class to handle proxy related affairs, 
including hand shaking, authentication, daisy chaining of proxies, and other 
proxy rules.
