[OT] Re: Coonection pooling

Can you give a few more specifics?  I am not sure what you are doing 
here and the context.  On pooling HttpConnection, you might look at 
http://jigsaw.w3.org/Doc/Programmer/api/org/w3c/www/protocol/http/HttpManager.html 
.  Are you intending to run this application within a webserver with Struts?
