Hi atcroft, Corion, ikegami, jesuashok, McDarren and All,

Thank you all for your kind wisdom :)

atcroft, thanks. I am much much more clear at where I am heading now.

I do agree with you all that the proxy way is the best way, but since the resources I've been given for this work is scarce (one IBM xseries 220 windows2k server with 256MB ram and 34GB scsi harddisk as a search portal + 2 existing DNS Sun Sparc stations), I think may be option 2 gives the IBM server less load. please correct me if I am wrong.

On the web server side, I guess I have the choice of either using the existing IIS 5.0 server or the Apache server for my portal. Do I have to code using an extension/API of some sort to achieve what I want to do?

Cheers and Best Regards,

Wilson
