weird problem, link sometimes no response.

[Henry Chen]

I found this is really weird. When I clicked some DirectLinks, I got stuck
and the page didn't proceed. But if I click the same link once more, the
result showed up immediately. It didn't quite noticable when I developed the
website on my own machine. It happened a lot especially when I access the
website remotely. Does any one know what the problem is here? Thanks a lot.
