Hi all,

I need to test if a url exists. I used url.exists() in RCurl package

library(RCurl)

however the test result is kind of weird. For example,

> url.exists("http://www.amazon.com")
[1] FALSE

although www.amazon.com<http://www.amazon.com> is a valid url. Does anybody know how to use that function correctly or the other way to test url existence?

Thanks.

HXD
