Subject RE: Can httpclient fetch a url by given ip without querying dns?
Date Fri, 08 Jun 2007 13:24:48 GMT
I assume that would work, but you shouldn't really need to do that.  I
believe that the java.net.InetAddress class explicitly states that it
caches DNS lookup information to avoid that cost.

Look at the JavaDocs for java.net.InetAddress - it explains the
algorithm used and how to modify it.

In the end HttpClient isn't in control of the hostname-to-ip
resolution...unless there is some kind virtual name processing being
used.

Subject: Can httpclient fetch a url by given ip without querying dns?

Hi all,

when i use httpclient to fetch a lot of urls, i have already had the ip
of
host for each url. I don't want the httpclient to query dns for its ip,
because it will cost a lot of time. So can I explicitly set IP for each
url?


Thanks a lot,

Feng
