I tried both sites and got similar results.  Works fine on Win98 (Is XP 
something new?)

http://henrietta_bowman.tripod.com
Blackberry (JavaScript disabled) Error 400 bad Request
OpenBSD lynx and wget - name resolution errors.

$ host henrietta_bowman.tripod.com
henrietta_bowman.tripod.com has address 209.202.226.100

So I added the following line to /etc/hosts
209.202.226.100 henrietta_bowman.tripod.com

And was then able to access the webpage with lynx.


http://www.christianpost.com/
Blackberry (with JavaScript disabled) works fine.
OpenBSD lynx and wget - 403 Forbidden

$ host christianpost.com
christianpost.com has address 64.127.105.166
christianpost.com mail is handled by 10 mail.christianpost.com.

Adding entry to /etc/hosts makes no difference.

This site comes up with a couple of red flags here:
http://www.dnsreport.com/tools/dnsreport.ch?domain=christianpost.com

But when I query the various name servers (chtoday.com and verecom.com) 
they all (4) to respond with 64.127.105.166
