Help on the httpclient

[Pan John-CXP001 <jo...@motorola.com>]

I wrote a simple http client to talk with the http server running on one
of our routers. The server version is 1.0.  However, when I do a GET on
the router, I got the following error message.
 
2005-7-19 20:35:10
org.apache.commons.httpclient.auth.AuthChallengeProcessor
selectAuthScheme
info: basic authentication scheme selected
Fatal protocol violation: The server 10.79.134.111 failed to respond
with a valid HTTP response

When I use the IE browser to access the same webpage
"http://10.79.134.111/execcmd?sh&vers
<http://10.79.134.111/execcmd?sh&vers> &" on my router, it works fine.
I am confused since I don't know it's my client problem or it's router's
http server problem.
 
Any help will be appreciated;
