Help on getting started using HttpClient

Hi guys,

I am using HttpClient for the first time. Wrote a program on the same lines
as described in the tutorial
section on the HttpClient documentation website

Here is the output I get when I invoked one of the URL's using the GetMethod

<HTML>
<!-- File: redirectmeta.html -->
<HEAD>
<TITLE>Livelink - Redirection</TITLE>
<META HTTP-EQUIV="Refresh" CONTENT="0;
URL=/customapp/view/ASE_Roles.html?func=loadParentPage">
</HEAD>
</HTML>

Now my question, how do I get the HttpClient to go to this redirect url and
retrieve the actual content.

Could any of you guide me to a website/book which has some examples and
detailed documentation 

Any help in this regard is appreciated.

Thanks,
Prasad

Prasad,

Start off by taking a look at the HttpClient redirect guide

http://jakarta.apache.org/commons/httpclient/redirects.html

If the document does answer all your questions, get back to us

Prasad,

Let me explain, that normally redirects are caused by the Location HTTP 
header and a redirect status code.
But the redirect in your case is requested by the body of the HTTP 
message, that is the HTML code. HttpClient is not HTML specific and not 
a web browser. Therefore HttpClient does not look into the HTTP message 
body and can not interprete HTML. You will need to parse the HTML code 
and find the meta tag yourself. You could either just write a simple 
parser for this specific purpose or employ a full-blown HTML parser [1].
