Re: [Htmlunit-user] how to get redirect chain

[Ahmed A. <asa...@ya...>]

Hi Wayne,
The logic is in WebClient.loadWebResponseFromWebConnection().
I am afraid there is no currently way to exactly know, except by copying the method on your code and do the same checking.
Hope that helps,
Ahmed

 Subject: [Htmlunit-user] how to get redirect chain
   
Hi,
 
I’m new to the alias and this may be an old topic. When I retrieve a page using htmlunit, there are usually some level of redirections. I would like to get the full redirection chain. One suggestion is the overwrite the HttpWebConnection. However, all I have is a WebRequest and WebResponse.
 
  public WebResponse getResponse(WebRequest request) throws IOException {
                super(request);
  }
 
I have 2 problems:
 
1.      It’s hard for me to tell if the web request is the original entry page. Or is it from loading a resource in the middle of parsing a non-entry page. I’m missing the “enclosed page” that triggered the http connection.
2.      In the response, I could try to parse and get the href. But I wonder if the redirect response is not well formatted, how do I guarantee the href I got is the page the parse is going to visit.
 
Wonder if anybody has been successful in retrieving the redirect chain.
 
Thanks a lot.
 
-Wayne
