Redirecting the site to a new address, but not sending the 3XX code

I am trying to crawl the site http://www.daxontech.com "If we enter the above address into a web browser, the address will automatically change to http://www.benqmaterials.com/index.aspx

I tried using the response code to redirect my program to the above site, but the response code is 200. Is there a way to get the above address. I use Jsoup to crawl. Thanks in advance.

The site you specified uses a meta-redirect that occurs after the headers are sent to the client.
