I apologize that the google translation makes no sense, but the goal is that I can make settings for the header from PHP scripts in B4J. Specifically this part of PHP code:
If you want to send requests from b4j then you should use okhttputils.
Yes, you can set referer and url headers.
You just need to know the Headername (whats behind the CURLOPT_REFERER or CURLOPT_URL) to set it.
Maybe you should learn english and do not rely on faulty google translations.
