Hi all, I have a question today: "How to detect client use Sock or Proxy via code PHP or Perl?" Note: I hope everyone serious discussion.
Hello! There could be one or more proxy servers between your computer and the web server. If the HTTP request includes the header "Via", or "X-Forwarded-For", then that's a strong indication that there is at least one proxy server somewhere along the line. If neither of those headers were present, that could mean that no proxy servers were involved, or it could mean that they just chose not to "reveal" themselves by adding those headers.
