+Checks if an HTTP proxy is open.
+
+The script attempts to connect to www.google.com through the proxy and checks
+for a <code>Server: gws</code> header field in the response.
+
+If the target is an open proxy, this script will cause the target to retrieve a
+web page from www.google.com.

+-- Changelog: Added explode() function. Header-only matching now works.
+--   * Fixed set_timeout
+--   * Fixed some \r\n's

+--   * Match case-insensitively against "^Server: gws" rather than
