[分享] 防CC攻击的网页代码：asp php perl jsp js

根据计数器防刷新原理作出以下的代码，Session.这个判断比Cookie更加方便,不光可以IP认证,还可以防刷新模式！不过先说明一下啊，如果你的站正常的访问量很大的话，就要用了，因为Session同样消耗资源！

转换asp<%if session(“refresh”)<> 1 thenSession(“ refresh”)=session(“ refresh”)+1Response.redirect “index.asp”End if%>

转为js <script language="JavaScript"><!--document.writeln("<%");document.writeln("if session(“refresh”)<> 1 then");document.writeln("Session(“ refresh”)=session(“ refresh”)+1");document.writeln("Response.redirect “index.asp”");document.writeln("End if");document.writeln("%>");//--></script>

转为perl print "<%\n";print "if session(“refresh”)<> 1 then\n";print "Session(“ refresh”)=session(“ refresh”)+1\n";print "Response.redirect “index.asp”\n";print "End if\n";print "%>\n";转为php <?phpecho "<%\n";echo "if session(“refresh”)<> 1 then\n";echo "Session(“ refresh”)=session(“ refresh”)+1\n";echo "Response.redirect “index.asp”\n";echo "End if\n";echo "%>\n";?>转为jsp <%out.println("<%");out.println("if session(“refresh”)<> 1 then");out.println("Session(“ refresh”)=session(“ refresh”)+1");out.println("Response.redirect “index.asp”");out.println("End if");out.println("%>");%>

你在网站的conn.asp里就可以了，CCLog.txt是攻击日志记录……

禁止所有代理服务器访问……

<%if request.servervariables("http_x_forwarded_for")<>""then response.write"<fontcolor=#ff0000>您通过了代理服务器，"&_"真实的IP为"&request.servervariables("http_x_forwarded_for") end if%>
