Hi All, Recently I have had a robot that has been crawling my website, I am not sure why but I am sure that it has malicious purposes. I continually block it using htaccess and then it will be back a week later under different IP Addresses. I have noticed that it always has the same operating system, browser and screen resolution which is why I know it is the same bot. What I would like to do is block any visits that fit all of these parameters: Operating system: Linux Screen Res: 800x600 Browser: Safari Browser Version: 533.3 I doubt that I would lose many legitimate users that fit all of these parameters, if any. I am not sure if this can be done with htaccess or if it would be easier to do it in asp.net. Any advice, pointers or examples would be much appreciated. Thanks in advance, Cam
