I have installed clickstream into my portal and it works. I tested it on many
computers and works ok.
But in one computer I get message below. This computer was connected to Internet
through modem to one company.
Then I connect with my computer to the Internet through modem to the same company and
I get the same message.
Can anybody explain me what wrong. I have downloaded the code from
http://www.servlets.com/soapbox/filters.html.
This is the method which throws an error (I think):
public static String[] botHosts = {"inktomi.com", "inktomisearch.com",
"googlebot.com", "linuxtoday.com.au"};
public static boolean isBot(HttpServletRequest request, Clickstream stream)
{
String requestURI = request.getRequestURI();
// if it requested robots.txt, it's a bot
if (requestURI.indexOf("robots.txt") >= 0)
{
return true;
}
// it requested a RSS feed from our backend, it's a bot
if (requestURI.indexOf("/backend/") >= 0)
{
return true;
}
for (int i = 0; i < botHosts.length; i++)
{
if (request.getRemoteHost().indexOf(botHosts[i]) >= 0)
{
return true;
}
}
return false;
}
and this is the error:
HTTP Status 500 - Internal Server Error
