Redirect all websites requests via SSL/HTTPS (Rrequire Private JVM + SSL certificate) Print

  • 0

The following article shows an example only of a servlet redirect (please, note that this may or may not work depending on your configuration) of how you can redirect your normal http traffic to https:// traffic if you have already private SSL and using our Private JVM tool. 

For more information on our SSL certificates please, check https://www.mochahost.com/ssl_certificates.php

Please, note that this solution will NOT work on our Shared Tomcat implementation or if you do not have private SSL certificate.

Step 1: Write a filter to redirect from http to https

Example for such filter is listed below:

package domain.com.servlet;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class HTTPSFilter implements Filter {
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws java.io.IOException, ServletException {

HttpServletRequest req = (HttpServletRequest) request;
HttpServletResponse res = (HttpServletResponse) response;

String uri = req.getRequestURI();
String getProtocol = req.getScheme();
String getDomain = req.getServerName();
String getPort = Integer.toString(req.getServerPort());

if (getProtocol.toLowerCase().equals("http")) {
// Set response content type
response.setContentType("text/html");
// New location to be redirected
String httpsPath = "https" + "://" + getDomain + ":" + getPort
+ uri;
String site = new String(httpsPath);
res.setStatus(HttpServletResponse.SC_MOVED_TEMPORARILY);
res.setHeader("Location", site);
}
// Pass request back down the filter chain
chain.doFilter(req, res);
}
@Override
public void init(FilterConfig arg0) throws ServletException {
// TODO Auto-generated method stub
}
@Override
public void destroy() {
// TODO Auto-generated method stub
}
}

Step 2: Compile above filter and create the following entries in your web.xml

<!-- HTTPS Redirect -->
<filter>
<filter-name>HTTPS</filter-name>
<filter-class>domain.com.servlet.HTTPSFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>HTTPS</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
