Class SecuredRemoteAddressRequestWrapperFactory

java.lang.Object

org.apache.wicket.protocol.http.servlet.AbstractRequestWrapperFactory

org.apache.wicket.protocol.http.servlet.SecuredRemoteAddressRequestWrapperFactory

public class SecuredRemoteAddressRequestWrapperFactory
extends AbstractRequestWrapperFactory

Sets ServletRequest.isSecure() to true if ServletRequest.getRemoteAddr() matches one of the securedRemoteAddresses of this filter.

This filter is often used in combination with XForwardedRequestWrapperFactory to get the remote address of the client even if the request goes through load balancers (e.g. F5 Big IP, Nortel Alteon) or proxies (e.g. Apache mod_proxy_http)

Configuration parameters:

XForwardedFilter property	Description	Format	Default value
securedRemoteAddresses	IP addresses for which ServletRequest.isSecure() must return true	Comma delimited list of regular expressions (in the syntax supported by the Pattern library)	Class A, B and C private network IP address blocks : 10\.\d{1,3}\.\d{1,3}\.\d{1,3}, 192\.168\.\d{1,3}\.\d{1,3}, 172\\.(?:1[6-9]|2\\d|3[0-1]).\\d{1,3}.\\d{1,3}, 169\.254\.\d{1,3}\.\d{1,3}, 127\.\d{1,3}\.\d{1,3}\.\d{1,3}

Note : the default configuration is can usually be used as internal servers are often trusted.

Sample with secured remote addresses limited to 192.168.0.10 and 192.168.0.11

SecuredRemoteAddressFilter configuration sample :

 <filter>
    <filter-name>SecuredRemoteAddressFilter</filter-name>
    <filter-class>fr.xebia.servlet.filter.SecuredRemoteAddressFilter</filter-class>
    <init-param>
       <param-name>securedRemoteAddresses</param-name><param-value>192\.168\.0\.10, 192\.168\.0\.11</param-value>
    </init-param>
 </filter>
 
 <filter-mapping>
    <filter-name>SecuredRemoteAddressFilter</filter-name>
    <url-pattern>/*</url-pattern>
    <dispatcher>REQUEST</dispatcher>
 </filter-mapping>

A request with ServletRequest.getRemoteAddr() = 192.168.0.10 or 192.168.0.11 will be seen as ServletRequest.isSecure() == true even if ServletRequest.getScheme() == "http".
