How to enable ip lookups - resolve hosts on Wildfly

[susnet]

On JBoss 7.1.1 there was an attribute: enable-lookups="true" that could be set on the host element in standalone.xml that enabled ip host lookup. In earlier versions of JBoss I think the attribute was called resolve hosts.

How is this done on Wildfly 8.1.0?

Do you mean the enable-lookups attribute on the connector element in previous versions:

<connector name="https"

    scheme="https"

    protocol="HTTP/1.1"

    socket-binding="https"

    enable-lookups="false"

If yes, then in WildFly 8 the Undertow subsystem is where those connectors get configured. Someone from the Undertow team might be able to help you on that.

Yes, that's what I mean. I hope someone from the Undertow team could answer. I read the documentation but did not find anything.

Hey, in undertow this is enabled by default and we don't have flag to control this behavior yet.

this is the current impl for this method undertow/servlet/src/main/java/io/undertow/servlet/spec/HttpServletRequestImpl.java at master · undertow-io/undertow · G…

I talked bit more with guys and this should actually be configurable as we have special handler that makes does reverse dns lookup

but it is not configured by default or in any case for that matter.

handler is io.undertow.server.handlers.PeerNameResolvingHandler and should be added to lifecycle of the request.

until we have it properly implemented as configuration option, only way to do it is by creating ServletExtension and adding it there see http://undertow.io/documentation/servlet/servlet-extensions.html for more info on that.
