What happens when you try to redirect to an external URL? How are you trying to do it? Show us some code. – Politicking

@Matt: I'll bet that he was fiddling with navigation cases and outcome values. That's indeed not possible then. For internal pages a <redirect/> or outcome?faces-redirect=true works fine. – Therapeutic

Either just mention the URL directly in <a> or <h:outputLink>.

<a href="https://stackoverflow.com">Go to this site!</a>
<!-- or -->
<h:outputLink value="https://stackoverflow.com">Go to this site!</h:outputLink>

Or, if you need to to invoke a bean action using <h:commandLink> like below,

<h:form>
    <h:commandLink value="Go to this site!" action="#{bean.redirect}" />
</h:form>

then use ExternalContext#redirect() in action method.

public void redirect() throws IOException {
    // ...

    ExternalContext externalContext = FacesContext.getCurrentInstance().getExternalContext();
    externalContext.redirect("https://stackoverflow.com");
}

Note that you don't need to catch that IOException, the server will deal with it. Also note the importance of including the scheme (https:// or http:// or //) in the URL, otherwise it will be interpreted relative to the current domain.
