    Assuming that you'd like to redirect to some.xhtml which is placed in web root folder:

    1. You can just continue using plain HTML.

       <a href="#{request.contextPath}/some.xhtml">go to some page</a>
      

      For conditional rendering, just wrap it in an <ui:fragment>.


    2. Or use <h:link> with implicit navigation.

       <h:link outcome="/some" value="go to some page" />
      

      Note: no need to prepend context path nor to include FacesServlet mapping.


    3. Or use <h:commandLink> with ?faces-redirect=true.

       <h:commandLink action="/some?faces-redirect=true" value="go to some page" />
      

      Note: no need to prepend context path nor to include FacesServlet mapping.


    4. Or use <h:outputLink>, but you need to specify context path.

       <h:outputLink value="#{request.contextPath}/some.xhtml" value="go to some page" />
      

    Redirecting to an external URL is already answered in this duplicate: Redirect to external URL in JSF.
