Subject Re: getting information about caller-url

Hi Georg,

You can get that info from the request-header 'Referer'. You can access 
it from the external context like below

ExternalContext extCtx = 
FacesContext.getCurrentInstance().getExternalContext();
String refererHeader = extCtx.getRequestHeaderMap().get("Referer");

Thanks
Mamallan
