I don't know if Mangolia has any utilities for this, but we created our utility
function for external links which gets the scheme, server name and server port
from the HttpServletRequest via MgnlContext:
----
public String makeExternalLink(String link) {
if (LinkUtil.isExternalLinkOrAnchor(link)) {
return link;
} else {
if (!link.startsWith("/")) {
link = "/" + link;
}
return getExternalPrefix() + link;
}
}
private String getExternalPrefix() {
HttpServletRequest request = MgnlContext.getWebContext().getRequest();
String scheme = request.getScheme();
String prefix = request.getScheme() + "://" + request.getServerName();
int port = request.getServerPort();
if (!((scheme.equalsIgnoreCase("http") && port == 80) ||
(scheme.equalsIgnoreCase("https") && port == 443))) {
prefix = prefix + ":" + port;
}
return prefix;
}
