Description Boris Hamanov CLA 2011-04-15 15:55:40 EDT 
Build Identifier: 7.3.1.v20110307

The international form of my sub domain name is like this: XN--80AHAIUUGL4G

It is properly setup in my provider and resolves. That is tested.

My top-level domain name is citadelait.com so I wrote in jetty virtual hosts: XN--80AHAIUUGL4G.citadelait.com

However, it does not work, when I try to access my web page I am redirected to my normal web site www.citadelait.com (This is because I have setup MovedContextHandler that handles all virtual hosts that do not match the default and redirects to www.citadelait.com)

See in my default context below:

> poddruvka.citadelait.com WORKS
> www.citadelait.com WORKS
> XN--80AHAIUUGL4G.citadelait.com DOES NOT work

This paper here: http://wiki.eclipse.org/Jetty/Howto/Configure_Virtual_Hosts says it should (Although the example is for the main domain, but there should not be any difference) Here is an example of IDN sub domain that works perfectly: http://xn--2z1b67o3qg.blogspot.com/

<?xml version="1.0"  encoding="UTF-8"?>
<!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure//EN" "http://jetty.eclipse.org/configure.dtd">

<Configure class="org.eclipse.jetty.servlet.ServletContextHandler">
  <Set name="contextPath">/</Set>
  <Set name="resourceBase"><SystemProperty name="jetty.home" default="."/>/webroot/</Set>
  <Set name="virtualHosts">
    <Array type="java.lang.String">
      <Item>www.citadelait.com</Item>
      <Item>XN--80AHAIUUGL4G.citadelait.com</Item>
      <Item>poddruvka.citadelait.com</Item>
    </Array>
  </Set>

Reproducible: Always

Steps to Reproduce:
1.Enter IDN name in virtual hosts context configuration
2.Try to access the host with the IDN name
3.Jetty does not recognize it

Boris, 

Have a read of https://bugs.eclipse.org/bugs/show_bug.cgi?id=319057

How are you trying to access the url? If in the browser, then you should type in the non-encoded form of the name. In your case that is:

http://поддръжка.citadelait.com

If that's what you're doing, can you capture a tcpdump/wireshark trace of the http dialog with jetty, and ensure you have DEBUG enabled and send the relevant sections of the jetty log file.

thanks
Jan

I read https://bugs.eclipse.org/bugs/show_bug.cgi?id=319057 It seems that I do everything correctly.
Indeed, it would be nicer to use the original form of the url. Thanks for that guys, I will use it when it is ready.

I tried using both 

http://поддръжка.citadelait.com and http://xn--80ahaiuugl4g.citadelait.com NOTHING works

This is the log from fidler2

This is the jetty debug log about that particular request. I will atach the complete session log

Comment 4 Boris Hamanov CLA 2011-04-16 06:38:20 EDT 
Additional note: I have removed UTF-8 encoding from my default.xml (default context) I added that in the hope that the unicode coded form (поддръжка) will work. It did not, so I reverted it back to ISO-8859-1. Anyway why Jetty fails to handle plain ANSI domain name is beyond me. Maybe the "--" part bothers it somehow? Can you reproduce that on your side? Does the top level IDN domain name work in this Jetty version?
Comment 5 Greg Wilkins CLA 2011-05-10 04:03:54 EDT 
I just added your domain to the ManyContexts example and used telnet to send the following request:

GET http://xn--80ahaiuugl4g.citadelait.com/context/foobar  HTTP/1.1
Accept: text/html, application/xhtml+xml, */*
Accept-Language: en-US,bg-BG;q=0.5
User-Agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64;
Trident/5.0)
Accept-Encoding: gzip, deflate
Connection: Keep-Alive
Host: xn--80ahaiuugl4g.citadelait.com



to which I got the response:


HTTP/1.1 200 OK
Content-Type: text/html;charset=UTF-8
Content-Length: 188
Server: Jetty(7.x.y-SNAPSHOT)

<h1>A Virtual Context</h1>
<a href='/'>root context</a><br/><a href='http://127.0.0.1:8080/context'>normal context</a><br/><a href='http://127.0.0.2:8080/context'>virtual context</a><br/>


So the virtual host mechanism does look to be working.

Can you look at ManyContexts example and convert that into a test that fails for you. Then reopen this issue with that test attached.
