Hi,

has anyone implemented digest access authentication before? I am in  
the process of implementing this feature and any hints would be highly  
appreciated.

with kind regards
Björn

Hi,

Ya that will work. Although you might want to det the description.

response.setText("Not Found");

But thats not really that important.

Subject: [Simpleweb-Support] Proper way to send a 404

Hi,

its a simple question. How to send a proper error code to the client? Just the status code, no body and drop the connection afterwards.

response.set("Server", "HelloWorld/1.0 (Simple 4.0)"); response.setDate("Date", System.currentTimeMillis()); response.set("Content-Length", 0); response.setCode(404); response.commit(); response.close();

This way?

with kind regards,
Björn

Hi,

The @Attribute on class Item is causing the problem the "id" is stripped for the key to the map. So its considered not existing for the Item class. Remove the String field "id" annotated with @Attribute and it will work.

Hi,

Ya, the whole idea behind the new implementation is that every connection can have something like.

public clas MyServer implemenets Server {

  public MyServer(Server delegate, SocketAddress address) {
    this.delegte = delegate;
    this.address = address;
  }

  public void process(Socket socket) throws Exception {
    socket.getAttributes("socket.source", address);
    delegate.process(socket); 
  } 
}

Hope this makes sense.

Cool, will look into this...

Yeah, for most requests that will be the way I intend to resolve it..  
the problem comes with wanting to server up sites with bigger  
flexibility. For example a site could accept multiple cnames and use  
it to separate customers... such as customer1.foo.lan and  
customer2.foo.lan... both being handled by one site that deals with  
all connections to a specific ip:port combination.

So basically, I want to be able to bind to any number of ip:port  
combinations and have virtual hosts that bind to these... most of the  
times through one or more specific hostnames, but sometimes also as a  
wildcard as described above.

Hi,

Yes there is, just implement the Server interface. Then for each connection do the following.

Server actualServer = new ProcessorServer(containerProcessor)

SocketAddress address1 = new InetSocketAddress(8080);
Server server1 = new MyServer(actualServer, address1);
Connection connection1 = new SocketConnection(server1); 

SocketAddress address2 = new InetSocketAddress(8080);
Server server2 = new MyServer(actualServer, address2);
Connection connection2 = new SocketConnection(server2); 

Alternatively you could just get the "Host" header, it will contain the virtual host. So a URL such as

http://host:9090/path

Will have a "Host" header of "host:9090". Its a requirement of HTTP/1.1. In fact it is perfectly legal to reject a request without a "Host" header.

Hi,

Is there a way to find the IP that the client connected to from the  
Request object?

For context, I have multiple Connection objects passing their requests  
to the same container... I could let each Connection object have its  
own Container object, but that would end up being purely for passing  
along the ip, so I would much rather be able to simply locate that  
information in a general container :-)

Thanks!

Hi,

Without knowing much more about this case than what is written below, the
problem seems to be more Chrome related that Simple related. While Simple
may respond differently (which would explain why Jetty works), Chrome
shouldn't just "hang" and use 100%. Please remember that Chrome is an
experimental browser, and has not been released for production use by
Google.

It would be most helpful if you could run an ethernet eavesdropper to record
all of the raw network communication between Chrome and Simple, then Chrome
and Jetty. This may allow someone here to find the difference, and narrow
down the issue. Who knows, perhaps there is an issue with Simple's HTTP
protocol. Most likely, it's a bug that the Google developpers would love to
hear about.

Hello, All,

I've used Simple (v.4.1.13) for my application as an https engine inside
Restlet framework. Out application suggest RESTful API, and such API used
from browser-based web-application clients, and from desktop clients. 

Recently I've noticed what accessing app from Google Chrome (v.2.0.172.31)
from time to time (not each request, but very often) causing it to hang,
consuming 100% of CPU. I've made some checks, and it seems it actual just
for Chrome+Simple pair.

 1. Other https engine, (Jetty) does not shows such behavior
 2. FF or Safari does not shows such behavior.

So the most suggestion, from my point of view, is what Google Chrome
XmlHttpRequest object doing some mess, which Simple can't interoperate
correctly. I can not extract reproduceable test case for this for the
moment, but hope my explanations may give the hint about where to dig.

Ruslan.

P.S. I've tryed to debug this case, but can't understand Simple internal so
deep. Most of the time, there are 3 active threads with ActinDistributor,
spending most of the time in the ActionDistributor.distribute method. By
stepping it seems like there are channels, which are actually closed, or not
used, but Simple repeately tries to read bytes from it.

Thanks for sharing those source, they are very useful.

Okay, thanks again for your quick response. Probably you are right,
I'm not catching run time exception. I'll check all of my application
first. I'll report to you later :)

one last question for today, there a lot of ESTABLISH (not only
CLOSE_WAIT) connection to my application. Are there also something
wrong in my application?

This can be done with Repsonse.close() or OutputStream.close(). I would bet you are getting RuntimeExceptions that you are not catching, this skips your close() invocations and so you are left with a leak. Also 157 threads? This looks excessive.

Hi,

Well CLOSE_WAIT means you are not closing the connections, this is where your problem is. Ensure to close the response or output stream. This can be done with Repsonse.close() or OutputStream.close(). I would bet you are getting RuntimeExceptions that you are not catching, this skips your close() invocations and so you are left with a leak. Also 157 threads? This looks excessive.

Thx for your reply.

I've attached ThreadDumper output and ApplicationMonitor output for
you analysis. Regarding netstat, what information you would like to
know? For the start, here is general netstat you may want to know:

2584 #> netstat -an | grep 28102 | grep ESTABLISH | wc -l
   2043

2591 #> netstat -an | grep 28102 | grep CLOSE_WAIT | wc -l
   1288

2592 #> netstat -an | grep 28102 | grep TIME_WAIT | wc -l
      0

2589 #> lsof -p 26736 | grep ESTABLISHED | wc -l
   1022

28102 is my application listening port, and 26736 is my PID.

I'm looking forward for your assistance. thx :)

Hi,

I would need a thread dump and output from netstat to determine what is wrong with your application. With regard to stress tests I have tested Simple with at least 100 million requests using ApacheBench. Also I have tested with HttpClient, Faban and my own stress tester, again the tests involved millions of requests without any issues. Take a look at the following tools which can help grab the informataion.

For thread dumps:
http://svn.sourceforge.net/viewvc/simpleweb/trunk/src/test/java/org/simpleframework/http/core/ThreadDumper.java?revision=1448&view=markup

For general stats:
http://svn.sourceforge.net/viewvc/simpleweb/trunk/src/location/java/org/simpleframework/location/ApplicationMonitor.java?revision=1448&view=markup

Regards,
Niall

Thanx for your response. I already implement the asynchronous model of
HTTP response and it works magic :)

However, recently did load/stress test my application that uses
simpleframework http listener. I'm using httperf load tester. I set
load test traffic with 500 tps, and the application responded well
initially.

But after 30 minutes test, the application cannot receive more
traffic. I try to hit one traffic manually using telnet, it's
connected but not responding. I try to count established connection /
file handlers using this command:

lsof -p 26120 | wc -l
    1663

There's 1663 establish connection. Something's wrong here ..

I'm using both simple 4.1.11 and 4.1.10.

Then I search mailinglist archive, and found similar problem regarding
file handler. I try to switch back to 4.1.9, and it works well
initially, for an hour collapse again.

Any advice? Maybe there is something wrong in my application? FYI,
always closed every response object per request

Hi,

Yes its very simple. There are no restrictions on how to process
requests asynchronously. For example try this.

public void handle(final Request req, final Response resp) {
   new Thread(new Runnable() {
      public void run() {
         try {
            PrintStream out = resp.getPrintStream();
            resp.set("Content-Type", "text/html");
            out.println("Hello World!);
            out.close(); // commits and sends response
         }catch(Exception e) { 
           e.printStackTrace();
         }
      }
   }).start();
} 

For simple the closure of the Response object or the OutputStream is
what completes the response. So you can pass the response object to an
asynchronous thread without any issues. Hope this helps.

Niall

Hi,

Yes, take a look at Request.getTarget() this is the original HTTP
request URI, which is unmodified. You can also access the multiple
variables in the order thet were sent using Query.getAll().

http://www.simpleframework.org/doc/javadoc/org/simpleframework/http/Requ
estLine.html#getTarget()
http://www.simpleframework.org/doc/javadoc/org/simpleframework/http/Quer
y.html#getAll(java.lang.Object)

Subject: [Simpleweb-Support] Access to the querystring

Hi,

I have a quick question.
Is there ANY way to access the querystring as submitted by the client?
I'm using the Jack Framework which in turn uses SimpleHTTP.
The problem is that Simple swallows multiple values assigned to the same
query variable AND doesn't keep track of the order of the query
variables (which is ESSENTIAL for what I'm doing) when accessed the way
Jack currently uses:

String(request.getQuery().toString());

I'm trying to write a patch that fetches the querystring in a way that
keeps multiple variables and their order. I didn't find anything helpful
in the Javadoc, I hope someone can give me a hint.

kind regards

Jan Varwig

Hi,

Simple is LGPL (not like GPL because it permits closed source projects
and commercial use), but to be honest its developed by me alone. Not
through any business activity. So don't worry about licence issues just
assume you can use it as you please for personal or business use.

Hi All,

First off: awesome project, thanks for putting this out there. Having
played with this after discovering it though theserverside (async web

I have a question regarding the Jersey integration: as a provider, does
this make SimpleWeb GPL by default if using it?

Cheers

Hi All,

First off: awesome project, thanks for putting this out there. Having
played with this after discovering it though theserverside (async web
response), have been very impressed indeed.

I have a question regarding the Jersey integration: as a provider,
does this make SimpleWeb GPL by default if using it?

Cheers

Alex
