RE: Understanding Restlet's Threading Model?
Hi all, Rob is right, the threading strategy depends on the actual server used (Grizzly, Jetty, Simple or the NRE internal one). In general there is a pool of worker threads. This pool has a configurable size so you can generally limit the maximum number of concurrent threads. See this page for configuration details: http://www.restlet.org/documentation/1.1/connectors#jetty For Jetty here is the list of parameters available: http://www.restlet.org/documentation/1.1/ext/com/noelios/restlet/ext/jetty/J ettyServerHelper Now, be aware that web browser generally serialize the request to a single target server/domain at least limit the number of concurrent requests sent. If you really want to test the concurrent behavior of your Restlet application, you should instead use a proper load tester. Here is a benchmark that was done by Thierry on 1.0 connectors: http://www.restlet.org/documentation/1.0/benchmark Best regards, Jerome -Message d'origine- De : Rob Heittman [mailto:[EMAIL PROTECTED] Envoyé : lundi 3 mars 2008 22:45 À : discuss@restlet.tigris.org Objet : Re: Understanding Restlet's Threading Model?

snapshot releases and the maven.restlet.org repository
Hi I'm just starting to build against the 1.1-SNAPSHOT code so as to get in sync with the restlet release schedule, and I have a couple of questions 1. how often does the snapshot get updated? 2. is it possible to tweak the settings on the site so that the expires: header on all the -SNAPSHOT artifacts have a very short lifespan (a few hours, maybe). We build behind a proxy server, see, and it can pick up dated artifacts if I'm not careful -steve
Re: snapshot releases and the maven.restlet.org repository
Hello Steve, 1. how often does the snapshot get updated? The public repository (http://maven.restlet.org) is updated on 1st and 15th of each month, except in cases of bug fixing. There is also a private repository which is refreshed with new releases at the moment they are made which mans that the snapshots are refreshed on a daily frequency. You can have more details about both private and public repositories by having a look at this page (http://www.restlet.org/downloads/maven). 2. is it possible to tweak the settings on the site so that the expires: header on all the -SNAPSHOT artifacts have a very short lifespan (a few hours, maybe). At this time, the expiration time is set to 10 minutes. best regards, Thierry Boileau On Tue, Mar 4, 2008 at 12:56 PM, Steve Loughran [EMAIL PROTECTED] wrote: Hi I'm just starting to build against the 1.1-SNAPSHOT code so as to get in sync with the restlet release schedule, and I have a couple of questions 1. how often does the snapshot get updated? 2. is it possible to tweak the settings on the site so that the expires: header on all the -SNAPSHOT artifacts have a very short lifespan (a few hours, maybe).

On Tue, Mar 4, 2008 at 1:52 AM, Jerome Louvel [EMAIL PROTECTED] wrote: [...] Now, be aware that web browser generally serialize the request to a single target server/domain at least limit the number of concurrent requests sent. Indeed. From http://www.w3.org/Protocols/rfc2616/rfc2616-sec8.html#sec8.1.4 : Clients that use persistent connections SHOULD limit the number of simultaneous connections that they maintain to a given server. A single-user client SHOULD NOT maintain more than 2 connections with any server or proxy. A proxy SHOULD use up to 2*N connections to another server or proxy, where N is the number of simultaneously active users. These guidelines are intended to improve HTTP response times and avoid congestion. Web browsers are pretty good about following that rule. ObHack: If you want to up that concurrency for your own site, one trick is to use multiple names for the same underlying set of servers. I.e., if you have lots of images on a page, spreading out the requests across host1.example.com, host2.example.com, allows the browsers to issue more simultaneous requests. Have fun, John
Usage of the latest spring snapshot SpringApplication
Hi there,
I have been using the SpringApplication and extended it to look like
public class TestRestApplication extends SpringApplication {
public static GeneralDao dao;
public TestRestApplication(Component comp) {
super(comp);
}
public void setGeneralDao(GeneralDao dao) {
this.dao = dao;
}
}
And registered that in the Spring context.xml using
bean id=restApplication scope=singleton
class=test.TestApplication
constructor-arg ref=restComponent /
property name=root
bean class=org.restlet.ext.spring.SpringRouter
constructor-arg ref=restApplication /
property name=attachments
map
entry key=/v1/issue/new/
value=test.NewIssueResource/
/map
/property
/bean
/property
property name=generalDao ref=generalDao/
/bean
but now the super constructor seems to be private. How is this class now
supposed to be used?
Thanks for any hints
/peter
RE: Usage of the latest spring snapshot SpringApplication
Hi Peter,
Thanks for reporting this bug. It is now fixed in SVN trunk.
If you can't use the trunk, just invoke the constructor with a context taken
from your component.
public TestRestApplication(Component comp) {
super(comp.getContext());
}
Best regards,
Jerome

Authentication Header
Hi, On server side, I am trying to set a header which will look like this ABC realm=, challenge-container=salkfadfo823w9283oinfskefn2398wenfdsk; Can anyone tell me how can I achieve that? Here I want to mention that, I dont/can't change the challenge format. So, don't ask me to do that :), also i want the challenge to go on server side as WWW-Authenticate header with a status code 201. Thanks in advance. Regards, Jahid
Re: Understanding Restlet's Threading Model?
Hi Rob, Thank you for your reply. I believe the connector I'm using is the Simple one, since I've put com.noelios.restlet.ext.simple as a dependency in my Maven project and I don't believe I'm including any other connectors on the class path. Is there a good way to do a sanity check on this? Also, any good rules of thumb to use when evaluating the different connectors? (In my situation, I actually have full control over the clients that will be hitting me, so maybe that's an important factor?) Thanks again to everyone for the help!

I'm not sure (I haven't tried it yet myself), but I think that you create a ChallengeRequest object and set it in the Response. In 1.1- M2, it seems like one way to do this would be by extending Guard and overriding the challenge method. If you are using the reference engine implementation (NRE), you could also implement com.noelios.restlet.authentication.AuthenticationHelper and register your implementation using Engine#registerAuthentication. N.b.: like I said before, I haven't tried any of this myself yet. I just happen to be looking into implementing a custom authentication scheme today. Rhett

setting a status description never shows up in the response?
We are using 1.0.8 and setting a status description in a response. If we use the jetty or the servlet connector, our description is not passed along, but the default is. For example, if we change the 404 description in the response status, it still says Not Found as the decription. But, if we use the Simple connector, it works as expected. We've looked through the list, but haven't seen any issues related lately ( there was a post about the servlet connector back in 2006 v1.0.5 ). Is there a known issue ( we tried 1.1M2 as well, same results )?
Authentication: multiple challenges?
Hi, According to RFC2616 section 14.47, it should be possible to have multiple challenges in a WWW-Authenticate header. I can't see a way to achieve that with Restlet. Is there a way? Context: I'm trying to protect a collection of resources with both HTTP Basic and a custom token-based authentication scheme. If it's not possible to have multiple challenges, I'll just challenge with Basic and then accept either form. Thanks, Rhett

Reference and reference list
I am looking for reference and reference list guidance, examples ( I think).
At the first level of my service my URI pattern is simply AT the root my
service is simply /{type};
In the root of my service I just started creating I would like to return a
list of links to all available types. I would like the list to have a title
and each link to have some descriptive label. I will need to do it in html
and xml, but lets concentrate on html. Before starting to craft my HTML and
XML by hand I looked around and looks to me ReferenceList is a good
candidate to help.
So in my Resource.represent I do something like:
ReferenceList rl = new ReferenceList();
for (int i = 0; i supportedTypes.length; i++) {
Reference url = new Reference(getRequest().getRootRef());
url.addSegment(supportedTypes[i]);
rl.add(url);
}
return rl.getWebRepresentation();
Any hints, example or doc pointes would be highly appreciated. I tried, but
I think I do not understand the concepts I am dealing with.
I would like to make it more informative, with the page title (instead of
List of references), labels, the text for each URI, instead of dry URI.
Here is what I get now:
List of references
http://localhost:9080/myrest/Type1
http://localhost:9080/myrest/Type2
...
I would like to get at least:
List of links for lists of items of a specific type
Type1
Type2
...
With URIs in the source.
