I would like to implement OpenAuth in a Windows application. I am currently embedding a browser inside the application, but this solution sucks.
Is there a way to do this using raw APIs?
Since you mention a browser, I assume you are interested in implementing an OAuth client, not a provider. You can try the Scribe library. It's written in Java, has client implementations for several different providers and is pretty easy to extend for new providers.

I am trying to see if I can create a simple website, like a blog, using only Ruby. No Rails or a database or outside web servers. I plan to store the data in a file for persistence.
I wanted to use TCPServer, CGI, and Net::HTTP.
Is there an easier way I can use?
There are a lot of moving parts when designing a website.
Depending on the purpose of the exercise, you might want to consider using a very simple web framework like Camping, Sinatra, or Ramaze. This is probably the best solution if you're trying to get a top level understanding of web programming because it only has exactly what you need (Camping is less than 4k!) and handles stuff like routing.
Building a web server is more an exercise in HTTP parsing. You might want to omit the framework and try to build something on top of Rake (an API for lots of popular web servers) and a simple web server like Webrick or Thin.
You could also try Espresso
It is easy to learn and fast to run.
And offers all the liberty you need for creation process.
Also it has no hidden "fees", everything is transparent.
I don't want someone keep F5 my site or using some tool to request the page frequently.
That is to say, prevent an Action or the Controller to be invoked frequently by one client.
How can I implement this? Is there any package I can use? just like AntiXSS library.
Most of these features are going to be found in the IIS manager. Something like Dynamic IP Restrictions should help. Read through Microsoft's Best Practices for Preventing DoS/Denial of Service Attacks, this provides a good list of thing to do.
Also according to this video, Cloud Flare is able to prevent these attacks with their free service.
I want to consume a file which is wsdl with VB6 , anyone can help me? Or how can I convert wsdl to proxy class ?
You can look at either Microsoft's SOAP Toolkit or PocketSOAP. Might be best to look at both, but don't despair over the learning curve. Both offer simple approaches for simple situations as well as complex solutions for more complex ones.
First, you have a problem with terminology: you do not want to consume the file. The file is a description of a web service. It is the web service that you want to consume. The WSDL gives you all the information you need to consume it.
There are methods to consume a web service in VB6. In the same way you shouldn't be using VB6, you shouldn't be using any of these methods.
You should use VB.NET to create a small COM component. This component will consume the service by using "Add Service Reference" to create proxy classes. You will be able to use modern tools and techniques to develop and debug this component.
You can then consume the COM component from VB6, just like any other COM component.
Basicly you can use the SOAP moniker like this
Set oProxy = GetObject("soap:wsdl=http://server/folder/service.wsdl")
oProxy.Method "Param1"

Without reinventing the wheel, what I can use to manage user sessions in a web application and being able to respond with JSON to ajax requests?
Is there some framework (made for example with Indy components or something like this)?
Note for bounty:
in practice it is enough for me to have a reply with a clear example of a server application that serves json. Somehow a Delphi example of the php example mentioned HERE. (without the DB part, I want to see the basics of what does it mean to send JSON. I have basic knowledge of TIdHTTPServer.)
You can take a look at our Synopse SQLite3 Framework, which was just updated to version 1.11.
It serves the data in pure JSON, ready to be used in any AJAX application.
You can also easily create Services, more precisely Client-Server JSON RESTful Services. In this case, you can even not use SQLite3 for your data storage.
This framework is pure Open Source, compiles/run/is tested for Delphi 6 up to XE, is Unicode ready for all versions of Delphi (it uses UTF-8 internally).
By using this framework, you could be able to create easily also Delphi clients, using JSON data from the same server.
There is no internal User session handling yet. Because there are several way of implementing them, and, since our framework is RESTful, it's therefore stateless: no session is needed.
If you need it, I could easily add HTTP sessions using Cookies. What about the User authentication you are expecting?
Maybe this can help you:

DelphiMVCFramework does this
Some notable features:
RESTful (RMM Level 3) compliant
Can be used in load balanced environment using Redis (http://Redis.io) [dev]
Fancy URL with parameter mappings
Specialied renders to generate text, html, JSON
Powerful mapper to map json to objects and datasets to objects
Can be packaged as stand alone server, apache module (XE6, XE7, XE8) and
ISAPI dll
Integrated RESTClient Works with XE3, XE4, XE5, XE6, XE7
and XE8 Completely unit tested
There is a sample for each functionlities
There is a complete set of trainings about it, but the
samples are included in the project Experimental support for IOCP
[dev]
Server side generated pages using eLua (Embedded Lua) [removed soon]
Specific trainings are available (ask me for a date and a place)
Messaging extension using STOMP (beta)
Community driven (Facebook group https://www.facebook.com/groups/delphimvcframework)
Simple and documented
There are books that talk about the framework
Project web site: https://github.com/danieleteti/delphimvcframework
N.B. I'm the main developer
I would suggest Delphi on Rails, it is an open source REST/MVC/StateLess web framework.
http://code.google.com/p/delphionrails/
It use:
superobject JSON parser
UIB/Firebird JSON driver
Cairo for SVG, PDF, PNG rendering
LUA for scripting/template ...
It is able to serialize automatically Delphi data structures to JSON using the new RTTI introduced in Delphi 2010 & XE.
I would recommend Super Object Toolkit.
http://www.progdigy.com
Example Code:
procedure Share(ARequestInfo: TIdHTTPRequestInfo)
var
ReturnObject: ISuperObject;
begin
ReturnObject := SO();
ReturnObject.B['success'] := false;
AResponseInfo.ContentType := 'application/json';
AResponseInfo.ContentText := ReturnObject.AsJSon();
end;
Daraja HTTP Framework, which uses Indy internally and adds a high level API for "web application contexts" and request mappings, loosely inspired by the Servlet API.
If you already have experience with TIdHTTPServer, you can directly access and adjust the server component according to your needs.
For JSON, you may use the built-in JSON support in newer Delphi versions or a third-party library (e.g. JsonDataObjects).
Disclaimer: I am the developer of the framework
I would like to create a web page which would allow multiple users to work together on a page, Imagine a web based editor that allowed to users to change the documents as an example of this type of feature.
How would more experienced programmers go about implementing this as i really cant seem to formulate any way to even begin going about this task. Would there be any programming librarys that make implementing this feature easier or is it just too complex to even think about?
I am creating this webapp primarily using GWT and SmartGWT if that helps.
Thanks for any input you may have.
There is indeed a cometd-like library for gwt - http://code.google.com/p/gwteventservice/
Wiki:
In web development, Comet is a neologism to describe a web application model in which a long-held HTTP request allows a web server to push data to a browser, without the browser explicitly requesting it. Comet is an umbrella term for multiple techniques for achieving this interaction. All these methods rely on features included by default in browsers, such as JavaScript, rather than on non-default plugins.
In practice:
In normal way client can receive resources by request->responce. It is no possible to send data directly to client without request. With comet you can hold realtime connection between client and server and exchange data in realtime.
Check out: docs.google.com. They are using comet.
Etherpad.com is a service that used to do this. It has been since bought by Google, and the code released as open-source. You can see several links on the etherpad.com page for the source download and related information.
