Ok...
I'm writing a ASP.Net MVC 2 application, and one of the requirements is that I log the headers on the requests we receive, and also on the responses we send...
My approach to do this has been to create a controller that overrides OnActionExecuting and OnActionExecuted, and then create our actual "live" controllers by inheriting from this rather than from the usual base class. This way, I basically get the logging functionality for free.
While this approach works fine for handling the requests, responses seem to be another matter. I am getting an error telling me that the Headers property of the HTTPResponseBase class requires IIS to be using the Integrated Pipeline. I therefore have two questions.
Question 1.
Can anyone suggest a means to get the headers through a means other than HTTPResponseBase.Headers? I have considered for example simply parsing the entire resposne and getting them that way myself, but I was hoping someone might have a better way...
Question 2.
What is this Integrated Pipeline? What does it do? How do I enable it?
Cheers in anticipation...
Martin.
In response to Question 2:
Integrated Pipeline is a new feature in IIS 7 and higher, you can change the application pool in IIS7 to use this new pipeline.

I have a SOAP endpoint and will be having more than 1000 request messages which have different values for the request parameters but same operation of SOAP Message. I want to execute them in a sequence if the previous request that got triggered was 200 OK?
Is there any way to do this without JAVA program? Is there any client that will help me?
I assume you already have some sort of loop in your test case that reads your variable properties from a file or perhaps Excel and feeds them into your SOAP request. Ready API/soapUI Pro gives you this functionality, but for open source soapUI you'll have to write your own Groovy test steps.
Then, you can use a soapUI Compliance, Status and Standards assertion to check you've received a valid or invalid HTTP status code and react accordingly.

After re-reading the question, it seems to me you're not yet using SoapUI, though it has been tagged as a SoapUI question. It happens quite a lot on here where people are askign general SOAP questions, but tag SoapUI. BTW, Craig's answer should be accepted if you are using SoapUI.
In terms of options, you have lots....
Code. You can use Python, C#, Java, Javascript, etc. etc. to create a program that will call your endpoint. Any programming language will have the libraries to call web services. So, if you do know a language, you could use that.
SoapUI. There is a free version, which will allow you to call web services. In your question, you want to call the same service over and over with different parameters. In testing speak, this is a data-driven test. These can be achieved in the free SoapUI, but it is a fiddle. However, the full-licensed version offers data-driven tests out of the box. I use these all the time. Very easy to set-up. If you use SoapUI, then Craig's answer about using Assertions would stop the test if you got a status code other than a 200.
Postman. this is another free tool, which I have used a little. I haven't tried data-driven tests, but I'm sure the docs will tell you if they're supported. If you try Postman, then you ought to look at Danny Dainton's excellent tutorial on GitHub
JMeter. Another free tool. This is primarily used for performance and load testing, but would still meet your needs.
I know the question is about solving the problem probably by different approach but let me specify in details what I want to ask and how much I understand about it.
We have two mvc approach used in ATG(or many other framework) pull based and push based.
As I understand it formhandlers and droplet both are playing the part of controller in different need, repositories are our model and jsps are providing views..
And if i am right till this point then what purpose the servlet chain is solving?How it fits into this picture of MVC?
Please If possible explain with the help of flow diagram from request to response (end to end).
Thanks a lot in advance to experts.
Please help.I could not find this kind of explanation anywhere.
The first thing to remember with ATG is that it is an old platform. So when trying to understand the different mechanisms through an MVC lens, remember that nothing was designed with MVC in mind-the platform predates widespread knowledge and acceptance of the MVC pattern in web development.
Droplets are a generalized mechanism for invoking Java code from a JSP (and previously, JHTML) template. The closest analogue in J2EE-land would be tag libraries. So you can use them to accomplish many different tasks. You can also use them as a poor man's MVC controller. This is done by coding a custom droplet class dedicated to handling the business logic of your page, and setting relevant page state as request parameters. Then you invoke the droplet as the first step in your JSP page. This is not very different from J2EE model 2 with the odd quirk that first your compiled JSP begins executing, then invokes your "controller" code and then resumes with processing the "view."
Form handlers, as the name indicates, are designed for processing form submissions. These are executed by a link in the servlet pipeline (DAFDropletEventServlet), before the page which was posted to begins rendering. Typical usage with form handlers is that they will send a redirect after executing, and cancel rendering of the page, which will abort any further processing by the servlet pipeline. Form handlers are the closest thing to a "controller" ATG provides. But they are awful for handling GET requests and result in some very unfortunate URLs when used for this purpose.
Why did they create two different mechanisms? Why have they not subsequently introduced an updated MVC model as part of the platform? These questions I cannot answer.
ATG, at the page rendering level, is not MVC. Don't look at it as MVC. ATG, at its core, is an extension of the basic Servlets API.
Forms and form-processing, with the successUrl and errorUrl is kind-of MVC. Droplets certainly are not.
It is perfectly acceptable in an ATG application to be fetching data as the page is rendering (i.e. Droplets)
Alright, so a better title here may have been "Progressive Enhancement with REST in CakePHP", but at least now I'll know you didn't read the question if your answer just refers to the difference between the two ;)
I'm pretty familiar with REST and how to integrate it with CakePHP, but I'm not 100% on board with how to still maintain a conventionally functioning website. Using Router::mapResources sounds like a great idea, but this creates a problem with maintaining the "gracefully degradation" version of the site, because both POST requests to /resource/ AND GET requests for /resource/add will route to the same action (add). Clearly I'll want this action to return a JSON object if they're using the REST api, but if they're using the degraded version of the site (no JS perhaps), it should be a add form, right?
What's the best way to deal with this. Do you route your REST requests to other action names using Router::resourceMap()? Do you do that crazy hack I saw to have the /api/ prefix part of the resourceMap so you can use api_action functions? Do you have the actions handle both REST and conventional requests via checking isAjax()? If so, how do you ensure that you can rely on the browser to properly support the other two request types?
I've searched around quite a bit but haven't found anything about how to keep conventional requests available in Cake along side REST, so if anyone has any advice or experience, I'd love to hear it!
CakePHP uses extension routing as well, via Router::parseExtension() so;
/test/action will render views/test/action.ctp
/test/action.html also
/test/action.json will render views/test/json/action.ctp
/test/action.xml will render views/test/xml/action.ctp
If all views are designed to handle the same data as set by your controller, you'll be able to show a regular HTML form and handle the posted data the same way as you'd handle the AJAX request.
You'll probably might have to add checks if any data is posted/submitted inside the /add, /edit, /delete actions to prevent items being deleted without a form being posted (haven't tested that though, it might be that cake blocks these urls if mapresources is set for the controller)

I'd like to use Gatling for REST performance and scalability web service testing. I'm currently using JMeter for this as I wasn't aware of gatling when I started this project. Gatling would integrate better and would be better for the project a number of reasons.
I'd like to ask one main question:
Obviously, there's a lot of overhead in configuring Gatling with the correct web service information. I've already done this in JMeter and I'm not keen to do it again. For one of the sub-projects, we have a WADL but we have no such thing for the other. Is it possible, out of the box, to import:
a. JMeter test plans and
b. WADL documents
into Gatling?
I've looked through the docs but unfortunately I can't find anything that references these.
No, Gatling has neither.
Building a jmx converter is something we might investigate in 2013, as you're not the first one to ask for it. At this point, I'm a bit skeptical, as the logic and the configuration of the 2 JMeter and Gatling are quite different, so the features and the way to use them don't map 1:1.
The easiest way to work with REST APIs is to use the recorder, so you'd dump request bodies as template and then inject data into them. See http://gatling.io/docs/2.1.6/http/http_request.html#request-body
If you work with JSON, you can use our JsonPath (or standard regex) checks in order to make assertions on the response body, or even capture data. See http://gatling.io/docs/2.1.6/http/http_check.html#defining-the-check-type
Using HttpSampler with Raw Post body And last 2.8 version is the right way to test Webservices.
Is it the way you are doing it ?
Upcoming 2.9 has new performance improvements related to memory and cpu consumed by Post Processors.
Regarding a, I don't think so.
On an asp.net mvc 2 app, I'm using Unity 2.0 interception app for various types of logging where every log entry requires the id of the current user.
Currently I'm passing the User object as an argument to service and repository methods. The only reason I'm doing this is so that it's available on MethodInvocation.Argumants for the intercepted method. Ideally, I'd like to supply the interceptor with a User object somehow. This doesn't seem to be possible. Does anybody know if it is or if any other .net AOP tool provides this? I also remember this being a problem several years ago on a project using Spring/Java so I guess it is a common problem that hopefully someone has solved?
I worked it out.
To handle the intercepted calls, you have to supply an implementation of ICallHandler.
Add a User parameter to the implementation's constructor.
