I'm currently developing a website using ASP.NET MVC.I need this website to communicate with an external API using HTTP Post.
I'm unsure whether I should be coding this up in ASP.NET to perform the http post requet and read the response, or whether I should be coding this up in a c# class.It seems when developing a site, you have the option to chose either for many scenarios.
I'm using an ASP.NET Facebook Developers Toolkit (http://www.codeplex.com/FacebookToolkit) on an external website, and I'm also the admin of a facebook fan page for the website. Users on my website (may or may not be facebook users) create content articles.
I would like to hook up these articles to the Facebook fan page, so that, when they write the article, then ones with FB accounts can sign into FB and post on the Fan page. I'm sure they would need to be a fan first.
I need to send some parameters to an external website using the <asp:HiddenField /> controls and also at the same time, submit data to a sql server database. The part for submitting the data to the database is working, but I need to try to get the parameters from the hiddenfields to also be passed through. I thought all I had to do is create the hidden fields and in the code behind, set the values from the textboxes that the user would fill out.
My source code is below:

What am I missing? The hidden fields are losing their value before posting to the external website. I've looked everywhere to see why this won't work.
I want to develop an interactive website in ASP.Net and what I mean by interactive is that it has a back-end application to provide real-time logic (which does not follow HTTP's model of Request/Response) and eventually it is provided with dynamic *.aspx pages with an SQL Server database.
And how would the components go together (as a design and as a communication mechanism) to have a scalable application?
EDIT: Ok, the story is as you know, we all are tending to get something more vital than HTTP model, I want my back-end application to be persistent working in real-time, for example, It would have some constant-intervals to do some queries on the database.
The design as I picture it is a server (holding an ASP.Net website, the back-end application and the database), the design may get more hybrid with time. The website is the interactive interface for the users, the website needs (sometimes) intensive calculations and queries which better be handled by the back-end application, then the application delivers the website the info to be wrapped and formatted as HTML markup to be returned the user eventually.
RedirectResult is doing a HTTP Get. I want a redirect that does a Http POST
View 2 RepliesI've got an external site that's built in SharePoint 2007. the user of the site need to have an option to view the full site when accessed from a mobile device. I am thinking of just creating a button control to do this. The question is, what would be the best solution to do this?
View 1 RepliesI'm migrating an old ColdFusion site to ASP.NET. One of the pages has a form that posts to an external URL.
[Code]....
I just discovered that you can't do this in an .aspx page. Seems the page will just post to itself if you hit the submit button.What's the proper technique for achieving this in ASP.NET? There are a couple of hidden fields that pass parameters to the external URL.
I have an app which has a form that used to use AutoPostBack rigged controls (dropdowns, radiobuttons etc.) in an updatepanel, and I used to set session values on each postback. I posted the form using PostBackUrl to an external page, using a bit of javascript OnClientClick to copy my data into meaningfully named hidden fields.
Now, I've had to rewrite the AutoPostBack-ing controls so that all the cascading dropdown work and date calculation etc. is done in JavaScript, and not in C# - no more postbacks, no more updatepanel.
This means I've lost the ability to set my session values on postback. Can anyone think of a solution for setting these before I post my form? I need to set the session variables, plus post (querystrings are not an option) to the external page with the values from my form - and actually send the user to the external page, too.
What wrong with this code?

I would like to be able to receive a posted file over HTTP. All I've been finding is people attempting to save a HttpPostedFile after submitting it in a form.

I am working on a application which will accept the data in the post request.I will surely implement the data encryption to make sure that communication is secured. But my concern is, any body who knows the URL will be able to send the POST data request to my application, can I restrict the request from once specific IP address/URL.From a Request object can I find out which application/HOSTname/URL has sent this request. I looked at RefererURL but it can be populated and cannot be used. Is there any other field/properly which will tell me about the party who has sent this request.I want to make sure that I process request received from one specific URL/IP and want to ignore all others.
View 5 RepliesI want to do some processing on a attribute before returning the view. If I set the appModel.Markup returned in the HttpPost ActionResult method below to "modified" it still says "original" on the form. Why cant I modify my attribute in a HttpGet ActionResult method?

public ActionResult Index()
{
return View(new MyModel

Markup = "original"

[HttpPost]
public ActionResult Index(MyModel appModel)

I'm somewhere between a beginner and intermediate asp.net and c# user who is looking to receive a message/variable and then URL decode it. The message is being sent via HTTP post. I'm not sure exactly how to get started, and am looking for a tutorial but haven't been able to find one.

All I need is to send a http post request I pulled from fiddler.
I do not want to use HttpWebRequest class. It makes it hard to set up a request, does not allow to change host,
and when it does send it it looks nothing like the request I want. The server is very sensitive and unless I copy the request headers 100% it will return an empty page. Why can't I just type in the headers and send it that way? What would be 5 minutes of

We have some review coming up and my boss gave me a list of web page security vulnerabilities to look through and consider for our public site. I really don't understand the Get versus Post:
8Misusing HTTP POST and GET
Use POST to submit forms
Use GET to access resources
–NEVER use GET to authenticate users as it leaves a residual trace of all users in the web server access logs (not to mention web application proxy tools)
I'm trying to upload a file to an ASP 2.0 web service through HTTP 1.1 POST from a client-side application. If my web service function is declared as
<WebMethod()>
Public Function UploadFile(ByVal file as Byte(), ByVal fileName as String) as String
...
The test form says the request should take this form:
POST address_of_service HTTP/1.1
Host: <host>
Content-Type: application/x-www-form-urlencoded
Content-Length: length
file=string&file=string&fileName=string
How do I get my binary file data into that form? I've tried just converting the file data to a string and putting it in the body (file=<string_data_here>) but I get HTTP 500 errors back, complaining about not being able to convert it to System.Byte. I've got HTTP POST working fine elsewhere in my application with plain string parameters. Also, out of curiosity, why is it showing the file parameter twice?
Is it possible to get information about post field order in ASP.NET? I need to know whether some field was the last one or not.
I know I can do it through Request.InputStream, but I'm looking for a more high level solution without manually stream parsing.
Generally I'm doing testing of http post sent by my application and there is no practical usage for this in ASP.NET.
