Communication Between Client And Server Is HTTPS?
Nov 24, 2010
I have a web service with several web methods, each web method requires client machine to send their MAC Address and the server will validate this client base on this information (if not valid then return error) before proceeding to further operations. The communication between client and server is HTTPS. I only have about 20 clients or so. The question is is my way of doing this right/secure or not? If not then is there any simple way to do this?

I'm new to cryptography and I'm a bit stuck:
I'm trying to connect (from my development environment) to a web service using HTTPS. The web service requires a client certificate - which I think I've installed correctly.
They have supplied me with a .PFX file. In Windows 7, I double clicked the file to install it into my Current User - Personal certificate store.
I then exported a X509 Base-64 encoded .cer file from the certificate entry in the store. It didn't have a private key associate with it.
Then, in my app, I'm attempting to connect to the service like this:
var certificate = X509Certificate.CreateFromCertFile("xyz.cer"));
var serviceUrl = "https://xyz";
var request = (HttpWebRequest) WebRequest.Create(serviceUrl);
request.ClientCertificates.Add(certificate);
request.Method = WebRequestMethods.Http.Post;
request.ContentType = "application/x-www-form-urlencoded";
I get a 502 Connection failed when I connect.
Is there anything you can see wrong with this method? Our production environment seems to work with a similar configuration, but it's running Windows Server 2003.

I am planning a SaaS system, to be written in C#, ASP.NET using WCF that has two separate components:
On a static IP web server in the cloud will be a web app, common to all clients. Inside each client's office will be another app, installed on a server with IIS.
The site app will obviously be able to connect to the web services published on the web site. But here's the rub - I also want the web app to be able to initiate a connection to the site app... and the on-site server may not necessarily have a static IP. I can't control this, because we may have hundreds of clients at some point in the future, and we cannot limit our saleability by insisting that the customer has a server with fixed IP.
So, how to do this?
I could have the site apps "checking in" with the web every minute or so, to give the web app the possibility of responding with a "while you're here, do x,y,z..." but that seems very inelegant. Also, if we're talking about hundreds of clients, I don't want to be bombarding my web server with all these "hi there!" messages if they're not actually required.

There are 2 web-servers involved:
Webserver1 has been in the organization a few years and is hosting/running multiple websites with https encryption (app1.ourcompany.com, app2.ourcompany.com, etc). It has a valid, signed certificate.
Webserver2 is a new server, for which I am responsible. I am tasked with setting up https and getting the certificate, etc. It has a web app running on it, but it does not have a domain name (only has an IP address)...which as I recently learned, is a requirement for a signed certificate.
What I'd like to know is this -- is it possible to set up a site on Webserver1 that points to the site I'm hosting on Webserver2 (ie SiteOnWebserver2.ourcompany.com) which also utilizes the Webserver1's signed/verified certificate?

I previously asked on StackOverflow how to parse XML downloaded programmatically by my ASP.net application. By this, I mean that the user visits https://www.example.com/page1.aspx. The code-behind for page1.aspx is supposed to somehow download and parse an xml file located at https://www.example.com/foo.xml.
I received good answers about how to parse the XML. However, I've been out of luck with being able to retrieve XML from my secure HTTPS server.
I am looking at a situation where https://www.example.com/foo.xml authenticates requests with a cookie. (third party system, not Forms Authentication). The answer I received to my question about how to download and parse XML suggested that I use the System.Net.WebClient class. I read that the WebClient class must be customized to work with cookies. Therefore, I wrote the following code:
public class WebClientWithCookies : WebClient
{
private CookieContainer m_container = new CookieContainer();
public CookieContainer CookieContainer
[Code]....
However, when the request is received at https://www.example.com/foo.xml, there are no cookies in the request, and so it doesn't work.

If I have something like the following:
<asp:TextBox id="test" runat="sever"></asp:TextBox>
<asp:RequiredFieldValidator runat="server" ControlToValidate="test"
ErrorMessage="Required"></asp:RequiredFieldValidator>
<asp:Label runat="server" id="lblStatus"></asp:Label>
if in the code behind, I set the label to "You must enter a value if the textbox is empty" to validate it on the server side and this is fine, but if javascript is enabled, I don't want to show the client side validation and the server side label together. Is this something where I would just have to disable the client-side validators if javascript was enabled?

We've got a client app which connects using TCP to a server. Additionally, the client app makes use of .NET remoting to talk to another piece of locally running code.
I'm tasked with creating a "Client Simulator" to do some testing, where we'd need to have 100's of clients connected simultaneously to the server. Ideally, this would work out great if I were to run each client in it's own space, such as a VM, but this is not logistically feasible.
how to handle this? Is there a tool that could do something like this? Or some sort-of .NET concept I could use?

I have a user control which contains a CustomValidator which is used according to whether a RadioButton is checked or not (there are several RadioButtons, I'm only showing the relevant one)
<asp:RadioButton runat="Server" ID="RadioBetween" GroupName="DateGroup" CssClass="date_group_options_control_radio" />
[code]...
There is some client + server side validation code (the server side code does exactly the same thing and is skipped for brevity)
<script type="text/javascript">
function ValidateDateFields_Client(source, args) [code]...
There are two instances of this control in the page. When running the client side version it hits the wrong one (the version of the control which is disabled). You can see from the generated HTML both are correctly specified. I'm not sure how .NET works out which clientside function to call given they both have the same name.
<script type="text/javascript">
//<![CDATA[
var ctl00_MCPH1_QueryTextValidator = document.all ? document.all["ctl00_MCPH1_QueryTextValidator"] : document.getElementById("ctl00_MCPH1_QueryTextValidator");
[code]...
Do i need to add something in to scope it? What's the best way to achieve this? If I disable the loading of the second control everything works fine.

I'm going to create my own project, and i have some difficulties with technology selection. I will have client application(windows forms) and web service. Data exchange between clients will be only by using this web service. Data will be like image stream,so I don't know which technology to use. I started to look at WCF, but i don't know a lot about it.

ASP.NET 2.0 and COM Port Communication
I have a managed DLL which communicates with the devices attached on COM/Serial ports. The desktop Winforms application sends requests on ports and receives/stores data in memory. In Winforms app I have added a reference to DLL and I am using the methods. This works well. Now, there is a situation where I need to show this data from serial/com port on a web-page. And also users should be able to send requests to the ports using this DLL. I have made a web app in ASP.NET (2.0). Added a reference to the DLL. I am able to use this DLL, the DLL communicates on the COM upon button click on web-page and also the response is shown on web page. However I am not happy with the approach and strongly feel that this is a bad approach. Also the development server crashes after 3 -4 requests. What is the best approach in this scenario. If I use a windows service then how would my ASP.net app will communicate with the Weindows service.Or can this be easily done using WCF. I have not used WCF any time nor any of .net remoting technique.

So I am working on a project in ASP.NET MVC 2 with C#.I have a View with a file upload but this is a flash component (.swf).The result of the file upload (the storing of the file and processing of data in the database) is done in a HTTPHandler.I would like the HTTPHandler to send information to my active controller.
Is there a way to get the controller that was used to load the view? I'm having problems finding information about it online.

I'm running an ASP.NET WebService on IIS 6.0 that shows a lot of HTTP 500 (probably just exceptions from the WebService) inside the log at %systemroot%System32LogFilesW3SVC1 on a customers site.
Is it possible to log the content of those HTTP responses and there requests without modifying the WebService using IIS or a plug-in for IIS?
I thought of using Wireshark or Fiddler to sniff on the HTTP traffic but I would prefer to just turn on an option inside IIS to make him log the communication (this should not be to hard since it is logging the requested URLs anyway)

I have an ASP.NET app running on a webserver. A third party is created another app in PHP which needs to send data to my app for processing. Initially it was assumed that the PHP app would be deployed elsewhere so we agreed that the communication would occur over the internet via HTTP (over SSL). My app would simply use a generic handler (ashx) file to recieve the data and send confirmation back.
Now it seems that the PHP app might be deployed on the same machine as my app. I like the fact that using HTTP (as opposed to say direct database access), the PHP app needs to know nothing at all about how my app works. But using the public internet seems silly for communication between two apps on the same machine. If the PHP app simply used a localhost address, would this ensure that all the data stays within the machine? Is there a better way to do this?

I am create an iPhone app that needs to talk to a Windows C# app. The app will run as either a Service or Form Application.
What would be the best way to accomplish this? Ideally exposing a service-type architecture would be best as I don't need a stateful connection (stateless is fine in this case).
Can a WCF service hosted by my app using a form of TCP binding be consumed by my iPhone? Or can an app host using httpBinding without the aid of IIS or some other web server?
