在没有 web 页面的情况下，如何使用 ASP.NET 检查 cookies 是否已启用？

Question

I am working on a desktop application that automates numerous websites and processes the returned data. This application will be run on a server and the user will connect with remote desktop. The automation breaks when the server doesn't have cookies enabled, and instead of having the application stop working, I would like to check the server settings and tell the user why it isn't working.

To do this, I decided to create an ASP.NET Web Service. I figured that the web service could store the cookie and then try to access the data. If the data is found, cookies are enabled and everything is good to go.

I have read numerous tutorials like: http://www.csharphelp.com/2006/05/c-and-cookies/ that explain how to store and access cookies through ASP.NET. All of these however use a website. The user clicks a button to generate a request and the web service can then send a response. I do not know how to make the process work without having a website, and I do not wish to automate a site of my own hosting as well. I feel like I should be able to run a method on my webservice and it should work.

Does anyone know how this would be done? I'd like a webservice that can handle request and response so I can create, store, and access cookies. I thank you for any help that you may offer.

EDIT:

I am working on an database driven application. Some of the pieces are automated web sites, where the user puts in some data and then the program opens up a webBrowser control, fills in the forms, and then formats the resulting data. I would like to test if cookies are enabled based on the users security privileges so that I can disable automation and allow the user to fill in the data on their own if required. Most of the websites require cookies to log in.

This will be running on various versions of Windows Server. By default I think the webBrowser control has the same security settings as Internet Explorer.

Answer 1

var request = (HttpWebRequest)WebRequest.Create("http://stackoverflow.com/");
request.Method =  "Head";
var response = (HttpWebResponse)request.GetResponse();
var usesCookies = !String.IsNullOrEmpty(response.Headers["Set-Cookie"]);

Answer 2

You can verify those keys on registry:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\Zones
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\Zones

Under those keys, you may see some keys like 0, 1, 2, 3... Each one is a Zone configuration.

Search for those entries in each Zone:

1A02
1A03
1A05
1A06

So you have to verify if those entries values are equals to 0.
