The file.zip is fixed in code behind.
I have a website that has anonymous authentication enabled. Now for a particular folder I want the users to be logged in with a userid and password. The user id and password is going to be same for everyone.
Eg user id is TEST and Password is answer. How can I do that?
I went in to that folder ->properties->directory security->edit-> And I disabled the anonymous access
But where should I add the User Id and Password? Under which option.
I'm running IIS 6 with ASP.NET 2.0.I enabled windows authentication for a folder in a website and gave permissions to a user. When I navigate to the page, the passowrd prompt pops up as expected and when entered correctly, the page loads. The page contains a file upload control. When I try to upload a file, the password prompt keeps popping up. ultimately it ends up as a 401 error. The user account does have write permissions to the floder, so I'm not understanding why I can get to the page with the credentials, but can't upload anything to that folder.

I'd like my application to query a csv file from a secure website. Currently I have the user login to the site, manually query the csv, and have my application load the file locally. I'd like to automate this by having the user enter his login information, authenticating him on the website, and querying the data. The application is written in C# .NET. The url of the site is: https://www2.emidas.com/default.asp.
I've tested the following code already and am able to access the file once the user has already authenticated himself and created a manual query.
System.Net.WebClient Client = new WebClient();
Stream strm = Client.OpenRead("https://www3.emidas.com/users/<username>/file.csv");
Here is the request sent to the site for authentication. I've angle bracketed the real userid and password.

I would like to connect to a password protected shared location that has an access database using an ASP page. I have the user name and password needed to connect to the shared location but I am not sure how to set up the connection string in order to get this done.

When a user that has their IE set to save passwords hits my "Reset Password" form, the first text box set with TextMode set to "Password" is populated with the users saved password. Understandable, this is not the affect I would like as this is their "old" password. I cannot set the text of a text box with mode set to "Password" (naturally). Does someone know how to suppress or clear this value when IE is saving passwords?
