How to prevent downloading when user's allocated size or period exceeds
It is handled using httphandler in ASP.NET. The handler code is bellow ..
public class DownloadHandler : IHttpHandler
{
public DownloadHandler()
{
//
// TODO: Add constructor logic here
//
}
public bool IsReusable
{
get { return true; }
}
/// <summary>
/// Enables processing of HTTP Web requests by a custom HttpHandler that implements the <see cref="T:System.Web.IHttpHandler"/> interface.
/// </summary>
/// <param name="context">An <see cref="T:System.Web.HttpContext"/> object that provides references to the intrinsic server objects (for example, Request, Response, Session, and Server) used to service HTTP requests.</param>
public void ProcessRequest(HttpContext context)
{
long currentDownloadedAmount = 0;
try
{
// File name
string fileName = context.Request.Url.Segments[context.Request.Url.Segments.Length - 1]; ;
fileName = context.Server.UrlDecode(fileName);
string filePath = @"d:\ATVMovies\" + fileName;
FileStream fileStream = new FileStream(filePath, FileMode.Open, FileAccess.Read);
// Total bytes to read
long dataToRead = fileStream.Length;
context.Server.ScriptTimeout = 600;
context.Response.Buffer = true;
context.Response.Clear();
context.Response.ContentType = "application/octet-stream";
context.Response.AddHeader("Content-Disposition",
"attachment; filename=\"" + filePath + "\";");
context.Response.AddHeader("Content-Length", dataToRead.ToString());
int ChunkSize = 1024; //256 MB =256*1024
// Buffer to read 10K bytes in chunk
byte[] buffer = new Byte[ChunkSize];
int offset = 0;
int length;
long UserRestAmount = MovieHelper.getMovieBalance((Guid)Membership.GetUser().ProviderUserKey);
// Read the bytes.
while (dataToRead > 0)
{
// Verify that the client is connected.
if (context.Response.IsClientConnected)
{
// UserRestAmount = MovieHelper.getMovieBalance((Guid)Membership.GetUser().ProviderUserKey);
if (UserRestAmount <= 0)
{
fileStream.Close();
dataToRead = -1; //disconnected
break;
}
// Read the data in buffer
length = fileStream.Read(buffer, offset, ChunkSize);
//offset += ChunkSize;
// Write the data to the current output stream.
context.Response.OutputStream.Write(buffer, 0, (int)length);
// Flush the data to the HTML output.
context.Response.Flush();
buffer = new Byte[ChunkSize];
dataToRead = dataToRead - length;
currentDownloadedAmount += length;
UserRestAmount -= length;
}
else
{
//prevent infinite loop if user disconnects
dataToRead = -1;
}
}
if (dataToRead == 0 || dataToRead == -1) // complete or disconnected
{
MovieHelper.UpdateDownloadSize((Guid)Membership.GetUser().ProviderUserKey, currentDownloadedAmount);
currentDownloadedAmount = 0;
}
fileStream.Close();
}
catch (Exception ex)
{
MovieHelper.UpdateDownloadSize((Guid)Membership.GetUser().ProviderUserKey, currentDownloadedAmount);

context.Response.Write(ex.Message);
}
}

Step by step of ASP.NET membership
Step by step of ASP.NET membership
1. Run aspnet_regsql.exe which located in C:\Windows\Microsoft.NET\Framework64\v4.0.30319. This wizard gets connection info and creates some database tables, views, SPs with prefix ‘aspnet_’.
2. Set in your web.config the following lines
<connectionStrings>
<add name="USRDBConnectionString" connectionString="Data Source=172.168.10.40;Initial Catalog=TvLibrary;User ID=sa;Password=sa1234;Max Pool Size=75;Min Pool Size=5;" providerName="System.Data.SqlClient"/>
</connectionStrings>
<membership>
<providers>
<clear/>
<add name="AspNetSqlMembershipProvider" type="System.Web.Security.SqlMembershipProvider" connectionStringName="USRDBConnectionString" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="false" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10" applicationName="/"/>
</providers>
</membership>
<profile>
<providers>
<clear/>
<add name="AspNetSqlProfileProvider" type="System.Web.Profile.SqlProfileProvider" connectionStringName="USRDBConnectionString" applicationName="/"/>
</providers>
</profile>
<roleManager>
<providers>
<clear />
<add connectionStringName="USRDBConnectionString" applicationName="/"
name="AspNetSqlRoleProvider" type="System.Web.Security.SqlRoleProvider" />
<add applicationName="/" name="AspNetWindowsTokenRoleProvider"
type="System.Web.Security.WindowsTokenRoleProvider" />
</providers>
</roleManager>
3. Then go menu Website->ASP.NET configuration
