use session

if (myAccountInfo != null) {
HttpContext.Current.Session[ACCOUNT_KEY] = myAccountInfo;

// Determine where to redirect the user back too
// If they came in from the home page, take them to a similar page
if (FormsAuthentication.GetRedirectUrl(userId, false).EndsWith(URL_DEFAULT)) {

FormsAuthentication.SetAuthCookie(userId, false);
HttpContext.Current.Response.Redirect(URL_ACCOUNTSIGNIN, true);

}else{
// Take the customer back to where the came from
FormsAuthentication.SetAuthCookie(userId, false);

HttpContext.Current.Response.Redirect(FormsAuthentication.GetRedirectUrl(userId, false), true);
}

return true;

}else {
// Login has failed so return false
return false;
}
}

public bool CreateAccount(AccountInfo newAccountInfo){

try {
// Creata a new business logic tier
Account account = new Account();

// Call the insert method
account.Insert(newAccountInfo);

// Store the data in session state and store the authenticated cookie
HttpContext.Current.Session[ACCOUNT_KEY] = newAccountInfo;
FormsAuthentication.SetAuthCookie(newAccountInfo.UserId, false);

//Finally forward to the welcome page
HttpContext.Current.Response.Redirect(URL_ACCOUNTCREATE, true);


}catch {
return false;
}

return true;
}

/// <summary>
/// A method to process an updated account
/// </summary>
/// <param name="updatedAccountInfo">Updated account information</param>
public void UpdateAccount(AccountInfo updatedAccountInfo){

// Create the business logic tier
Account account = new Account();

// Call the udpate method
account.Update(updatedAccountInfo);

//Store the update info back in session state
HttpContext.Current.Session[ACCOUNT_KEY] = updatedAccountInfo;

//Redirect the user to the my account page
HttpContext.Current.Response.Redirect(URL_ACCOUNTUPDATE, true);

}

/// <summary>
/// Retrieves the account information for a customer who has already logged in
/// The method assume the account information is in session state
/// If it can't find it the function will direct the user to login
/// </summary>
/// <returns>The account info for the currently logged in user</returns>
public AccountInfo GetAccountInfo(bool required){
AccountInfo myAccount = (AccountInfo)HttpContext.Current.Session[ACCOUNT_KEY];

if (myAccount == null){
if(required){
HttpContext.Current.Response.Redirect(URL_SIGNIN, true);

}
return null;
}else{
return myAccount;
}
}

/// <summary>
/// Retrieves favourtie category of a customer if we know who they are
/// The method assume the account information is in session state
/// </summary>
/// <returns>The customers favourite category</returns>
public string GetFavouriteCategory(){

AccountInfo myAccount = (AccountInfo)HttpContext.Current.Session[ACCOUNT_KEY];

if (myAccount != null && myAccount.IsShowFavorites) {
return myAccount.Category;
}else{
return null;
}
}

能讲讲原理吗

[bullion]

大家给点例子吧!

[bruce007]

redbb(. Dotneter .) 的思路是首先把用户的登陆信息都保存到session中。 当然登陆时他把用户的相关信息都取到了那个 AccountInfo 中， 包括那个什么FavouriteCategory 都取道了AccountInfo中， 保存到session中去了， 当有需要用户的信息时， 就到session中去读：
AccountInfo myAccount = (AccountInfo)HttpContext.Current.Session[ACCOUNT_KEY]; 当然在读session, cache这类东西时都要判断读出的冬冬是不是为空， 是空的话，就说明用户的信息在session中没有了， 需要他重新登陆

购物栏用session做，quickstart里有一个例子，很好，又简单，但说明的问题很详细
