原來的做法，在 window.load 時就執行一段 longcode，window.load 的時間約在 736 ms:
$(window).load(function () {
UpdateQty();
});
用 setTimeout 去呼叫 UpdateQty 大概可以省下 200 ms，只要 507 ms 就可以完成 window.load，如下圖。
$(window).load(function () {
window.setTimeout("UpdateQty();", 100);
});

之中 Methods 的章節，要注意的是 minlength, maxlength, rangelength 三個參數的 length 是小寫，有一些 Blog 會把 L 寫成大寫，然後試半天都試不出來 :P
限定 5 ~ 20 個英文字元或數字的寫法:
passwordformat: true
由於網站的user來自全世界各地，而我們網站產生的時間卻是Server的時間
因此需要使用javascript來做一些轉換，讓user看到是他當地的時間
1. Server端產生具有時區的時間字串，用特定的span + class把它包起來, 時間格式 DateTime.ToUniversalTime().ToString("r")
<span class="timeString">Fri, 31 Aug 2012 10:57:04 GMT</span>
2. Client端利用jQuery於網頁load的時候將所有時間轉換成當地時間
這個地方我用了 date.format.js 來轉換成當地時間 (參考 http://blog.stevenlevithan.com/archives/date-time-format )
$(".timeString").each(function () {var content = $(this).text();var d = new Date(content);if (!isNaN(d)) $(this).text(d.format("yyyy-mm-dd hh:MM tt"));});
這樣user看到的時間就不會錯了
HttpApplication Events:
Application_AcquireRequestState
Occurs when ASP.NET acquires the current state (for example, session state) that is associated with the current request.
Application_AuthenticateRequest
Occurs when a security module has established the identity of the user.
Application_AuthorizeRequest
Occurs when a security module has verified user authorization.
Application_BeginRequest
Occurs as the first event in the HTTP pipeline chain of execution when ASP.NET responds to a request.
Application_Disposed
Adds an event handler to listen to the Disposed event on the application.
Application_EndRequest
Occurs as the last event in the HTTP pipeline chain of execution when ASP.NET responds to a request.
Application_Error
Occurs when an unhandled exception is thrown.
Application_PostAcquireRequestState
Occurs when the request state (for example, session state) that is associated with the current request has been obtained.
Application_PostAuthenticateRequest
Occurs when a security module has established the identity of the user.
Application_PostAuthorizeRequest
Occurs when the user for the current request has been authorized.
Application_PostMapRequestHandler
Occurs when ASP.NET has mapped the current request to the appropriate event handler.
Application_PostReleaseRequestState
Occurs when ASP.NET has completed executing all request event handlers and the request state data has been stored.
Application_PostRequestHandlerExecute
Occurs when the ASP.NET event handler (for example, a page or an XML Web service) finishes execution.
Application_PostResolveRequestCache
Occurs when ASP.NET bypasses execution of the current event handler and allows a caching module to serve a request from the cache.
Application_PostUpdateRequestCache
Occurs when ASP.NET completes updating caching modules and storing responses that are used to serve subsequent requests from the cache.
Application_PreRequestHandlerExecute
Occurs just before ASP.NET begins executing an event handler (for example, a page or an XML Web service).
Application_PreSendRequestContent
Occurs just before ASP.NET sends content to the client.
Application_PreSendRequestHeaders
Occurs just before ASP.NET sends HTTP headers to the client.
Application_ReleaseRequestState
Occurs after ASP.NET finishes executing all request event handlers. This event causes state modules to save the current state data.
Application_ResolveRequestCache
Occurs when ASP.NET completes an authorization event to let the caching modules serve requests from the cache, bypassing execution of the event handler (for example, a page or an XML Web service).
Application_UpdateRequestCache
Occurs when ASP.NET finishes executing an event handler in order to let caching modules store responses that will be used to serve subsequent requests from the cache.
Application_Init
This method occurs after _start and is used for initializing code.
Application_Start
As with traditional ASP, used to set up an application environment and only called when the application first starts.
Application_End
Again, like classic ASP, used to clean up variables and memory when an application ends.
Session Events:
Session_Start
As with classic ASP, this event is triggered when any new user accesses the web site.
Session_End
As with classic ASP, this event is triggered when a user's session times out or ends. Note this can be 20 mins (the default session timeout value) after the user actually leaves the site.
Profile Events:
Profile_MigrateAnonymous
Occurs when the anonymous user for a profile logs in.
Passport Events:
PassportAuthentication_OnAuthenticate
Raised during authentication. This is a Global.asax event that must be named PassportAuthentication_OnAuthenticate.
Possibly more events defined in other HttpModules like:
System.Web.Caching.OutputCacheModule
System.Web.SessionState.SessionStateModule
System.Web.Security.WindowsAuthentication
System.Web.Security.FormsAuthenticationModule
System.Web.Security.PassportAuthenticationModule
System.Web.Security.UrlAuthorizationModule
System.Web.Security.FileAuthorizationModule
System.Web.Profile.ProfileModule
Ex:
Dim Conn As SqlConnection = UW.SQL.GetOpenedConnection
Dim Tran As SqlTransaction = Conn.BeginTransactionTry
Dim C As Int32 = UW.SQL.GetSingleValue("Select Counter From TableA Where Id = 1", Tran)
C = C + 1
UW.SQL.executeSQL("Update TableA Set Counter = " & C & " Where Id = 1", Tran)
Tran.Commit()
Catch ex As Exception
Tran.Rollback()
UW.WU.DebugWriteLine(ex.ToString, True, True)Finally
If Conn.State <> ConnectionState.Closed Then
Conn.Close()
End IfEnd Try
以上的程式由兩個 Session 同時執行時, 並不能保証 Counter 會被加 2
若是要保証兩個 Session 都會把 Counter 加一(總共加 2), 要把以下這一行
Dim C As Int32 = UW.SQL.GetSingleValue("Select Counter From TableA Where Id = 1", Tran)
改為
Dim C As Int32 = UW.SQL.GetSingleValue("Select Counter From TableA With(XLock) Where Id = 1", Tran)
A potentially dangerous Request.Form value was detected from the client (ContentBody_txtContent="<style type="text/cs...").
.aspx新增了<%@ Page validateRequest="false"%>
最後找到還需要在web.config裡面新增<httpRuntime requestValidationMode="2.0" />

安裝 GeoIP:
安裝 Perl 模組
在 cmd 下, 輸入 "ppm install Geo-IP-PurePerl"
下載 Data:
1. Install Perl module. Open your Perl Package Manager which is stand for ppm.bat in bin folder.
2. Install Geo-IP-PurePerl and Geo-IPfree module.
3. Download the GeoIP data from, http://www.maxmind.com/download/geoip/database/. (要 dat 的格式, 不要 csv 的)
4. Extract the data and place it to C:\Perl\lib\Geo\IP folder.
5. Open the awstats.base.conf(C:\awstats\wwwroot\cgi-bin) and paste the following command.
LoadPlugin="geoip GEOIP_STANDARD C:\Perl\lib\Geo\IP\GeoIP.dat"
6. You have done and you will see the result in next update.
