一直覺得 UW.Template 應該還有改善的空間，因為網站大量使用這個物件
只要有一些些效能調教，對於整體效能應該有很大的幫助

昨天發現切版的程式 UW.Template => GetTemplateFromString
在使用 IndexOf 去尋找 <!--Key S--> 及 <!--Key E--> 時，
<!--Key E--> 可能有一些問題，因為他是從第0個位置開始找
而實際上他應該是從 <!--Key S--> 後面開始找比較對
所以後者的 IndexOf 要加個 StartIndex 參數值比較對

    StartP = StartP + StartKey.Length

    Dim EndP As String = Source.IndexOf(EndKey, StringComparison.OrdinalIgnoreCase)

    ' 應該修改為以下寫法 =>

    StartP = StartP + StartKey.Length

    Dim EndP As String = Source.IndexOf(EndKey, StartP, StringComparison.OrdinalIgnoreCase)    

另外 我也針對 StringComparison 做一些測試 
然後以一個 20KB 的 html 去抓出 <!--Content E--> 的位置
測試結果如下 (StartP 是 <!--Content S--> 後的起始位置)

0.0005085 No StartP

0.0002082 with StartP

0.0000157 StringComparison.Ordinal with StartP

0.0002768 StringComparison.OrdinalIgnoreCase, No StartP

0.0001105 StringComparison.OrdinalIgnoreCase with StartP

0.0002116 StringComparison.CurrentCulture with StartP

0.0002085 StringComparison.CurrentCultureIgnoreCase with StartP

結論: 
1. IndexOf 預設是以 StringComparison.CurrentCulture 方式尋找字串
2. 對於大塊字串，請盡量用 StartP 去找結束標籤位置，這樣速度會快很多，因為少爬了一段文字，此範例是差了2.5倍
3. 對於大塊字串，除非大小寫都要找，不然盡量用 StringComparison.Ordinal 來尋找字串，速度差了7~8倍

調整後:

<script type="text/javascript">

     CKEDITOR.replace('Content, { toolbar: 'basic', height: 360, allowedContent: {

               img: {

Windows 2008 的 SMTP 寄信時若遇到 "Helo command rejected: need fully-qualified hostname" ，可做以下的修改。

The fix is easy:

1. Open IIS
2. View the properties of you Default SMTP Virtual Server
3. Go to the “Delivery” tab
4. Click the “Advanced” button (in the bottom right corner)
5. Under “Fully-qualified domain name” enter a domain name that points to the server
6. Click Ok until you’re back to IIS

查了監控 snmp 的套件，還是 mrtg 最簡單，做個紀錄一下

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
先安裝 windows server snmp 服務，啟動​並進行設定

可參考：http://blog.faq-book.com/?p=1799
設定 public 的地方需輸入，會與 mrtg 的設定有關

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
安裝 ActivePerl，並下載解壓 mrtg 到任意目錄
官網：http://mrtg.cs.pu.edu.tw/download.en.html

這裏以 c:\mrtg 為例

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
設定 c:\mrtg\bin\127.0.0.1.cfg, 並執行 c:\mrtg\bin\perl mrtg 127.0.0.1.cfg 可跑一次
會產生 html&圖 到 WorkDir: 下，再設成 iis web 即可

c:\mrtg\bin\127.0.0.1.cfg 範例

建立 bat 排程每五分跑一次即可

mrtg.bat

perl mrtg 192.168.0.10.cfg

perl mrtg 192.168.0.20.cfg



rem 幫你建立 index.html

perl indexmaker --output c:\inetpub\wwwroot\mrtg\index.html 192.168.0.10.cfg 192.168.0.20.cfg

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
較麻煩的是 Target 的設定，為 snmp 的節點值，跟效能監視器裏的項目有點像

查到的較有用的
CPU Loading
Target[127.0.0.1-cpu]: .1.3.6.1.2.1.25.3.3.1.2.1&.1.3.6.1.2.1.25.3.3.1.2.2:public@127.0.0.1
其中 .1.3.6.1.2.1.25.3.3.1.2 固定，.1 .2 隨不同機器的 cpu 數 .3 .4 都有可能

Current Connections
Target[192.168.0.10-webusers]: .1.3.6.1.4.1.311.1.7.3.1.13.0&.1.3.6.1.4.1.311.1.7.3.1.14.0:public@127.0.0.1

Network Usage
Target[192.168.0.10-network]: \Realtek\ PCIe\ GBE\ Family\ Controller:public@127.0.0.1
這裏都會跟網卡名綁，通常用執行
perl cfgmaker --global "WorkDir: c:\inetpub\wwwroot\mrtg" --ifref=descr --ifdesc=descr public@127.0.0.1 --output network.cfg
它會幫你跑一遍路的節點，再挑出來用即可

Cpu 溫度找不到內建通用的，要安裝第三方套件，開其它篇寫

從 http://blog.ie-soft.de/post/2007/12/globalasax-events.aspx  抄來的. 留作參考

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

解壓縮至 c:\squid

指令
\sbin\squid.exe
squid -?
squid -z d:\squid\var\cache 暫存目錄設定
squid -i 加入服務

將某一檔案更新做法
C:\squid\bin>squidclient -h localhost -p 80 -m PURGE http://bserver.img.photosharp.com.tw/Image/Advert/360x120_v1_260x87s120.jpg

若不行需設定 squid.conf
參考 http://help.getbusi.com/kb/getbusi-alert-advance/removing-individual-objects-from-squid-cache
acl manager proto cache_object 後加入一行 acl Purge method PURGE
http_access allow manager localhost 後加入一行 http_access allow localhost Purge
http_access deny manager 後加入一行 http_access deny Purge

Web & Squid 共存(不同 IP 共用80Port)

如 192.168.0.203(Web), 192.168.0.201(Squid)
IIS 的網站需指定(192.168.0.203)

squid.conf 設定檔需修改 IP 位置
http_port 192.168.0.201:80 transparent

改變 IIS 監聽 IP 的範圍
=-=-=-= Windows Server 2003 =-=-=-=
Windows Server 2003 CD\Support\Tools\Support.msi 安裝後
C:\Program Files\Support Tools 下有程式 httpcfg
httpcfg delete iplisten -i 0.0.0.0
httpcfg set iplisten -i 192.168.0.203
=-=-=-= Windows Server 2008 =-=-=-=
netsh 進入指令模式
netsh>http
netsh http>add iplisten ipaddress=192.168.0.203:80 (會取代 0.0.0.0)

重啟指令
net stop http /y
net start w3svc查看指令

netstat -an
tcp 0.0.0.0:80 需沒有
tcp 192.168.0.203:80 需有

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HTTP\Parameters\ListenOnlyList
會列出開機時會載入的 httpcfg set iplisten，若 ip 有設錯 iis 可能會出現 "指定的網路名稱格式不正確"
