當使用 WebRequest 來 Get 網址時，出現"已經嘗試太多次自動重新導向"。
通常為對方網站有進行某種判斷。以下為試過的項目。
上次是將 CookieContainer 設定一個 New Net.CookieContainer 即可。
Dim http As Net.HttpWebRequest = Net.WebRequest.Create(Url)
http.Method = "GET"
http.ContentType = "application/x-www-form-urlencoded;"
http.UserAgent = "Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.0; Win64; x64; Trident/5.0)"
http.CookieContainer = New Net.CookieContainer
http.Referer = Url
void Application_BeginRequest(object sender, EventArgs e)
{
UW.WU.BlockHacker();
}
可以做一些基本的防駭.
在 Sys_Coonfig 中有兩個參數要設定: WEB_ERROR_ExceptionCountBeforeBlock, WEB_ERROR_ExceptionCountingIntervalInMinutes
另外還有一個參數: WEB_ERROR_DangerousKeywords, 內容請用逗號分隔, 若是發生 Exception 時, Form 或 QueryString 中含有指定的文字, 收到的警告信會標示為高重要性.
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
無法載入檔案或組件 'FredCK.FCKeditorV2' 或其相依性的其中之一。 存在某個不正常的 API 呼叫。 (發生例外狀況於 HRESULT: 0x800300FA (STG_E_ABNORMALAPIEXIT))

建議co個用過的來抄

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
設定檔重置

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"
