Iis7.5-http Error 404.0-not found-0x80070002 error analysis and solution

When a customer migrates to IIS7.5, the site reports an HTTP error 404.0-not Found error. The process is as follows:

Customer Environment: Framework 2.0,iis7.5,web Site set, no source code, application Chime considered Classic mode.

The URL of the error page is as follows: Http://localhost/HL2008/UI/AutoMonitor/135?autorun=true

See this URL address, the first reaction is HttpModule was rewritten, through the. NET Reflector 7.0 anti-compilation HL2008.Web.Common.dll, found Urlrewriter class, Implements the System.Web.IHttpModule interface.

Continue tracking, the core code of this class is a jump operation.

void Context_beginrequest (object sender, EventArgs e) {//string path = string.            Format ("~/action/requesthandler.aspx?id={0}&{1}", "Yeyang", HTTPCONTEXT.CURRENT.REQUEST.RAWURL);            HttpContext.Current.RewritePath (Path,false); ILog log = log4net. Logmanager.getlogger (Methodbase.getcurrentmethod ().            DeclaringType); Log.            Info ("Demohttpmodule context_beginrequest is called"); String p = string.

  public static bool Isautomon (out string permissionid) {PermissionID = Getpermissionid (); Return!string.

Count > 0) {permissionid = mc[0]. groups["PermissionID"].            Value;        } return PermissionID; }

So the preliminary decision for HttpModule is not activated, through the web search, to find a similar post (http://q.cnblogs.com/q/38592/), which refers to IIS7.5 under the httpmodules use appears: 404 To resolve, you need to add the modules configuration to the <system.webServer> configuration section.

In the Web. config at this point, there are modules and handlers configurations under <system.web> under the httpmodules and httphandlers configurations,<system.webserver>.

The problem is still unresolved, the application is not activated by inserting the modules component of the Log4net log into the output log in the original application http://localhost/HL2008/UI/AutoMonitor/ 135?autorun=true the request had been terminated before. The log is as follows:

The problem is defined as themodules is called, but the request is not activated http://localhost/HL2008/UI/AutoMonitor/135?autorun=true.

To continue, set the application pool to Integrated mode, when IIS errors are as follows:

HTTP Error 500.22-internal Server error detected an ASP. NET setting that is not applicable in integrated managed pipeline mode. Module: Configurationvalidationmodule Notification: BeginRequest handler: Staticfile error code: 0x80070032

The key information is as follows:

Most likely cause: This application defines the configuration in the System.web/httpmodules section.

So the System.web/httpmodules configuration section was removed.

To initiate a request to continue HTTP error, the key information is as follows:

? This application defines the configuration in the System.web/httphandlers section.

Remove the System.web/httphandlers configuration section.

Initiate the request. The log contents are as follows:

2015-01-12 22:03:18,058 [6676] INFO  demo.demohttpmodule [(NULL)] < (NULL) >-demohttpmodule init called 2015-01-12 22:03:18,136 [6676] INFO  demo.demohttpmodule [(NULL)] < (NULL) >-Demohttpmodule context_beginrequest Called 2015-01-12 22:03:18,136 [6676] INFO  demo.demohttpmodule [(NULL)] < (NULL) >-Demohttpmodule Getpermissionid is called 2015-01-12 22:03:18,136 [6676] INFO  demo.demohttpmodule [(NULL)] < (NULL) >-the URL address is [/ Hl2008/ui/automonitor/135?autorun=true]2015-01-12 22:03:18,136 [6676] INFO  demo.demohttpmodule [(NULL)] < ( NULL) >-Demohttpmodule Context_beginrequest-globaldefine.isautomon = = True is called

The problem is finally solved.

Summarized as follows:

IIS7.5 404, the HttpModule in System.Web is registered to system.webserver modules, and if the application pool is in Classic mode, module is not activated correctly. An abnormal termination occurs.

The module can be activated correctly only if the application pool is switched to integrated mode and the System.Web httpmodules and httphandlers are completely removed.
