![]() ![]() Advanced Logging extension subscribes to GENERAL_REQUEST_START event in the pipeline. Logging two events instead of one is by-design for Advanced Logging extension. Multiple identical logs in Advanced Logging Make sure to change the file extension to aspx (For example: 404.aspx). ~/error/404.htm).Īs a generic solution, adding the line below into the custom error page should solve the issue. – IIS doesn’t handle application relative paths both for “Redirect” and “ExecuteURL” as handled by Asp.Net (e.g. If you set path to browsers do the right thing and send the new request to instead. If path is set to “/otherpath/otherpage.htm”, this will be used as the destination and most browsers send this request back to the same host. – Custom error module blindly uses the path as location header value and send a 302 response. – If path doesn’t start with “/” or “ server will produce 404 when trying to execute the URL. – When path starts with “/”, it is assumed as URL for the current site and do a child execute on that. ![]() – If path starts with “ exact URL specified by path is executed. When child execute produce some other error, that error code along with child execute response is returned. If this request is supposed to be executed by some other application pool, IIS core will generate 403.14. Child request will enter the pipeline in the same worker process. On successful child execute, client will see a 200 response. ![]() Response returned by executing the URL is returned to client as response. User’s browser makes another request to the given URL. However, responseMode="Redirect” send 302 response with the custom error page URL to the user. 17:33:25 ::1 GET /app1/oopp – 80 – ::1 Mozilla/5.0 (Windows NT 10.0 WOW64 Trident/7.0 Touch rv:11.0) like Gecko – 404 0 2 46 Incorrect (first line) and correct (second line) status codes BackgroundĪs mentioned in this blog post, responseMode=”ExecuteURL” executes the URL in the custom error configuration sends the response to the user Therefore, IIS logs 200 instead of 404 status code. IIS log that shows the correct status code (404) after the change: Once I changed ExecuteURL to Redirect in the responseMode attribute, IIS started logging 404 errors. I have the configuration below that redirects users to a custom page when there is a 404 error. The root cause -in my case- is the custom error configuration in the web.config file. What to do if you see 200 instead of 404 status code Looking for a way to determine user browsers from IIS logs? Check this post out. However, in some environments the file contains the phrase types="CgiModule" instead of modules="CgiModule".17:32:28 ::1 GET /app1/kkrr1 – 80 – ::1 Mozilla/5.0 (Windows NT 10.0 WOW64 Trident/7.0 Touch rv:11.0) like Gecko – 200 0 0 0 Add the text allowPathInfo="true" after the word “ unspecified”įor most servers, the above is enough to solve the problem.Launch NOTEPAD.EXE and edit the file ‘ web.config’:.Using Windows Explorer, open the cgi-bin folder (TIP: By default, for Controller 10 on 32-bit Windows this is: C:\Program Files\ibm\cognos\c10\cgi-bin).=> Therefore (see Technote 1390241) on Windows 2008 you must also perform the following: NOTE: By default handlers defined in IIS 7.0 for either CGI or ISAPI modules do not process the full path information in a URI. Enter the values exactly as appear below (*.cgi, CgiModule, cgi-bin):.Locate and select/highlight the cgi-bin virtual directory.In the tree control in the left pane expand (machine name) > Web Sites > Default Web Site. ![]()
