your system. For example, if your application unsuccessfully tries to log in to a database, it should not display an error message that includes the user name it is using. There are a number of ways to control error messages, including the following: Configure the application not to show verbose error messages to remote users. (Remote users are those who request pages while not working on the Web server computer.) You can optionally redirect errors to an application page. Include error handling whenever practical and construct your own error messages. In your error handler, you can test to see whether the user is local and react accordingly. Create a global error handler at the page or application level that catches all unhandled exceptions and routes them to a generic error page. That way, even if you did not anticipate a problem, at least users will not see an exception page. To configure the application to turn off errors for remote users In the Web.config file for your application, make the following changes to the customErrors element: Set the mode attribute to RemoteOnly (case-sensitive). This configures the application to show detailed errors only to local users (tha

classic ASP scripts were sent to a Web browser, by default. Because these error messages might reveal sensitive information to malicious users, IIS 7 and above disables this feature by default. When your classic ASP scripts encounter https://msdn.microsoft.com/en-us/library/994a1482.aspx an error in IIS, you receive the following error message by default: An error occurred on the server when processing the URL. Please contact the system administrator. If you are the system administrator please click here to find out more about this error. You can customize the ASP script error message, and also determine whether to return the script errors to a Web browser. Note: As a best practice for security, you should https://www.iis.net/learn/application-frameworks/running-classic-asp-applications-on-iis-7-and-iis-8/classic-asp-script-error-messages-no-longer-shown-in-web-browser-by-default only enable sending ASP script error messages to a Web browser on a development or test computer; returning script error messages to a Web browser can unintentionally expose more information than you intended to show. Working with User Access Control You need to make sure that you follow the steps in this document by using an account that has full administrative permissions. This is best accomplished by using one of two methods: Log in to your computer by using the local administrator account. If you are logged in using an account with administrative permissions but that is not the local administrator account, open all applications and all command prompt sessions by using the "Run as Administrator" option. These above conditions are required because the User Account Control (UAC) security component in Windows Vista and Windows Server 2008 will prevent administrative access to the IIS configuration settings. For more information about UAC, see the following documentation: User Account Control Customizing Classic ASP Error Messages The configuration settings that you use to customize these settings are in the following list: scriptErrorMessage This is an optional string attribute that specifies the error message that will be sent to the browser when specific debugging errors are not sent to the client. scriptErrorSentToBrowser This is an optional Boolean attribute that specifies whether the writing
are essential during the development and debugging stages. The error messages can http://www.chestysoft.com/asp-error-messages.asp be switched on through IIS properties but they require two adjustments. Part of the IIS property screen is shown below and the two sections that need changes are highlighted, ASP and Error Pages. First, double click the ASP icon to open the ASP page. Expand the Debugging Properties node and set Send Errors To error message Browser to True. This is not enough to get a detailed error message. At this stage it will only show the error defined by Script Error Message. Go back to the IIS properties as shown above and open the section for Error Pages. Select the link marked Edit Feature Settings from the list on the error message in right and this opens the following dialogue. If you are viewing the pages with the server's own browser, you can select the bottom radio button as shown. This is the recommended selection for a live website because it will send custom error pages to an end user. Customer error pages are configured at the previous screen. If you are developing on a different computer you must set the radio button to Detailed Errors. This will send the full error message with an error code and line number. This is not advisable for a live website and the radio button should be changed back when debugging is complete. Making errors display in Internet Explorer Internet Explorer does not show proper error messages by default. To switch them on, go into Internet Options and find the checkbox marked "Show friendly HTTP error messages" which is located under the Advanced tab and Browsing.
