Code Example Files The example consists of the following files: Web.config Global.asax Default.aspx ExceptionUtility (to be put in the App_Code folder) GenericErrorPage.aspx HttpErrorPage.aspx Http404ErrorPage.aspx DefaultRedirectErrorPage.aspx Web.config The following example shows the Web.config file. The customErrors section specifies how to handle errors that occur with file types that are mapped to ASP.NET, such as .aspx, .asmx, and .ashx files. (In IIS 6.0 and in IIS 7.0 in classic mode, static content files such as .html and .jpg files are not mapped to ASP.NET.) The settings in the example customErrors section cause any unhandled HTTP 404 (file not found) errors to be directed to the Http404ErrorPage.aspx file. These HTTP 404 errors would occur if a request were made for an .aspx file, .asmx file, and so on an
R. SpinellaMay 31, 20110 0 0 0 I am sure alot of us when sending mail from a web application, we sometimes run https://blogs.msdn.microsoft.com/jrspinella/2011/05/31/handling-exceptions-when-sending-mail-via-system-net-mail/ intosome unforeseen error becuase the mail being sentthrew an exception. How do we solve this?Do we just throw the exceptionand that's it. No, If we look into this problem a little closer, the majority of mail server interruptions are very temporary, only lasting a few seconds. Instead of throwing the exception right away, why not asp.net error trysending the mail again? If there is a problem of any kind at the SMTP server level, the server reports an exception, you willprobally useSmtpException to handle this. While using the SmtpException works well, its functionality is limited in determining exactly how the send failed. Why do we care? Well, sometimes our mail server is experiencing asp.net error handling a serious issue, and most likely, there’s nothing you can do about it. But, when a SMTP server reports an error, the actual problem is not with the server itself but with an individual mailbox. The most common cause of mailbox issues are as follows: The destination mailbox is currently in use. If this occurs, only lasts a short amount of time. The mailbox is unavailable. This may mean that there is actually no such address on the server, but it may also mean that the search for the mailbox simply timed out. The transaction with the mailbox failed. The reasons for this can be somewhat mysterious; but like a stubborn web page, sometimes a second nudge is all it takes to do the trick. What does this tell us? With a little more coding, we could gracefully recover from the majority of email send failures by detecting these particular conditions and attempting the send a second time. Remember, if a second mail send happen
