问题 Whats the best way to achieve the above? I do know that it can be achieved at HttpModule level. Is it possible just via web.config(easier and faster to code execute). 回答1: It's easy to do this with the URL rewrite module through the web.config : <rewrite> <rules> <clear /> <rule name="Redirect naked domains to www.domain.com" stopProcessing="true"> <match url="(.*)" /> <conditions logicalGrouping="MatchAll"> <add input="{HTTP_HOST}" negate="true" pattern="^www\." /> <add input="{REQUEST_URI}"

问题 In ASP.NET you can set the Response.StatusCode to for example 404. Should the status line / description always be set?

问题 We have been having a random issue with our live website. We're not sure what exactly is causing the issue. We tried clearing the temporary files but the issue happened again. We even killed the IIS app_pool so that it wouldn't be holding any of them in memory. As soon as we put the site back up we get this error again.
