The configuration 404 page in the configuration file is as follows:

The copy code is as follows:

When visiting the website, the error page can be displayed normally, but the HTTP status code is 302, which is very unfriendly to SEO. Follow these steps to modify the error page to return the correct SEO-friendly status code:

1. Add the code to 404.aspx:

Response.Status = "404 Moved Permanently"

/ / /

Private void FileNotFound_Error ()

{

HttpException erroy = Server.GetLastError () as HttpException

If (erroy! = null & & erroy.GetHttpCode ())

{

Server.ClearError ()

String path = "~ / 404.aspx"

Server.Transfer (path)

/ / Context.Handler = PageParser.GetCompiledPageInstance (path, Server.MapPath (path), Context)
