If the background webpage cannot be opened, is there something wrong with the code? _html/css_WEB-ITnose

I would like to ask if there is an error in the following code, causing the web page to display an error? ? I use the asp debugging tool locally but I can log in to the background normally
if session("MM_Logoutnow") = "" then
response.Redirect "sysdlck.asp"
end if
%>

There is nothing in the error message. Modify the display friendly http error message in the advanced tab in the IE browser properties and change Remove the hook in front of this item and look at the detailed errors.

Are you sure your URL is correct?

Are you sure your URL is correct? Could you please tell me clearly what URL it is? I can open it normally using the asp debugging tool locally.

Are you sure your URL is correct? Hello, could you please help me answer this question.

I’m so confused. There is only one url in your code, and you are asking about that url. Do you not know what a url is?
