If you want to disable the content after response. sendredirect (URL);, add
Return; statement, but directly add return; sometimes an error is reported. How can this problem be solved?
You can change the Syntax:
If (1 = 1 ){
Return;
}
OK. The problem is solved !! [Understanding: directly using the content after the return statement to report an error because it is impossible to execute the statement. The addition of a permanent condition seems to have eased the conflict, and the result is almost passed]
