hello..
In my site.. I want 404 error OR it should redirect to home page
when clicked on some folder or files (only some files)

how to do this.. I guess it done my changing file permissions..
currently these files are 777
I changed it in to different ways.. then my site is notworking
actually they are template files..

or may be this modification done through .htaccess
just tell me what to enter in .htaccess to make some files redirect to home page.. Ill enter the path of files

thanks

Are you using a cms? usually you can specify a 404 page from within your cms, also your hosting control panel should offer this too.

In my site.. I want 404 error

Just delete the files and you will get a 404 response.

Nope!

Well if your running on a window's sever (hosting package) or if you have a window's OS than you dont have to..because with windows you cant/dont have to set chmd777 permission..so just leave that part alone...now a 404 literally can mean a wide variety of issues..so be more specific with the steps you took up until that point..

thanks rockleeman.. ill try it
