I want to create a HTML/CGI Script, so that when a user logs on, a interm file is created which keeps basic information about that user until they log off. The filename is going to be created using the username and pin number, after logoff I would unlink it, the question is, will HTML let me do this through PERL CGI and is this a security issue? I'd have to open CHMOD the directory that the file will be created in..
