Maybe I am searching for the wrong terms, but I can't seem to find anything on this.

The web pages are created dynamically and written to htdocs. What can be done to prevent somebody else from viewing the dynamically created pages by either guessing the file or doing a wget?

Can the pages be removed immediately after viewing somehow?

Better yet, is there a way to avoid writing the html file to htdocs and directly stream the page to the browser? I believe in the past we would write directly to the port, but when we started using frames that was no longer an option.

The web server being used is Apache.

Thanks in advance for any advice.

A CGI generating a dynamic page that should only go to one user just writes it to stdout, not to a file. The server returns it as the response to that one http POST request and it is not saved anywhere. Responses to a GET request may be served from cached copies. Whether it's an iframe or the root does not matter.
