Hiding robots.txt from being visible though a browser

[Swapna]

Hi guys,
I want to know if there is any way to block the robots.txt file from being viewable through browser. Of course, the search engine bots must not face any hindrance in reading the robots.txt file, in the process of hiding it.

My site for medical transcription services has got a lot of pages that are used by the in-house sales team to update client testimonials, write articles etc., all without any login or authentication. Such pages, for our interest, better be blocked from search engines and remain out of sight of all external users.

Awaiting a positive response..

You can try to detect the type of the browser and hide robots.txt in some cases. But visitors can easily switch UserAgent in their browsers to GoogleBot, for example. Furthermore, you can try checking visitors IP. Anyway, these tasks sum up into a pretty advanced cloaking script.

I would recommend you to simply add the authentication to your "secret" directories.
