htaccess No Folders No pages is it possible?

[inet411]

I have a site which accepts posts from other sites. Some people are abusing this by finding a certain php script and submitting to the file [mysite.com...]

I have changed thefile.php name a few times but eventually they find it.

Is there a way with htaccess so make all my folders, pages etc.. not seen in the browser.

For example no matter where anyone went on my site they would see [mysite.com...] even if they were are [mysite.com...]

I've done everything else from javascripts, frames, includes and more. If someone has an htaccess solution as described above, I would be in heaven.

Thanks for at least taking the time to read this.
