Create a FUNCTIONING .htaccess file, for use on a Linux-based server

I recently moved my website from a Test Server, onto a Live Domain Server My domain is being hosted by a Shared-Hosting service (Registrar) I have a problem with my .HTACCESS file. I am trying to configure it properly to enable certain specific actions to be taken, whenever someone visits my website on the internet. I have a working version of the .HTACCESS file, which currently has the following taken care of : (a) it removes all .PHP file-extensions (b) it takes care of INDEX files Right now, I want to add certain code to the .HTACCESS file which will do the following : it will REMOVE any and all file-paths which come after my domain name, and replace them with a string of "rubbish" characters, when displaying them in the browser's address-line. For instance, let's say that my domain name is : [login to view URL] Let's say that, under my main root folder, I have a folder called : PHP And, under this folder, I have a LOG-IN file named : [login to view URL] So, when a user wants to log in, he will see the following in his browser's address box : [login to view URL] I want to remove this. I don't want my folders and file-names to be visible. I want it to be displayed as follows : [login to view URL]*)#?(&/¤FKG?=&)=*)#?(&/¤FKG?=&)= In other words : no matter which page the user visits, the ONLY thing he can see clearly in his browser is : [login to view URL] Anything which comes after that is just a bunch of randomly-selected characters. (Please NOTE : emphasis on "randomly-selected" characters). This is all I need done. I am assuming it can be done in the .HTACCESS file. I am uploading my current .htaccess file here. I merely need someone to ADD the proper code, which will accomplish the task stated above. NOTE : this job is a minor task, obviously. But, it is a serious one. Whatever your fee may be, you will NOT get paid until I have tested the HTACCESS file you give me, and ensured that it is working! Thank you
