Htaccess help please

Any thoughts on how this simple task can be done?
This:
example.com/index.html?domain=google.com

to be this:
example.com/google.com

There is one solution but don't know if it is working or not. Of course using rewrite mod and all functions what one server can do.

 

If there is a solution, why haven't you tried it ?

RewriteEngine On
Options +FollowSymlinks

RewriteRule ^(.*)$ index.html?domain=$1

Code (markup):

 

rewrite mode is the best solution
@J Bin
thanks for the htacess rule

 

Oh I have this also in htaccess:
RewriteEngine On
RewriteRule ^(.*)\.html $1\.php

So it shows "Not Found" error. You see what I'm talking about?

 

You may need to alter your htaccess file by adding a base url, for example

after

RewriteEngine On

Code (markup):

add

RewriteBase /

Code (markup):

...and if that cures the initial problem, then simple add your solution ?
