Apache 2 block url such as example.com/?admin

Question

Please can you tell me in Apache2 how I can restrict a url to my IP address when the url is generated as a script. For example:

example.com/?admin 

I have tried Location Match but no joy:

<LocationMatch /?admin>
    Order Deny,Allow
    Allow from [MY IP]
    Deny from all
</LocationMatch>

Answer 1

You could use mod_rewrite to match the %{QUERY_STRING} and disallow anything that's not empty, unless it's from your IP. Check the wiki for examples.
