Tip for Apache - Block viewing a page or a stream to an IP via RewriteRules

[Nicholas Easter]

Here is a little trick to block an IP address to access a certain content with rewriting rules Apache. I will take here the example of a flow, I want to block access to an RSS feed for a given IP address

Here are the rules for Htaccess in the related rewrites:

RewriteCond % {REMOTE_ADDR} ^192\.0\.10\.79$
RewriteCond % {REQUEST_URI} ^ / feed.php? Type = rss *
RewriteRule .* / Error.html [R, L]

Basically, it's:

If the IP address 192.0.10.79 is equal to

AND

If the requested page is / feed.php? Type = rss
I then redirects to the page / error.html

This trick can be handy if someone uses your feed, for example to create a "blog" without respecting the license of your content.
