Howto Block all USER_AGENT except a custom one


Recommended Posts


I'm trying to have a web page accessible only from inside an android app. I can make the app to provide a custom user agent. For example 

Mozilla/5.0 (MyAPP) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/ Mobile Safari/537.36

I need to edit the .htaccess file to deny all visitors, except the one with the "MyAPP" string in its user agent.

I've tried using this:

RewriteCond %{HTTP_USER_AGENT} ^.*MyAPP*$
RewriteRule .* - [L]
RewriteRule .* http://mydomain.com/error.html [R,L]

but i get all traffic sent to error.html, including the one from my app.

What am I missing here?

I'd try this…



RewriteCond %{HTTP_USER_AGENT} !MyApp
RewriteRule ^.* http://mydomain.com/error.html [R=302] 


I think the most critical thing you were missing was the ! at the beginning of the pattern. That ! says "not"… You were matching the string, you needed to match all the ones that don't match the string. I think L is redundant if there's a redirect. And I always do R=302 (or R=301) so I know exactly what type of redirect is being done.
