Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

We have a website where the URL looks something like, www.example.com/about.smart.html

( "smart" being selector added on the app server based on the useragent if its a smart phone device)

We need to redirect the page to 404 if the URL is changed by the user as like below:

  1. www.example.com/about.abc.xyz.smart.html
  2. www.example.com/about.smart.abc.html

I tried with the below rule, but this redirects to 404 only for 1) and not for 2)

RewriteCond  %{REQUEST_URI} !^(.*)(-)\.html$
RewriteRule (.*)\.(.*).smart.html$ - [R=404,L] 

Any pointers on this would be of great help.

watch out for those dots, \.(.*).smart will not match the about.smart in #2 –  Tom McClure Oct 4 '12 at 23:31
Thanks Jon, but again now Behavior is reversed. #2 redirects to 404 but #1 doesn't. Any other suggestions? –  user1720607 Oct 5 '12 at 5:52
@user1720607 The first URL redirects to a 404 when I put those rules in a blank htaccess file and request /about.abc.xyz.smart.html –  Jon Lin Oct 5 '12 at 17:48
Thanks Jon, yes it worked. I had to rearrange existing rules. –  user1720607 Oct 9 '12 at 4:59
