I'm trying to rewrite a filename based on the server's domain.

This code below is wrong / not working, but illustrates the desired effect.

<If "req('Host') != '*.mydevserver.com'">
  RewriteRule "^/robots\.txt$"  "robots-staging.txt"    [R]

Desired effect is this htaccess will point to a different robots.txt depending on if it's on staging (wildcard subdomain) or not.

Example usage:

http://client1.devsite.com/robots.txt rewritten to

http://client2.devsite.com/robots.txt rewritten to

https://client.com/robots.txt not rewritten


I found my own answer. This works as desired.

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    RewriteCond %{HTTP_HOST} ^(.*)?mydevserver(\.com)
    RewriteRule ^robots\.txt$ robots-staging.txt [NS]

    You could simplify your _CondPattern (^(.*)?mydevserver(\.com)) to mydevserver\.com (no need for the optional capturing sub patterns and anchors if you are just checking for "mydevserver.com"). You should probably include the L flag in case you add more directives. – MrWhite Nov 18 '17 at 16:01
