Question

This particular code works on one server, but not the other. The working one has Apache2, the other Apache1. How can I make it work on both?

<IfModule mod_rewrite.c>
  RewriteEngine on
  RewriteBase /

  # SEO translation
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule ^(?:[a-z]{2}/)?.*-p-([0-9]+)$ page.php?page_id=$1&%{QUERY_STRING}
  RewriteRule ^(?:[a-z]{2}/)?(.*) $1?%{QUERY_STRING}
</IfModule>

Input URL alternatives:

• http://www.domain.com/some-fancy-title-p-10
• http://www.domain.com/en/some-fancy-title-p-10
• http://www.domain.com/sv/some-fancy-title-p-10

Answer 1

It appears ?: is not valid regexp in apache1. Avoiding it solves the problem.
