Configuration for Caddy Web Server server

If you are using a Caddy Web Server that does not support .htaccess rules, additional configuration is required for the Xilifox Image Optimizer plugin to work properly.

• Step 1. #

  Start an SSH connection to your website or forward this instruction to your server administrator.

• Step 2. #

  Go to the host configuration directory using the command:

  cd /etc/caddy

  Use the command to edit the configuration file:

  nano Caddyfile

• Step 3. #

  In the configuration file, find the block responsible for your domain and add the following rules in it:

  # BEGIN XIO
header /wp-content/*/*.jpg Cache-Control "private"
header /wp-content/*/*.jpeg Cache-Control "private"
header /wp-content/*/*.png Cache-Control "private"
header /wp-content/*/*.webp Cache-Control "private"
 
@acceptsAvif {
    header Accept *image/avif*
    path_regexp avif ^/wp-content/(.+)/(.+)\.(jpg|jpeg|png|webp)$
}
@acceptsWebp {
    header Accept *image/webp*
    path_regexp webp ^/wp-content/(.+)/(.+)\.(jpg|jpeg|png)$
}
 
handle @acceptsAvif {
    @hasAvif file /wp-content/uploads-xio/{re.avif.1}/{re.avif.2}.{re.avif.3}.avif
    rewrite @hasAvif /wp-content/uploads-xio/{re.avif.1}/{re.avif.2}.{re.avif.3}.avif
}
handle @acceptsWebp {
    @hasWebp file /wp-content/uploads-xio/{re.webp.1}/{re.webp.2}.{re.webp.3}.webp
    rewrite @hasWebp /wp-content/uploads-xio/{re.webp.1}/{re.webp.2}.{re.webp.3}.webp
}
# END XIO

  Please remember to:

  • add rules in the block responsible for your domain
  • if you have several blocks responsible for your domain (e.g. separate for HTTP and HTTPS), add rules in all blocks
  • add these rules before other directives in the block

• Step 4. #

  Restart the Caddy server using the command:

  service caddy restart

• Step 5. #

  That’s all! Our plugin will work properly.
