  1. Edit conf file: /etc/lighttpd/lighttpd.conf
  2. Enable mod_expire and mod_compress.
  3. Expire static files set for 3 days:
    $HTTP["url"] =~ "\.(js|css|gif|jpg|png|ico|txt|swf|html|htm)$" { expire.url = ( "" => "access 3 days" ) }
  4. Compress mime types:
    compress.cache-dir         = "/var/cache/lighttpd/compress/"
    compress.filetype          = ("text/plain", "text/html", "text/css", "text/xml", "text/javascript")
  5. Cleanup the compressed cache via daily cron script:
    #!/bin/bash
    # lighttpd_cache_clean
    # Clean cache stored at /var/cache/lighttpd/compress
    # Place in /etc/cron.daily

    # Cache dir path
    CROOT="/var/cache/lighttpd/compress"

    #Deleting files older than 3 days
    HOURS=72

    # Lighttpd user and group
    LUSER="lighttpd"
    LGROUP="lighttpd"

    # start cleaning
    /usr/sbin/tmpwatch --mtime ${HOURS} ${CROOT}

    # if directory missing just recreate it
    if [ ! -d $CROOT ]
    then
            mkdir -p $CROOT
            chown ${LUSER}:${LGROUP} ${CROOT}
    fi

    exit 0
  6. Create the cache directory and update permissions:
    mkdir -p /var/cache/lighttpd/compress
    chown lighttpd:lighttpd /var/cache/lighttpd/compress
  7. Restart lighttpd.
