Edit conf file: /etc/lighttpd/lighttpd.conf
Enable mod_expire and mod_compress.
Expire static files set for 3 days:

$HTTP["url"] =~ "\.(js|css|gif|jpg|png|ico|txt|swf|html|htm)$" { expire.url = ( "" => "access 3 days" ) }
Compress mime types:

compress.cache-dir = "/var/cache/lighttpd/compress/" compress.filetype = ("text/plain", "text/html", "text/css", "text/xml", "text/javascript")
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
Create the cache directory and update permissions:

mkdir -p /var/cache/lighttpd/compress chown lighttpd:lighttpd /var/cache/lighttpd/compress
Restart lighttpd.
