One of regular reader asks a question:
My website powered by Lighttpd web server. I’d like to block Wget useragent for entire my domain.com site except for /downloads/ url section. How do I configure lighttpd?
You need to use $HTTP filed useragent and url combination. Just open your lighttpd.conf file and append code as follows.
Lighttpd block useragent wget configuration
# vi /etc/lighttpd/lighttpd.conf
Append config directive as follows:
$HTTP["useragent"] =~ "Wget" { $HTTP["url"] !~ "^/download($|/)" { url.access-deny = ( "" ) } }
Where,
- $HTTP[“useragent”] : Match on useragent i.e. Wget
- $HTTP[“url”] : Match on url section such as /download/*. If there are nested blocks, this must be the most inner block.
- =~ : Perl style regular expression match
- !~ : Perl style regular expression not match
Just restart the webserver, enter:
# /etc/init.d/lighttpd restart
Now user can run wget on http://domain.com/download/* urls but not on http://domain.com/file.html or http://domain.com/dir/file
