Hi Eliezer
Thanks, but i have another question. we are force to know about mirror
address for sf.net? or for example filehippo.com?
or is it not important?
and can you explain me about nginx variable used in site.conf? for
example $host, $uri, $request_uri. i used same method with apache and
with intelligentmirror 3 years ago.
thanks,

Hi
I have a problem with squid refresh_pattern. i used regex on
refresh_pattern and every exe file for example cached and then clients
can download it with high rate. but when someone download from some
website(for example mozilla or filehippo) , they redirect to different
url but the same XYZ exe file. for example firefox-version.exe cached
to the disk but when another clients send new request, it redirect
automatically to different url for downloading same firefox. how can i
configure squid for this condition?
By altering your regex pattern to work with both URL. Or adding a
different pattern to match the alternative URL.
if you have some examples for patterns it can help simplify the problem.
i think i do understand and if so i just recently implemented cache
for sourceforge using nginx.
as of filehippo it's different.
let say i am downloading one file of total commander the links from
couple of servers will be:
http://fs31.filehippo.com/7077/9965e6338ead4f6fb9d81ac695eae99a/tc80beta24.exe
http://fs30.filehippo.com/6386/9965e6338ead4f6fb9d81ac695eae99a/tc80beta24.exe
http://fs33.filehippo.com/6957/9965e6338ead4f6fb9d81ac695eae99a/tc80beta24.exe
so there is a basic url match pattern but you must break the path and
it's a bit complicated.
but as for source forge i will share the method i have used.
the following is the nginx site.conf content:
#start
server {
listen 127.0.0.1:8086;
location / {
root /usr/local/www/nginx_cache/files;
try_files "/sf$uri" @proxy_sf.net;
}
location @proxy_sf.net {
resolver 192.168.10.201;
proxy_pass http://$host$request_uri;
proxy_temp_path "/usr/local/www/nginx_cache/tmp";
proxy_store "/usr/local/www/nginx_cache/files/sf$uri";
proxy_set_header X-SourceForge-Cache "eliezer@xxxxxxxxxxxx";
proxy_set_header Accept "*/*";
proxy_set_header User-Agent "sourceforge Cacher (nginx)";
proxy_set_header Accept-Encoding "";
proxy_set_header Accept-Language "";
proxy_set_header Accept-Charset "";
proxy_set_header Cache-Control "";
access_log /var/log/nginx/sf.net.access_log;
}
}
#end of nginx site.conf
#on squid.conf i used:
acl sfdl dstdom_regex (dl\.sourceforge\.net)$
cache_peer local_sf parent 8086 0 no-query no-digest proxy-only
cache_peer_access local_sf allow sfdl
cache_peer_access local_sf deny all
never_direct allow sfdl
never_direct deny all
cache deny sfdl
cache allow all
#on the hosts file i added:
127.0.0.1 local_sf
#done
the mail problem with nginx as a proxy that it will in any case will
download the full file from the source.
means if your client abort the download it will still download the
file as far as i remeber.(not 100% sure if what caused it was squid or
nginx).
i also used nginx for other sites that stores images such as
imageshack.us with almost the same method cause it seems like nginx
will serve the files very very fast and because of the huge amount of
objects i spared from squid index file to store the objects
information on the images.

NOTE: refresh_pattern has nothing to do with where squid caches the
object or where it fetches from. Only how long cacheable things get
stored.
