squid+apache = good cache, protection from ddos

December 10th, 2009

just reconfigured my webserver runing on localhost why?
read under ….
1. what is best practice to have good performance ? – CACHE ! which means if your webserver know where is file(image,song, swf .. etc) located on hard drive and already opened it ones with another customer, why it must be opened second time ? with webserver ? it will make a good lick on performace site if youre runing heavy site with lot of pictures.
2. what is the best program for working on many simple GET/POST/CONNECT requests ? – Squid – caching proxy server runing under Linux and using all power of linux fs for making cache and make it fast
i just made a hibrid combination on my squid ( runing on 80 port) and apache (runing on 127.0.0.1:80).
here is simple config of my squid
http_port 62.75.250.93:80 transparent

icp_port 0

htcp_port 0

hierarchy_stoplist cgi-bin ?

acl QUERY urlpath_regex cgi-bin \?

no_cache deny QUERY

always_direct allow all

never_direct deny all
on apache you just need to change Virtual host and LISTEN to 127.0.0.1 (remeber to add your host under localhost at /etc/hosts)
max_con – is a acl that will not allow more then 20 concurrent connections from 1 IP – good method for protecting from http get and syn flood attacks
