The Squid Accelerator Mode had trouble me very much !
There has something about Squid trouble me some days, i couldn't resolve it, so i write to you ,could you help me ? or someone else.
that is,
I want to configure Squid (squid-2.5.STABLE10) as "Accelerator Mode",then do like these:
In my local redhat server, (IP:192.168.1.248),
1、download squid-2.5.STABLE10 then unzip and confiure it like :
-bash-2.05b# ./configure --enable-useragent-log --enable-referer-log --enable-poll --disable-internal-dns --enable-truncate --prefix=/usr/local/squid/
2、configure squid.conf:
http_port 8888
icp_port 0
hierarchy_stoplist cgi-bin ?
acl QUERY urlpath_regex cgi-bin \?
no_cache deny QUERY
cache_mem 128 MB
cache_dir ufs /usr/local/squid/var/cache 256 16 256
cache_access_log /usr/local/squid/var/logs/access.log

httpd_accel_uses_host_header on
error_directory /usr/local/squid/share/errors/Simplify_Chinese
coredump_dir /usr/local/squid/var/cache
other config paragraphs was the default of sqquid.conf , then I run squid , yes, then i can find squid
root 2613 1 0 12:06 ? 00:00:00 ./squid
nobody 2615 2613 0 12:06 ? 00:00:00 (squid)

nobody 2626 2615 0 12:06 ? 00:00:00 (unlinkd)
well, then i put a static HTML file named test.html in http://article.pchome.net/test.html ,then i visit from the local server url with http://192.168.1.248:8888/test.html
Then i run ab (Apache HTTP server benchmarking tool) like this:
-bash-2.05b# ab -n 50 -c 50 http://192.168.1.248:8888/test.html

Ok,let's continue.
Then I rewrite my PHP scripts file and send the http header infomations at the file top , like this,
<?php
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header("Expires: " .gmdate ("D, d M Y H:i:s", time() + 60 * 10). " GMT");
?>

..................
then I use the CGI variable PATH_INFO rewrite the script URL ,the original url is
http://article.pchome.net/00/00/02/90/?14,35
the new url is
http://article.pchome.net/00/00/02/90/index.phtml/14/35/index.html
then run ab visit from local squid with url:
http://192.168.1.248:8888/00/00/02/90/index.phtml/14/35/index.html
-bash-2.05b# ab -n 50 -c 50 http://192.168.1.248:8888/00/00/02/90/index.phtml/14/35/index.html
