Re: [squid-users] HTTP Accelerator

Hello Preston Garrison,

        Please look in to the squid.conf file for the following directives
for any
changes that may have happened.You can find the squid configuration file in
the default location /usr/local/squid/etc/squid.conf. Verify the below
specified
directives are there in your squid.conf to made squid in accelerator
mode.In the
httpd_accel_host or httpd_accel_port, the IP address specified must be the
IP
of your application server and port should be the your web application
server port, In case that is changed make the changes here and restart the
squid .

The Basic configuration for squid in accelerator mode are as follows,
http_port: where the squid listens for
the incoming request.
httpd_accel_host: backend server(your
application
server IP address)
httpd_accel_port Port in which the application
server runs
httpd_accel_single_host: If it act as webaccelerator for a
single host set it to on(in your case let it be on)
httpd_accel_uses_host_header Let this one off.

Ex:
                 http_port 80
                 httpd_accel_host 172.16.1.115
                 httpd_accel_port 80
                 httpd_accel_single_host on
                 httpd_accel_uses_host_header off

Note: As both squid and webserver are not in same box ,you can use 80 as
above for both port .

And also verify other rules that you've set in the squid.conf are
correct,b'coz
some tags are repeated with different values .
ex...
1)cache_access_log /dev/null
cache_log /usr/local/squid/logs/cache.log
cache_store_log /dev/null

acl all src 0.0.0.0/0.0.0.0
2)http_access allow all and http_access deny all ...
