[squid-users] R: [squid-users] Example of squid accelerator

>you need at least one of defaultside=

Internet users reach my company site on IP address 1.2.3.244 where they find
a certain section which contents 4 icons.
These 4 icons (corresponding to 4 towns) links respectively to

http://1.2.3.4/LicroPS.sav.1/mkLicro.do?codCenter=22101
http://1.2.3.4/LicroPS.sav.1/mkLicro.do?codCenter=22102
http://1.2.3.4/LicroPS.sav.1/mkLicro.do?codCenter=22103
http://1.2.3.4/LicroPS.sav.1/mkLicro.do?codCenter=22104

User can decide what link is interesting, according to town to whose He
belongs, so there is no default page.
Can I describe in this way ?
http_port 1.2.3.4:80 accel vhost

>Don't use dst there, use dstdomain instead matching the allowed
>sitenames/hostnames

What's the reason ? Pheraps because with dst directive Squid looks up dns
for IPAddress from the domain-name, which is in request header.
I could having, for specific reasons, some sites which are not registred in
dns even if this time is not my case.

you need at least one of defaultside= or vhost as well.. if not Squid
doesn't know how to read the requests.. Most people want to use vhost
there.

> cache_peer A.B.C.D. parent 8080 0 no-query originserver name=PSAccel

ok.

> acl MySite dst 1.2.3.4
> http_access allow MySite
> cache_peer_access PSAccel allow MySite
> cache_peer_access PSAccel deny all

Don't use dst there, use dstdomain instead matching the allowed
sitenames/hostnames.

The browser will send that as

GET /LicroPS.sav.1/mkLicro.do?codCenter=22101 HTTP/1.1
Host: 1.2.3.4
[more headers]

vhost makes Squid use what is in the host header when building the
requested URL.

defaultsite specifies explicit what site name:port to use when
reconstructing the requested URL. Also used as fallback if there is no
Host header.
