squid 3 -> exclude from caching

hi

I have Squid Version 3.0 PRE5 installed on debian etch.
Howto exclude an URL from caching at squid.conf ?

btw. if I allow direct do I need exclude from caching as well ?

I've added in squid.conf the following entries:

Code:

---

acl url dstdomain .mydomain.com
always_direct allow url
cache deny url

---

and hope is OK.

knows somone, is it:

Code:

---

no_cache deny myurl

---

or

Code:

---

cache deny myurl

---

at the config from squid 3 correct ?

cache deny myurl is correct, but I have an other question.

Knows someone if I use

Code:

---

allow direct

---

for an URL in /etc/squid/squid.conf, do I need also an additional entry

Code:

---

cache deny

---

to exclude from the proxy caching?
