RE: [squid-users] ACL based on header (iPhone)

I should have been more specific. How can I setup squid to allow ActiveSync (the mail app from the iPhone). I have what I think is the correct config, but everytime I open the mail app I just get stuff like bad password prompts and stuff.

In the logs:

1252955858.226 1 10.x.x.x TCP_MISS/401 1942 OPTIONS https://proxyowa.server.net/Microsoft-Server-ActiveSync - FIRST_UP_PARENT/owa_ssl text/html
1252955858.286 1 10.x.x.x TCP_MISS/401 1942 OPTIONS https://proxyowa.server.net/Microsoft-Server-ActiveSync - FIRST_UP_PARENT/owa_ssl text/html
1252955858.351 1 10.x.x.x TCP_MISS/401 1942 OPTIONS https://proxyowa.server.net/Microsoft-Server-ActiveSync - FIRST_UP_PARENT/owa_ssl text/html

Squid config:

acl OWA dstdomain proxyowa.server.net
acl url_allow url_regex -i ^https://proxyowa.server.net/rpc.*$
acl url_allow url_regex -i ^https://proxyowa.server.net/exchange.*$
acl url_allow url_regex -i ^https://proxyowa.server.net/exchweb.*$
acl url_allow url_regex -i ^https://proxyowa.server.net/webmail.*$
acl url_allow url_regex -i ^https://proxyowa.server.net/OMA.*$
acl url_allow url_regex -i ^https://proxyowa.server.net/Microsoft-Server-ActiveSync.*

cache_peer_access owaServer allow OWA
never_direct allow OWA

http_access allow url_allow
http_access allow OWA
http_access deny all
miss_access allow OWA
miss_access deny all

I want to have an http_access that checks to see if the request is coming from iPhone and allow access. I know the User Agent can be changed but this is a small start.

    Sure you can. The 'browser' ACL matches exclusively on User-Agent
request header and req_header ACl type can be used to match any other
request header, if that's the case.

# acl aclname browser [-i] regexp ...
# # pattern match on User-Agent header (see also req_header below)

# acl aclname req_header header-name [-i] any\.regex\.here
# # regex match against any of the known request headers. May be
# # thought of as a superset of "browser", "referer" and "mime-type"
# # ACLs.

    probably something like:

acl iphone browser -i Apple-iPhone

    and using that correctly on your http_access rules would do the job.
Keep in mind that if any other user forges the User-Agent header, which
is easily done by the way, your rules would allow those requests.
There's no way to have sure we're really dealing with an iPhone here.
