Sorry let me elaborate this .
Squid is acting as Transparent Proxy
User A browses on HTTP say http://abc.com

I want to Add a additional Header
HTTP_X_PROFILE=Profile of Customer
How can I add this ? Because based on the IP address , I need to
Query LDAP / RADIUS / AAA Server and Fetch the User Profile Dynamically
and add a new header with dynamic fetched value .
Hope this clarifies ..
Okay. Thank you.
You need a external_acl_type helper which recieves the %SRC parameter
and returns the profile details.
In 3.4 (beta) series the annotation feature is a far better way to do
it. The helper returns a custom key=value which is targeted at the headers.
That key-value can be added as the header contents with
add_request_header and the %{key-name}note format option.
Something like this:
external_acl_type profile %SRC /path/to/helper
acl profiler external profile
http_access allow profiler
request_header_add X-Profile %{profile}note
The helper returns this: OK profile="profile details"\n
Alternatively, you can also do it in 3.3 version where the
add_request_header is present, but that version is stuck with the
logging feature to return detais from the helper. Like so:
OK log="profile details"\n
and the generic %ea token has to be used in request_header_add:
request_header_add X-Profile %ea
NP: older versions of Squid lack even the request_header_add feature so
it is not possible to do it without ICAP/eCAP adaptation.
