Hello Vinayak,

    There are options to add various semi-standard headers such as
X-Forwarded-For. More such options/headers can be added if needed.

For really custom headers, constant (i.e., hard-coded in squid.conf)
values and "always-add" behavior is usually not sufficient because most
applications require the values to be computed for each transaction,
received values to be deleted or appended to, etc. Most users start with
a constant header idea but eventually realize that they would be better
off with adding custom headers using ICAP or eCAP interfaces, where they
can implement header-specific logic.

Said that, the demand for a generic option to add a custom header never
goes away so I suspect it will eventually be added. If you would like to
work on the corresponding source code changes, please say so and I will
post some related notes that you can use as a starting point.

HTH,

Alex.
