I limit the maximum file size an employee can download to our network

My problem is that I would like to differentiate between the status
code 403
that comes from a target website that does not allow access at all to
download
a specific file and to the intentional 403 that is generated from
Squid
because the file size exceeds the limit we set.
The reason is that I want to display the user a message like "The
target
website does not allow access" and "You have requested a file to
download that
is too large. Please contact the IT department". I was thinking that
the 413
is useful for that.
Apart from the minor detail that 413 applies only to *request* size.
Client software can get confused if the zero-length *request* body on a
GET is "too big" for example. Yes, I have looked into this.
Is there a way to change the status code/message when a user hits the
reply_body_max_size and differentiate that case? Is there any other
workaround?
If your Squid is new enough (3.2 beta) you can use deny_info to set the
status code delivered.
I recommend picking some high unused number for this. 49x or such until
somebody writes up a IETF specification for this type of usage and
allocates a code.
