Disabling the Forward Proxying Feature in a Reverse Proxy Setup

A proxy server instance, when configured as a reverse proxy server, by default does not stop functioning as a forward proxy server. Such a server instance accepts and serves reverse proxy requests as well as forward proxy requests. Further configuration is required to disable the forward proxying feature. You can set up an ACL configuration that denies requests whose URI matches forward proxy format. You can use a Client directive for this purpose:

<Client uri="http://.*">
PathCheck fn="check-acl" acl="http://.*"
<Client>
.
.
.
The "http://.*" ACL can be a deny all ACL as follows:
.
.
acl "http://.*";
deny (all) user="anyone";
