It’s only to add the possibility to chose to remove from mikrotik webproxy http header
HTTP_VIA 1.1 <public_ip_on_mikrotik_wan> (Mikrotik HttpProxy)
HTTP_X_PROXY_ID <routerboard_serial_number>
HTTP_X_FORWARDED_FOR <true_ip_of_the_computer>
for not reveal to the site opened the use of webproxy and the other informations…
Some site like google treat that traffic as “bot” traffic…
