Hola, resulta que cuando quiero darme de alta o registrarme de nuevo en una conocida web española dedicada al la saga PES me pone lo siguiente ya sea utilizando el Mozilla o el Explorer:
Warning: your browser doesn't send the HTTP_REFERER header to the website.
This can be caused due to your browser, using a proxy server or your firewall.
Please change browser or turn off the use of a proxy
or turn off the 'Deny servers to trace web browsing' in your firewall
and you shouldn't have problems when sending a POST on this website.
Saludos
PD:Solo me ocurre en esta.
