We have problem when accesing this url: www.aeat.es It seems a problem when the web site redirects to http://www.aeat.es/wps/portal/Home?url=&channel=1af861cd949a1010VgnVCM100000 d7005a80____&ver=L&site=56d8237c0bc1ff00VgnVCM100000d7005a80____ I have checked and we can access without using the proxy. Squid logs only shows the 404 message. Any clue? Thanks in advance Angel
