I've got an other problem, each web server use cookies methods and I need to rewrite the Cookie path too. I didn't find a solution on the FAQ. example : Web server1 >> squid : HTTP/1.1 200 OK Set-Cookie: cookie=[Token]; Path=/app1 squid >> user: HTTP/1.1 200 OK Set-Cookie: cookie=[Token]; Path=/serv1/app1 Is it possible ?
