Just like the title is:
Is there a way to get the authentication type of a squid proxyserver from a client in the local network?
Im using debian
UPDATE 1:
HTTP/1.1 407 Proxy Authentication Required
Server: squid/3.3.9
Mime-Version: 1.0
Date: Fri, 25 Apr 2014 17:51:25 GMT
Content-Type: text/html
Content-Length: 3305
X-Squid-Error: ERR_CACHE_ACCESS_DENIED 0
Vary: Accept-Language
Content-Language: en
Proxy-Authenticate: Basic realm="Squid Web Proxy"
X-Cache: MISS from domain.com
Via: 1.1 domain.com (squid/3.3.9)
Connection: keep-alive
I am only seeing the Basic realm line. So my Proxy only accepts Basic authentication right?
