LTM as a proxy asking username/password

Hi.

Thanks for your response.

I have solved my problem. I was asking for the wrong HTTP Header. I had to look for Authorization header, not Proxy-Authorization.

Finally this is my irule, and it works fine:

when HTTP_REQUEST {

    if { not ([HTTP::header exists "Authorization"]) } {
        HTTP::respond 401 WWW-Authenticate "BASIC realm=\"F5 BIGIP PROXY AUTH\""
    } else {
        set proxyauth [lindex [split [HTTP::header value "Authorization"] " "] 1]
        set username [lindex [split [b64decode $proxyauth] ":"] 0 ]
        set password [lindex [split [b64decode $proxyauth] ":"] 1 ]
        log local0. "PROXY-AUTHORIZATION HEADER IS $proxyauth, USERNAME IS $username AND PASSWORD IS $password"
        if {not ($username equals "useraaa" and $password equals "aaauser") } {
            HTTP::respond 401 WWW-Authenticate "BASIC realm=\"F5 BIGIP PROXY AUTH\""
        }
    }
}
