Re: [squid-users] How to determine if URL in HttpRequest is an Ip address

We are using squid 3.1.6 and every time i access a IP Based URL, i get
1 for GetHostIsNumeric(). There is a limitation from client for
upgradation of the release :(

Searched the net and found that IsAnyAddr() had bugs and Address.cc in
ip was modified.

Applied the patch and modified the functions IsAnyAddr to

bool
Ip::Address::IsAnyAddr() const
{
    return IN6_IS_ADDR_UNSPECIFIED(&m_SocketAddr.sin6_addr) ||
IN6_ARE_ADDR_EQUAL(&m_SocketAddr.sin6_addr, &v4_anyaddr);
}

IsIPv4() to

bool
Ip::Address::IsIPv4() const
{
    return IN6_IS_ADDR_V4MAPPED( &m_SocketAddr.sin6_addr );
}

IsIPv6 to:

bool
Ip::Address::IsIPv6() const
{
    return !IsIPv4();
}

Still i keep on getting 1 for IP Based urls.

Please suggest.

Regards
Sachin
