[squid-users] proxy.pac exclude one host:port

I've run into an issue with one site. I need to exclude it from from proxy.pac. The problem is the site is in the format http://example.com:443 and I have been unsuccessful in excluding it.
Here a few snippets from my proxy.pac that I've tried.

if (url.substring(0, 5) == "http:") {
    if (dnsDomainIs(host, "example.com"))
        return "DIRECT";

####
if (url.substring(0, 6) == "https:") {
    if (dnsDomainIs(host, "example.com"))
        return "DIRECT";

####

    if (dnsDomainIs(host, "example.com"))
        return "DIRECT";

####
    if (shExpMatch(url, "http://example.com:443*"))
        return "DIRECT";

####

    if (shExpMatch(url, "http://example.com*"))
        return "DIRECT";

####

Unfortunately I have been unable to exclude it. I can't seem to get the right mix of http over 443. Is there a function like if (url.port = 443)? I have not been able to find anything that looks at the port.

Any help would be appreciated.
