Alright Googler Groupers!

I've searched high and low and tried everything I care to, so I'll see
what the masses can conclude! I'm making both UPS and PayPal calls and
both of them *occaisionally* throw this error. Please help!

The error I receive is :

"The underlying connection was closed: Could not establish trust
relationship for the SSL/TLS secure channel"

The inner exception is:

"The remote certificate is invalid according to the validation
procedure"

My web.config has:

<system.net>
    <settings>
        <servicePointManager checkCertificateName="false"
checkCertificateRevocationList="false"/>
    </settings>
    <connectionManagement>
        <add address="*" maxconnection="12"/>
    </connectionManagement>
</system.net>

My Global.asax has:

ServicePointManager.CertificatePolicy = new CertificatePolicy();
ServicePointManager.ServerCertificateValidationCallback = new
RemoteCertificateValidationCallback(ValidationCallBack);

My CertificationPolicy class looks like:

public bool CheckValidationResult(ServicePoint sp, X509Certificate
cert, WebRequest req, int problem)
{
    return true;
}

And finally, my code is:

HttpRequestHandler http = new HttpRequestHandler(connectionURL);
string response = http.POST(stuffToPost);
