Browser not automatically redirecting for 301/302 responses when AutoRedirect is 'true'

[MChartier]

I'm new to SimpleBrowser, but I'm having trouble getting started by following the provided examples because the Browser object does not appear to be automatically redirecting as expected.

var browser = new Browser();
browser.UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US) AppleWebKit/534.10 (KHTML, like Gecko) Chrome/8.0.552.224 Safari/534.10";
browser.AutoRedirect = true;
browser.Navigate("http://en.wikipedia.org");
if (browser.LastWebException != null)
{
     // This line is always hit
    return null;
}

Instead of automatically redirecting on a 301 or 302 response as configured, the LastWebException is populated with a WebException related to a 301 TLS Redirect. I would expect the Browser instance to automatically redirect to "https://en.wikipedia.org/wiki/Main_Page".

Bug or user error? If the latter, what should I be doing differently?

This is a bug, but it's already reported as Issue #198. SimpleBrowser is written using .NET Framework 4.0. .NET Framework 4.0 does not support TLS 1.2, which is what Wikipedia requires (and increasing number of well-maintained web sites require). Therefore, when the 301 or 302 redirect occurs and the browser is redirected from http to https, an exception occurs.

You have two options:

1. Upgrade the SimpleBrowser project to .NET Framework 4.5. (Then submit that change as a pull request as a solution for Issue #198.)
2. There is a line of code to add to the SimpleBrowser static constructor in Issue #198. Add that line of code, then recompile SimpleBrowser. (This is a bit of a hack, and requires that your project using SimpleBrowser is .NET Framework 4.5 or better.)

Thanks for the quick reply pointing me in the right direction.

I decided to do the .NET 4.5 upgrade today. I will be checking it in shortly.
