Just a quick reminder to myself, so that I can forget about it...
Fiddler can act as a man-in-the-middle and decrypt SSL traffic, but then System.Net.Security rightfully complains about an invalid remote certificate ("The remote certificate is invalid according to the validation procedure."). This results in a System.Net.WebException "The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.".
To prevent this from happening:
ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };
Just be sure to not include this in production code :-)
Two weeks ago, an ex-colleague asked me to take a look at a problem that he and his team had encountered. They tried using a System.Uri with URL-encoded slashes, but those slashes kept ending up unencoded in the resulting URI:
Uri uri = new Uri("http://somesite/media/http%3A%2F%2Fsomesite%2Fimage.gif");
Console.WriteLine(uri.AbsoluteUri);
// Output: http://somesite/media/http%3A//somesite%2Fimage.gif
That's a totally different URL, which the target server refuses to process.
I was sure that they must have overlooked something, and that there would be some way to tell the Uri constructor to leave all encoded characters as-is. But no, it does not seem possible; dots and slashes are always decoded. I find that quite surprising, so if anyone can point me to an official solution, I'd be much obliged.
In the mean time, a reflection-based hack, courtesy of Reflector and the .NET Reference Source:
static class UriHacks
{
// System.UriSyntaxFlags is internal, so let's duplicate the flag privately
private const int UnEscapeDotsAndSlashes = 0x2000000;
public static void LeaveDotsAndSlashesEscaped(this Uri uri)
{
if (uri == null)
{
throw new ArgumentNullException("uri");
}
FieldInfo fieldInfo = uri.GetType().GetField("m_Syntax", BindingFlags.Instance | BindingFlags.NonPublic);
if (fieldInfo == null)
{
throw new MissingFieldException("'m_Syntax' field not found");
}
object uriParser = fieldInfo.GetValue(uri);
fieldInfo = typeof(UriParser).GetField("m_Flags", BindingFlags.Instance | BindingFlags.NonPublic);
if (fieldInfo == null)
{
throw new MissingFieldException("'m_Flags' field not found");
}
object uriSyntaxFlags = fieldInfo.GetValue(uriParser);
// Clear the flag that we don't want
uriSyntaxFlags = (int)uriSyntaxFlags & ~UnEscapeDotsAndSlashes;
fieldInfo.SetValue(uriParser, uriSyntaxFlags);
}
}
