dns

I'm connecting to some websites through socks proxy server. In my case its very good to implement dns cache, so proxy don't need to resolve website's ip address. So, I performed DNS lookup, but don't know where to supply IP address. mySocket.Connect uses proxy's ip address so it isn't right place. I tried to place it in http header GET http://11.22.33.44/index.html HTTP/1.1 - this doesn't work (even in browser) since website is on virtual hosting. It seems that Host header is right place for resolved ip address. Am I right? Will proxy resolve host name (since it's still there in GET header) or not?

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
