HTTP Traffic Sniffer

I am Looking to build a simple application to monitor http traffic. I will need the source codes, the language should be preferably c#, Visual Basic will also be accepted if it's not too hard to convert it to C# (source should be in form of ms visual studio project). Requirements/Features: Must work without installing anything like wincap or other softwares.(Note: Easyhook and other dependencies may be allowed but ask me 1st) Must work on most computers using windows.(Windows XP/Vista/7 32/64 bits.) Must be able to parse the url from the http header and then redirect based on conditions. Must Work for most browsers(Firefox, IE, Optional:Opera, Chrome) Must be able to run all the time. Must use forms (no console). I looked into this quite a few times and from what i've been told there's a few ways this can be accomplished, one is by hooking DnsQuery_A/W/UTF8 (there are 3 different ones) in dnsapi another is hooking connect()/gethostname() in Winsock and the last way I seen is by creating a proxy.
