Misc

Highlights include: Support for automatic decompression via GZip/Deflate, more aggressive disposal of response messages, rewrite of cookie handling from dictionary to cookiecontainer, debug log of also timed out messages and more.
We sacrifice the performance and scalability of single HttpClient doing the work for being less error prone on eventual steam fuckups (CookieContainer can adapt to always changing structure)

+NetHook2
+===================
+
+This tool is used for reverse-engineering of Steam client. It's capable of hooking and recording network traffic sent/received by the client. If you're not trying to implement missing SK2 functionality in ASF, then please do not proceed.
+
+1. Launch Steam client
+2. Execute ```hook.bat```
+3. Reproduce the functionality you're trying to add
+4. Execute ```unhook.bat```
+5. Use ```NetHookAnalyzer2.exe``` for analyzing recorded log (which can be found in your Steam directory)
+
+- Source of the ```NetHook2.dll``` can be found **[here](https://github.com/SteamRE/SteamKit/tree/master/Resources/NetHook2)**
+- Source of the ```NetHookAnalyzer2.exe``` can be found **[here](https://github.com/SteamRE/SteamKit/tree/master/Resources/NetHookAnalyzer2)**
+
+===================
+
+There is absolutely no guarantee that this will even work for you, not to mention the consequences from hooking the external DLL into steam client. You're on your own.
