Creating Steam Event using Sockets

Question

A while back I wrote a game plugin using sockets that automatically sent invites to a steam group using a game plugin. I am attempting to do the same thing except to create events from game instead of having to login to the steam panel.

Here is what I got from Wireshark when creating the event...

GET: http://teamras.net/get.png

For some reason it is not creating the event though. This is what my code looks like for doing it and what the actual string looks like

www.steamcommunity.com/groups/tf2rocketarena/eventEdit&action=newEvent&name=testtitle&type=ChatEvent&notes=hellothar&startDate=MMFDDFYY&startHour=12&startMinute=00&startAMPM=PM&timeChoice=quick&eventQuickTime=now&tzOffset=-18000
