We are in need of some jQuery code which will emulate the process Facebook uses to verify Wall Posts.
For our brief experiments, it seems that a cookie is set at each stage of interaction with the Composer/Publisher component, and then these cookie values are appended to the final request and verified on the server.
So the code you will create needs to recreate this process and emulate it.
We are creating tools for our own internal use, so we will be injecting this script into the website to automate some tasks for us.
Feel free to post any questions you may have or PM me.
