I need to create SLA that I can use in custom objects.
If there is any solution then please let me know.

I have written a code to attach multiple attachment from vf page using forcetk.
The code is working fine when I am running the VF page individually
but when I am attaching the VF page in Salesforce Site the file is not attaching and its giving INVALID_SESSION_ID.

Is there any way to get SessionID in Salesfore Site.
Can anyone help..??
