I have a tricky problem with list event handlers (item checking in).. I deployed a site level feature with itemcheckingin event for sharepoint 2010.
If I access the sharepoint site using the url's defined in AAM, then event handlers work fine. But lets say any user uses a different url (by adding an entry to HOSTS file) then sharepoint does not trigger event handlers.
Is there any way to register event handlers regardless of the access url ? or am I doing something wrong while registering / configuring sharepoint ?
