Unable to Delete Workflow Models through a Dispatcher fronted CQ5 Author instance

Symptoms

You are accessing a CQ5 author instance through the Day Dispatcher web module and you are unable to delete workflow models.

Steps to reproduce:

1. Log into CQ author instance (make sure you're traversing through the dispatcher)
2. Create a new workflow (title = workflowToDelete)
3. Note the workflow was successfully created
4. Right click on the workflow you just created and click 'delete'. Click 'yes' to confirm.
5. Note the error message box: ERROR 'Could not delete workflow model!!'

Resolution

Add the following headers to your dispatcher.any file configuration in the /clientheaders section: x-http-method-override, x-requested-with

{{
/clientheaders
{
  ...
"x-http-method-override"
"x-requested-with"
}
