How can we launch a task from a cron job under a custom domain?

Question

A Cron job runs under a domain, *.appspot.com(server name), because it doesn't belong to any particular (custom) domain.

But tasks in TaskQueue run under its parent servlet's domain, like www.example.com or xyz.abc.com.

How can the tasks be launched into a particular custom domain from cron jobs?

Answer 1

"use the cron job to hit a URL on the custom domain (with parameters if needed) and push new items into the queue"

Answer 2

The actual domain name used to launch the cron job or task doesn't matter. As long as mydomain.com points to myapp.appspot.com, it will be handled by the same GAE handler. You shouldn't ever need to check the domain name of the request. So just launch the task from cron job and don't worry about it.
