Sorry for the confusion.
Here is what we need:
We have a website with billing and support programs hosted.
www.xyzbillingsupport.com
Another website with joomla and multsites installed/setup.
www.xyzmulsitiessetup.com
We need:
To Create a new multisite remotely from xyzbillingsupport.com
However, the master and the slave sites will both be on xyzmultisitessetup.com but we just need the replication process to be remote.
May be we can do a post something like this.
xyzmulsitessetup.com/createsite.php?site_id=joe&user_id=786×tamp=15478154
Make Sense??
Thanks
