Exclude pages from super-cache

No, it’s not possible to do that. You can exclude pages, but they’ll never be cached then.

wp-o-matic does not work with wp-super-cache.

I want to exclude the wp-o-matic cron page from wp-super-cache i.e.-
/wp-content/plugins/wp-o-matic/cron.php?code=804950f1

How can I do that ?

Do you have “wp-.*.php” in your rejected URI list? That should do it.
