[TYPO3-dev] Package Loading Order - Define an Extension to be loaded before another

[Caspar Stuebs]

Hi Stephan,

thanks for your answer.

I am triyng to write an extension that catches old links from 'before a
relauch' and redirect it to the configured pages 'after the relaunch'. This
has to work with different domains, means three old domains are moved into
one new domain.
Due to that I need to be sure, that my hook to find the id is processed
before the one of realurl. If not, realurl will run into the page not found
handling.

I think the solution to use array_unshift() is good for that. Thanks for
your help.

Kind regards.
Caspar
