In Drupal 6 this can be done with core modules like this:
- enable Trigger module
- add an action
- add advanced action at the bottom and choose “Redirect to URL”
- use description regardless of how you will use it but rather describing what this action does; e.g. “redirect to start node”
- as URL apply “node”
- set-up the appropriate trigger
- from the drop-down list at “Trigger: After a user has logged in” select your new action from just now
- log out and back in again to test it
Note: In the links provided you need to change saying “your-domain-path-to-drupal” by your actual domain name (or navigate as usual if you now where to find the settings pages in Drupal 6) to make it http://example.com/admin. If you happen to have clean urls disabled you might know already that you also need to prefix the admin path by “?q=” so it alltogether looks like this: http://example.com/?q=admin
