Forcing a variation to run based on different url parameters
There are a couple ways you could approach this:
1) You can use our force bucket feature and add code on your page that looks at the URL and then forces the visitor into the appropriate variation.
2) You could use 1 variation that uses an if function to execute different sets of variation code. For example, if the URL contains "newsletter", execute these changes, if the URL contains "banner", execute these changes.
Do any of these suggestions sound like they might work @CouchPsycho ? Let me know if you want some more details on any of the above
