Rule Layering

Overview

Rule Layering is a specific configuration where you can use the Rules from a Tag Group layer with the Default Responses of the Tag Code layer.

This can be useful if you want to set a generic Rule across all the Tag Codes within a Tag Group but want to set individual URLs on each of the Tag Codes themselves.

How to use Rule Layering

To use Rule Layering, you should have configured your Rules at the Tag Group level. In one (only one) of your Rule Responses, you add :

{tagcodedr}

At the Tag Code level, you need to enter your Default Destination URL for that Tag Code.

Under normal use case, ixkio would not process Tag Group Rules if a Default Response had been entered at the Tag Code level - the Tag Code Response would overrule.

However, with Rule Layering, ixkio processes the Tag Group Rules instead and the uses the Tag Code URL where you have used {tagcodedr}

Rule Layering Example

Let's assume we have a configuration where you want to prevent all non-registered users from being redirected to a Tag Code URL. In this instance, each of our Tag Codes has it's own URL.

We create a Ruleset at the Tag Group level like this :

Where a Not Registered User would be directed to Seritag and therefore Registered Users would pass through to the Default URL. For this Default URL, we've entered the Rule Layering code {tagcodedr}

At the Tag Code level, we will enter our Default URL as :

Normal Process

Under normal ixkio process, as the Tag Code Ruleset Default URL is configured, ixkio would use this and ignore the Tag Group Rules, however...

Rule Layering Process

When Rule Layers are enabled (by using the {tagcodedr}), then ixkio uses the Tag Group Rules first. In this example, a Non-Registered User would be directed to Seritag. A registered user would pass through to the Tag Code URL, which in this case would be ixkio.

When to use Rule Layering

Generally, when you are entering specific, unique URLs for every Tag Code but want a global Ruleset to apply to them all.

Without Rule Layering, you would need to add Rules to each and every Tag Code. With Rule Layering you can have a global generic Ruleset but still allow each Tag Code to have it's own URL.

Note that there are often alternative ways to do this if you aren't adding specific full URLs to each Tag Code - for example, adding just the unique part as a CUID or Tag Name on each Tag Code and then using Subtags at the Tag Group Rule level.
