Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://community.commandersact.com/web-container/user-manual/container-management/rules/perimeters.md). # Perimeters & constraints *Perimeters* and *Constraints* are two methods to **conditionally** fire your tags. * Under the *Perimeter* panel, tags fire if at least **one rule** is true. * Under the *Constraints* panel, tags fire if **all rules** are true. ## Variable The “**Variables**” tab allows you to create rules based on your data layer variables (external variables, internal variables, events attributes, events variables): **Condition and behavior** “**If Variable Equals**“: Tag activated if the variable equals the specified value. “**If Variable is Not Equal**“: Tag activated if the variable differs from the specified value. “**OR Condition (One Variable)**“: Tag activated if the variable equals at least one of the specified values. “N**AND Condition (One Variable)**“: Tag activated if the variable equals two or more specified values. “**OR Condition (Up To Six Possible Variables)**“: Tag activated if at least one of the variables equals the specified value. “**AND Condition (Up To Six Possible Variables)**“: Tag activated if all the variables equal all the specified values. “**Greater than condition**“: Tag activated if the variable is greater than the specified value. “**Less than condition**“: Tag activated if the variable is less than the specified value. “**If Variable Contains**“: Tag activated if the variable contains the specified value. “**If Variable Does Not Contain**“: Tag activated if the variable does not contain the specified value. “**If Variable Matches**“: Tag activated if the variable matches the specified value (regular expressions allowed: \* to match any character and ^ for “variable begins with”). “**If Variable Doesn’t Match**“: Tag activated if the variable does not match the specified value (regular expressions allowed: \* to match any character and ^ for “variable begins with”). ![](https://2673302412-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LdtBYhZj-wxWhoZaUXI%2F-LqHAJgxXBingSa2W27v%2F-LqHASu7Jt5OGjxcsZLN%2Fvariable_rule%5B1%5D.png?alt=media\&token=56d8eeae-491c-4fec-a764-c06e55888593) **In which case using “external variables” for the mapping?** When you want to create a rule based on a tc\_vars from the data layer implemented on your website. Example: your technical team has implemented an env\_template variable, and you want to create a rule based on it: ![](https://2673302412-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LdtBYhZj-wxWhoZaUXI%2F-LqHAJgxXBingSa2W27v%2F-LqHAXO57WR-_uhWfWRr%2Fdl%5B1%5D.png?alt=media\&token=bf8f2115-f8e4-4fb1-827a-2f023780b072) **In which case using “internal variables” for the mapping?** When you want to create a rule based on a variable that you have created by yourself, from the internal variable interface. **In which case using “event variables” for the mapping?** When you want to create a rule based on a variable specific to an event. Example: The following event is implemented in your site’s source code: ``` tC.event.add_to_cart(this, {"product_name":"iphone", "product_id":"1234"}) ``` To call a tag only if the product name is “iphone”, you have to select the event variable named “product\_name” and configure it in the following manner: ![](https://2673302412-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LdtBYhZj-wxWhoZaUXI%2F-LqHAJgxXBingSa2W27v%2F-LqHAcnXVERqUsRkpIF0%2Fevent_rule%5B1%5D.png?alt=media\&token=59f15734-0772-49ba-ab7e-3bd01cb2c9e7) ## Cookie The “**Cookie**” tab allows you to create rules based on cookies you have previously created in the Commanders Act interface or which are available for your site’s domain name (first-party cookies). **Condition and behavior** “**If Cookie Equals**“: Tag activated if the cookie’s value equals the specified value. “**If Cookie Is Not Equal**“: Tag activated if the cookie’s value differs from the specified value. “**If Cookie Contains**“: Tag activated if the cookie’s value contains the specified value. “**If Cookie Doesn’t Contain**“: Tag activated if the cookie’s value does not contain the specified value. Example: In order to call a tag when your “user\_logged” cookie equals “1”, you must select the “If Cookie Equals” rule and configure it in the following manner: ![](https://2673302412-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LdtBYhZj-wxWhoZaUXI%2F-LqHAgUlviKXMBz2KAgt%2F-LqHAnPUqUSh_qRhJYzF%2Fcookie_rule%5B1%5D.png?alt=media\&token=bb57a03b-550a-4271-a694-6bcd6e51f54d) ## URL This tab allows you to create rules based on your site’s URLs (note: we **recommend** that you use rules based on variables instead of URLs since the rule will become obsolete if your URL changes in the future): **Condition and behavior** “**If URL Equals**“: Tag activated if the URL equals the specified value. “**If URL Contains**“: Tag activated if the URL contains the specified value. “**If URL Doesn’t Contain**“: Tag activated if the URL does not contain the specified value. “**If URL Matches**“: Tag activated if the URL matches the specified value (regular expressions allowed: \* to match any character and ^ for “variable begins with”). “**If URL Doesn’t Match**“: Tag activated if the URL does not match the specified value (regular expressions allowed: \* to match any character and ^ for “variable begins with”). Example: to call a tag when your URL indicates that the user is on the product page (providing your product page URLs are all structured the same: ), you have to select the “If URL Matches” rule and configure it in the following manner: ![](https://2673302412-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LdtBYhZj-wxWhoZaUXI%2F-LqHAt3DyrXRRLp9PIi0%2F-LqHAycbHQ7T0JYIX3pA%2Furl_rule-1%5B1%5D.png?alt=media\&token=b81378c8-2216-43b7-9bc9-645443a77614) ## **Browser** This tab allows you to create rules based on browsers. **Condition and behavior** “**If Browser Is**“: Tag activated if the browser is (choose from the list). “**If Browser Is Not**“: Tag activated if the browser is not (choose from the list). ![](https://2673302412-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LdtBYhZj-wxWhoZaUXI%2F-LqHAt3DyrXRRLp9PIi0%2F-LqHB9DepblWNifKE1RQ%2Fbrowser_rule-1%5B1%5D.png?alt=media\&token=1a9df58e-404b-4221-ba42-aab78e37ed34) ## Mobile This tab allows you to create rules based on the type of device. **Condition and behavior** “**If Device / OS Is**“: Tag activated if the device is (choose from the list). “**If Device / OS Is Not**“: Tag activated if the device is not (choose from the list). “**If Device / OS Is Android Tablet**“: Tag activated if the device is an Android tablet. “**If Device / OS Is Android Mobile**“: Tag activated if the device is an Android mobile device. “**If Device / OS Is Not Android Tablet**“: Tag activated if the device is not an Android tablet. “**If Device / OS Is Not Android Mobile**“: Tag activated if the device is not an Android mobile device. Example: to prevent a tag from being called on an Android mobile device, you must select the “If Device Is Not Android Mobile” rule and configure it in the following manner: ![](https://2673302412-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LdtBYhZj-wxWhoZaUXI%2F-LqHAt3DyrXRRLp9PIi0%2F-LqHBM8iBsZi02tBcPxG%2Fmobile_rule%5B1%5D.png?alt=media\&token=25acea8c-cd98-46c2-9abd-0bff006202c6) ## DataCommander This tab allows you to create rules based on the type of audience segments created in DataCommander. **Condition and behavior** “**DataCommander OR condition (up to six variables)**“: Tag activated if at least one of the audiences equals the specified value. “**DataCommander AND condition (up to six variables)**“: Tag activated if all the audiences equal all the specified values. “**DataCommander Event activation**“: Tag activated on an event ![](https://2673302412-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LdtBYhZj-wxWhoZaUXI%2F-LqHAt3DyrXRRLp9PIi0%2F-LqHBUL8T24wJlkq7RrB%2Fdata_rule%5B1%5D.png?alt=media\&token=1a7d9138-e596-4165-b65b-cb23f9e0d5e4) ## Advanced rules This tab allows you to create all types of advanced rules. For example, you can create sampling rules or even “**Custom**” rules: **Condition and behaviour** “**Sampling (1/X) (Page Based)**“: Tag activated in X% of page views. “**Sampling (1/X) (Session Based)**” : Tag activated in X% of visits. “**Sampling (1/X) (Visitor Based)**“: Tag activated for X% of visitors. “**(A or B or C or D or E) AND (F or G or H or I or J)**“: Tag activated if at least one of the variables in the first group AND at least one of the variables in the second group equal the specified values. “**(A and B and C and D and E) AND (F or G or H or I or J)**“: Tag activated if all the variables in the first group AND at least one of the variables in the second group equal the specified values. “(**A and B and C and D and E) OR (F and G and H and I and J)**“: Tag activated if all the variables in the first group OR all the variables in the second group equal the specified values. “**(A and B and C and D and E) OR (F or G or H or I or J)**“: Tag activated if all the variables in the first group OR at least one of the variables in the second group equal the specified values. “**(A different than VALUE1) OR (B different than VALUE2)**“: Tag activated if the first variable is not equal to a value OR the second variable is not equal to a value. “**(A different than VALUE1) OR (B equals VALUE2)**“: Tag activated if the first variable is not equal to a value OR the second variable is equal to a value. “**(A different than VALUE1) AND (B different than VALUE2)**“: Tag activated if the first variable is not equal to a value AND the second variable is not equal to a value. “**(A different than VALUE1) AND (B equals VALUE2)**“: Tag activated if the first variable is not equal to a value AND the second variable equals a value. “**In Array**“: Tag activated if the variable is present in the variable array. “**In Sub Array**“: Tag activated if the variable is present in a variable array key. “**Array Intersectio**n”: Tag activated if two variables from two variable arrays are equal. “**Custom**“: Custom rule (to define in JavaScript). Example: In order to call a tag for 25% of site visitors, you must select the “Sampling (1/X) (Visitor Based)” and configure it in the following manner: ![](https://2673302412-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LdtBYhZj-wxWhoZaUXI%2F-LqHAt3DyrXRRLp9PIi0%2F-LqHBcjitg-bAJEDKFDP%2Fsample_rule%5B1%5D.png?alt=media\&token=cbc6aeae-0938-43a7-9624-aeeb62913b5b)
