Property Manager lets you create your own variables to better control how our network serves your traffic. Using variables, you can fine-tune your properties and reduce dependency on your support representatives.

Characteristics of user-defined variables:

They start with a PMUSER_ prefix.
With the Set Variable behavior, they can be populated with fixed strings, values from other variables, randomly generated values, and extracted values from the incoming request (cookies, headers, URL path/extension, query strings, etc). See Set Variable behavior for details.
With the Set Variable behavior, they can be transformed using a number of different operations, such as extracting substrings, upper/lower case, search/replace, encode/decode, etc.

Security settings

Unlike built-in variables that have a default, non-editable hidden security setting, user-defined variables let you choose the security level when you create the variable.

Visible

Variables are returned to the client in the X-Akamai-Session-Infoheader in response to the Pragma: akamai-x-get-extracted-valuesrequest header.

Hidden

Hidden variables are not returned to the client in the X-Akamai-Session-Infoheader in response to the Pragma: akamai-x-get-extracted-valuesrequest header.

📘
If your variables contain information you don't want to expose on the Internet, set the variable attribute to Hidden.

Sensitive

As with hidden variables, sensitive variables are not returned via the Akamai pragma debug headers. In addition, sensitive variables:

Can't be sent to end-users through Set-Cookie or Response Header Property Manager behaviors.
Can't be added to the custom logging field.
Propagate their sensitive attribute to any new variable created from a sensitive variable, meaning that the new variable also has a security setting of Sensitive.

📘
If your variables contain personal information (PII) or any other really sensitive data, set the variable attribute to Sensitive.

Create a variable

In order to match on or modify a variable, you must create the variable.

From the Property Manager editor:

In the Property Variables section of the Property Manager editor, click Add Variable.
Create a name for the variable. Do not add the PMUSER_ prefix for the variable. It is automatically included on your behalf.
Optionally enter an Initial Value for the variable.
Enter a meaningful description for your variable.
Select Security settings.

What you should see

The variable is ready for use. You do not have to save the property to use the variable, but we suggest you save often as a best practice.
