-  * Response header's value - To use a captured response header value from the preceding Condition, specify the syntax as `{http_resp_headerName}`. You can use `{capt_header_value_matcher}` when the value is captured from Action Set's "Set-Cookie" response header. Know more about [capture under Action set](#syntax-for-capturing).

This optional field lets you match as well as capture the value of a specific header when multiple Set-Cookie headers with the same name exist. To manipulate that specific cookie's captured value, you can then use `{capt_header_value_matcher}`. Know more about [capture under Action set](#syntax-for-capturing).
   * Server variable - To use a server variable, specify the syntax as `{var_serverVariable}`. [List of supported Server variables](#server-variables).
