# Client-Side Tags (C2S - Client to Server)

**Those tags will execute on the front end of the client's (website visitor's browser) device**, impacting the website performance and possibly introducing third-party libraries (JS files) to their sources on the website. Additionally, all data communication (beacons and other signals) will use HTTP POST or GET to the third party, exposing the client's IP address and other HTTP header fields to the third party's receiver (server).

Some restrictions apply to the availability of components when tags for the client side are configured. For example, you can not use server-side variable values for those configurations, and the transformation functions (such as anonymization or pseudonymization) are not available.
