## General Information

The web.addCookie function adds, deletes, or edits a cookie. If the name and path match an existing cookie:

- If the `expires` date has past, the cookie is deleted.
- Else, the existing cookie is overwritten.

You can use web.addCookie prior to starting the run to add cookies usually stored in the browser. You can also add a cookie in any case where the automatic handling of cookies is not appropriate for your test.

In a web.addCookie call, the `domain` attribute is required, though it is generally optional. In normal browsing, if the domain is not specified in a Set–Cookie header, the value of domain is the host name of the server that generated the cookie response. Since this information is not available to the load generator host, `domain` is required.

Note: Scripts do not read or modify the cookies that are stored by your browser. Instead, each script uses the cookies that are sent to the Vuser by the server host at runtime. These cookies are maintained only temporarily while the script runs. The web–cookie functions (web.addCookie, web.removeCookie, and web.cleanupCookies) manipulate only these temporary cookies.

## Example

    web.addCookie("client_id=China127B; path=/; expires=Wednesday,09-Nov-2001 23:12:40 GMT; domain=www.mycompany.com")

    web.addCookie(
      {
        name:"client_id",
        value: "China127B",
        path: "/",
        expires :"Wednesday,09-Nov-2001 23:12:40 GMT",
        domain : "www.mycompany.com"
      }
    );
