What is a Cookie?

A cookie is a small text file of letters and numbers that is used to distinguish you from another user and enables swift passage from one page to the next on our website.

Why do we use Cookies?

Cookies help us to provide you with a better customer experience when you browse to our website and allow us to improve and tailor the site for you. For example, we keep track of the domains from which people visit and we also measure visitor activity on the site, but we do so in ways that keep the information anonymous. We use the information that we collect to measure the number of visitors to the different areas of our website, and to help us make the site more useful to you.

Cookie Types

Our website uses three types of cookies. They are as follows:

System Cookies

These enable us to keep track of your movement from one page to another so that you do not get asked for the same information twice. Our shopping basket uses system cookies to remember your selections so that when you proceed to the checkout we know what you have selected rather than your shopping basket being empty.

Cookie Types

WebSphere Commerce supports two types of session management: cookie-based and URL rewriting. For a full explanation of what each mean please make reference to the following link Session Management

WebSphere Commerce contains the following session cookies:

Cookie Name Cookie Description
WC_SESSION_ESTABLISHED This cookie is created on the first request processed by WebSphere Commerce runtime. For example, a non-cache request. See Dynamic caching considerations for persistent session for more information.
WC_ACTIVEPOINTER This cookie contains the value of the store ID of the session. This value is used to select the store to execute the command, if one is not specified on the URL.

For example: WC_USERACTIVITY_-1000

This is a user session cookie that flows between the browser and server over both SSL or non-SSL connection. It is used for user identification over non-SSL connections. It contains user session values such as login timeout, session identifier, etc.
WC_GENERIC_ACTIVITYDATA This cookie only exists if it is a generic user (-1002) session. This cookie stores the session values such as storeid, langid, contracts, etc.

For example: WC_AUTHENTICATION_-1000

WebSphere Commerce uses a secure authentication cookie to manage authentication data. An authentication cookie flows only over SSL, and has a time stamped signature for increased security. This cookie is used to authenticate the user over SSL-connections.

Analytic Cookies

These enable us to recognize and count the number of visitors to the website, and to see how you navigate the site. These cookies help us to improve the way our website works, for example by making sure that users can find what they want quickly and easily.

Google Analytics

Cookie Types

Reference to

Google Analytics sets the following cookies as described in the table below. A default configuration and use of Google Analytics sets only the first 4 cookies in the table.

Name Description Expire
__utma This cookie is typically written to the browser upon the first visit to your site from that web browser. If the cookie has been deleted by the browser operator, and the browser subsequently visits your site, a new __utma cookie is written with a different unique ID. This cookie is used to determine unique visitors to your site and it is updated with each page view. Additionally, this cookie is provided with a unique ID that Google Analytics uses to ensure both the validity and accessibility of the cookie as an extra security measure. 2 years from set/update.
__utmb This cookie is used to establish and continue a user session with your site. When a user views a page on your site, the Google Analytics code attempts to update this cookie. If it does not find the cookie, a new one is written and a new session is established. Each time a user visits a different page on your site, this cookie is updated to expire in 30 minutes, thus continuing a single session for as long as user activity continues within 30-minute intervals. This cookie expires when a user pauses on a page on your site for longer than 30 minutes. You can modify the default length of a user session with the _setSessionCookieTimeout() method. 30 minutes from set/update.

This cookie is no longer used by the ga.js tracking code to determine session status.

Historically, this cookie operated in conjunction with the __utmb cookie to determine whether or not to establish a new session for the user. For backwards compatibility purposes with sites still using the urchin.js tracking code, this cookie will continue to be written and will expire when the user exits the browser. However, if you are debugging your site tracking and you use the ga.js tracking code, you should not interpret the existence of this cookie in relation to a new or expired session.

Not set.


This cookie stores the type of referral used by the visitor to reach your site, whether via a direct method, a referring link, a website search, or a campaign such as an ad or an email link. It is used to calculate search engine traffic, ad campaigns and page navigation within your own site. The cookie is updated with each page view to your site.

6 months from set/update.


This cookie is not normally present in a default configuration of the tracking code. The __utmv cookie passes the information provided via the _setVar() method, which you use to create a custom user segment. This string is then passed to the Analytics servers in the GIF request URL via the utmcc parameter. This cookie is only written if you have added the _setVar() method for the tracking code on your website page.

2 years from set/update.


This cookie is used by Website Optimizer and only set when the Website Optimizer tracking code is installed and correctly configured for your pages. When the optimizer script executes, this cookie stores the variation this visitor is assigned to for each experiment, so the visitor has a consistent experience on your site. See the Website Optimizer Help Center for more information.

2 years from set/update.


Cookie Types

Reference to two (2) documents Coremetrics Implementation Guide-1.pdf and Understanding_Coremetrics_Reports.pdf

In order to facilitate tracking of session and visitor activities, Coremetrics makes use of cookies.

Session Cookie:
The 'Session' cookie exists only for the lifetime of the current browser session. The Session cookie will exist from the point at which the first tag is received from the website until 1) the visitor closes all browser windows for the browser in question or 2) more than 30 minutes pass without receiving a data collection tag from the browser session. One or more 'sessions' may be associated with a 'visitor'.
Visitor Cookie:
The 'Visitor' cookie persists after the visitor closes all browser windows. The 'Visitor' cookie contains a cookie ID referenced by Coremetrics to identify a visitor returning to the site across multiple 'sessions'.


Cookie Types

The cookies that Maxymiser uses are known as "first party cookies" and are classified as "analytical cookies" which allow to recognize and count the number of visitors to see how visitors browse around the site. The website owners can then understand the areas that are not working well and find better ways to serve the customer.

Maxymiser never shares data or observations with anyone outside of the website owner and the data is used at an aggregated level so it does not and is never used to identify the customer. They don't work in the online advertising industry who use 'third party cookies'. They only work on web sites - so for instance they do not generate pop-up adverts or adverts (re) targeting the customer on third party websites.
