Why are cookies used on the IET websites?
Often, websites need to maintain information as you move from page to page, and possibly between your browsing sessions. For example, you expect, when moving between pages in a web shop, that the site will keep track of the contents of your shopping basket. If you have logged in, you expect the site to recognise you on each subsequent page. Cookies are used to meet these expectations.
Cookies are small pieces of identifying information, stored by your browser on your PC, to enable such information about your session to be maintained. The cookie may contain actual information (e.g. the date of your last visit), or just a unique reference ID that allows the site to look up (for example) the contents of your shopping basket in its databases.
Cookies set by one site cannot be read by another. However, one web page may be made up of components (such as news stories, images or advertising), some of which are delivered from third parties. Each of those third-party sites will be able to set and read its own cookies on any page where its content appears.
How are cookies used on the IET websites?
The short version
If you block cookies from the IET websites, you will not be able to log in, and a range of other functions, such as the shopping basket and the tracking of new messages in the discussion forums, will fail. However, you will be able to browse most of the information on the IET sites. The IET uses some third-party services, and you may need to consult their policies separately.

Notes on uses
Cookies with suffix _session
Description: used by the Zapnito platform to identify who you are. Assigned when you log in, this keeps you logged in to the site so you don’t have to constantly re-enter your username and password. This isn’t set unless you are a registered user. Expiration: when the browsing session ends.
Description: Google Analytics cookie, not used in ga.js. Set for interoperability with urchin.js. Historically, this cookie operated in conjunction with the __utmb cookie to determine whether the user was in a new session/visit. Expiration: End of browser session.
Cookies with gs_u_GSN prefix
Description: HTML5 local storage used by the Zapnito platform to store local data to improve performance of the website to improve the experience of using the site.
In addition, the IET uses third parties to deliver services to members and others. These third-party servers may set cookies in accordance with their own cookie and privacy policies, which you should consult separately. They include:
- The IET uses email services from Adestra to inform its members and contacts of relevant activities, events, services and products. The levels of response to these emails are tracked, in order to improve the effectiveness of IET communications. Since emails are sent from addresses in the domain email.ietinfo.org, and should you click on links in such emails, you may find cookies from that domain.
- IET.tv, which uses Stream UK to deliver webcasts. These appear mostly in the IET.tv site, but also embedded in some web pages elsewhere. You may block cookies from scpro.streamuk.com if you wish.
- The electronic information services provided to members by the IET Library.
- Some pages, especially in E&T Magazine, include content from Twitter, YouTube, Flickr and other services. These have their own cookie and privacy policies.
- If the IET is currently conducting a survey or requesting feedback (for example in user trials), cookies may be used to record the fact that you have seen the invitation to respond. The aim is to avoid showing you the invitation repeatedly. If you reject these cookies, you may see the message a number of times.
