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.
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.
|Cookie name||Notes on uses|
A single log-on works across most IET sites. These authorisation ("log-on") cookies simply contain session IDs, identifying you as an individual logged-on user. This avoids the need to send your user name and password every time that you request a page; therefore, the aim is enhanced security.
No personal information is stored in these cookies. If you choose not to use "Remember Me", the cookies are deleted when you log off from the IET sites, or close your browser. Please ensure that you accept all of these cookies if you wish to register and/or log on to the sites.
The book shop also uses your existing site cookies to keep track of the contents of your shopping basket, rather than setting additional ones. Without accepting cookies, you will not be able to use the shop.
|In the discussion forums, there are further log-on cookies. The forums set other cookies, one for the last date you visited, and one for the latest posts you have seen. The aim is to be able to offer you quick access to the new postings when you next visit. These are permanent cookies. You can delete these additional cookies if you wish - it will just mean that the site cannot indicate new messages to you.|
Determines the behaviour (shown or hidden) of the black (previously green) bar at the top of most IET web pages.
The E&T Jobs site also uses supplementary cookies. Rejecting these cookies will mean that you are not recognised as logged on when visiting this site, even though log-ons work normally on other IET sites.
|These are supplementary log-on cookies for MyCommunity, similar to those above for E&T Jobs.|
A second cookie records your preferred language for Archives searches.

Site advertising servers are provided by Real Media Open Adstream [new window]. Advertising mainly appears in specific sites, such as E&T Magazine and IET Electrical. Cookies are used, for example, to avoid showing you the same advertisement twice on different pages. They are delivered from a server in theiet.org, so (as described above) they cannot be used to correlate your behaviour with your visits to non-IET sites.
Your use of the IET site will not be affected should you decide not to accept these "oax" advertising cookies.
The IET uses Google Analytics. This service uses theiet.org cookies [new window] to record and process information about your use of the sites (including your IP address) on behalf of the IET. The IET uses this information to evaluate visitors’ use of the sites and to compile statistical reports on site activity; the reports examine patterns of use rather than the behaviour of individual users.
You can opt out of Google Analytics [new window] tracking for all sites, including the IET ones.

The IET also uses Scout Analytics [new window] on some of its sites, to understand better its users' subject interests and behaviour. The resulting profiling assists the IET in offering more relevant content and services to its members and other visitors. Scout Analytics uses both first- and third-party cookies. You may block these without affecting your use of the site.
The cookies come both from theiet.org and from scout.scoutanalytics.net
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 site AllAboutCookies [new window] provides independent information on cookies, and how to block them in specific browsers.
