What are Cookies?
Cookies are text files containing small amounts of information which are downloaded to your device when you visit a website. Cookies are then sent back to the originating website on each subsequent visit, or to another website that recognises that cookie. Cookies are useful because they allow a website to recognise a user’s device. You can find more information about cookies by visiting:
There are several types of cookies that are used to keep track of information needed by a site user as they travel from page to page within a website.
Cookies on IoD Sites and Microsites
Cookies can be used to track internet activity after the user has left a website. These are normally facilitated by organisations external to the website being visited and are generally known as ‘third-party’ cookies. They usually have a long lifetime with several months being quite common. They are 'harvested' and 'refreshed' whenever the user visits a page where the same or a similar cookie is being used.
The ASP.NET_SessionId cookie is related to the Member login cookie. It is used by ASP.NET to create a session cookie that contains 'session id' and is required for everyone visiting the site. This helps to maintain security and to keep track of visitor data. It is a required cookie for forms where it allows the data entered to be processed.
Third-party cookies and microsites
The domain specified in the cookie relates to the cookie's owner (the "party"), who has set the cookie. iod.com cookies will have the iod.com domain specified in a cookie. These are first-party cookies.
iod.com sets a number of cookies. These are used to analyse visitors' browsing of iod.com for future improvements and to provide certain useful functions such as storing your login details, if you are an IoD member. The data is not used to identify individual members.
A third-party cookie is set when you visit a site but the domain named in the cookie sent to your computer is not the same as the website. For example, if you visit iod.com, you may visit the
Other Third Party processing activities
If you shorten our site URLs, for example on Twitter or Facebook, we may use services such as goo.gl, bit.ly, tinyurl.com and ow.ly to do so, and our site works with these to rebrand our URLs as a https://www.iod.com/xxxxx link. Also our website sometimes offers features that allow users to share links with social networks and our site may shorten that URL using one of these services.
These services provide us with anonymised, aggregated statistics relating to the use of our shortened URL, for example by telling us how many times it has been clicked on. We do not have access to the IP address of your computer collected by these services or any other identifiable information about you. Nor do they have any access to data collected on our website.
For more information on these services please see below:
We currently use Google Analytics to measure and analyse visitor information related to our web site. For that purpose, your IP address, internet traffic data and data on your browser type and PC are collected using several cookies (_utma, _utmc, utmb, utmz):
- _utma is used by Google Analytics to identify first-time site ('unique') visitors vs. returning visitors. It expires after two years
- _utmz tracks source visits (the origin of the visit). It expires after six months.
§_utmc identifies unique visitors vs. returning visitors but expires when you close your browser.
§_utmb is used for general visitor tracking and expires after 30 minutes.
Google may also transfer this information to third parties where required to do so by law, or where such third parties process the information on Google’s behalf. Google will not associate your IP address with any other data held by Google. For information on how to reject or delete this cookie.

Microsites are collections of webpages created as a discrete entity within a larger website. Microsite pages are usually related by content on a similar topic. They often have a different domain name from the parent website and content for microsites may be provided by specialist organisations.
iod.com hosts several microsites on our servers and links to many others hosted by our corporate partners. The IoD does not control dissemination of third party cookies.
The .ASPXAUTH (Member login) cookie holds login information regarding the current session from a user on the site. It is used for quick reference and is encrypted by .net to ensure security.
The EventBooking cookie holds information required to book an event. It includes information such as booker name, guest name, job and company as well as the event ID and any special requirements of the booker and guests entered. This is necessary to enable the booking process to be completed and passed over to the shopping basket. A cookie is created for each event being booked.
The EventBasket cookie enables the visitor to complete a transaction and pay for an event they have selected in the booking process. It contains event IDs that have been added to the basket.
iFrames are set up on some of our pages to present event and booking information. IRIS provides iFrames for this purpose and may present cookies.
Cookies Set By Third Party Sites
We sometimes need to embed media content from third party websites. For example photos from flickr and video content from websites such as YouTube and Twitter. As a result, when you visit a page with content from sites like these, you may be presented with cookies from these websites. We do not control these so you should check the relevant third party website for more information.
If you share information on this site with friends through social networks e.g. Facebook or Twitter you may be sent cookies from these websites. We do not control these cookies so please check the relevant third party website for more information.
Internet browsers normally accept cookies by default, but it is possible to set a browser to reject cookies. If this is done it is important not to exclude the benign and useful cookies. Choose an option that rejects all third party and long-lived cookies.
