Cookie information

This site doesn't extensively use Cookies. It does however use them for a couple of things, so here is some information about what you need to know about those cookies.

Cookie Information
ASP.Net Session Cookie This site uses code to generate web pages, written using Microsoft's 'ASP.Net' technology. This uses a cookie to maintain the user 'session' so that you can interact with a page and the web server remembers the state of the different controls (e.g. drop down lists and things). This is purely for functionality of the site during your visit, and the cookie is neither stored for longer than your session, nor is any of the relevant data stored.
Google Analytics Cookie This site includes the standard Google Analytics code, which will set cookies in order to track various information about how users navigate through the site. For example, it shows how many unique visitors there are per day, how many people leave the site after a particular page, etc. It requires a cookie so that it can differentiate (for example) between a new user going to a page, and a current user going to that same page.

What this site knows about you.

Request Headers

Request headers are the information sent to the web server when you make a web request. Here are a few of them that you sent while requesting this page:

Headers Your value Info
Accept text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 The Accept request-header field specifies certain media types which are acceptable for the response. For example, if the request were an image file, it may specify that it can only display certain types.
Accept-Language Similar to Accept, but gives a set of preferred languages.
Cookie This shows any cookies that from the computer (for that domain) that have previously been set by the server.
Host www.findmylibrary.co.uk The domain name of the server (in this case it'll be this site).
User-Agent CCBot/2.0 (http://commoncrawl.org/faq/) Shows the browser/device (the 'agent') that is sending the request. This can be in quite a cryptic format but you should be able to recognise your browser in it.
DNT This stands for 'Do Not Track' so a true of false (0/1) can be sent to web servers requesting them not to do any tracking. Internet Explorer (10) has started sending this as 1 (True) by default.

IP Address

Your IP address is 54.224.184.251. This is your identifier; essentially your address on the Internet. At a very basic level the Internet is computers sending data back and forth to each other, and they have to know where things are coming from and where they should be sending back to.

In some cases quite a bit of information can be gained from an IP address, though a lot of the time this will be more to do with your Internet Service Provider rather than yourself, as they will be the ones that own your IP address.

Your IP address gives the following information about itself (not necessarily about you):

Information Type Your value
City
Country

JavaScript Information

JavaScript can also be run on the client to find out information about the user and the device they are running. For example:

Information Type Your value
Screen resolution
Operating system
Browser Name

Other cookies

Because this site is a socially responsible, community minded, non advertising, not for profit, one man operation, I can't tell you much about the other cookies you may have on your computer (e.g. what other sites you have visited).

It's worth giving a little bit of warning though. In theory, one site can't see what cookies another site may leave as the browser only sends the cookie data for the relevant domain. But what about the following scenario:

  1. You visit www.SiteA.com You browse around some products, put in all sorts of data. You assume this is only then held by Site A. Unknown to you the site also includes a link to some content from www.SiteX.com, an advertising provider. This has placed a cookie, recorded various bits and pieces about what you've been doing on the page, and stored information in its database about you.
  2. You then visit www.SiteB.com. Surprisingly, all the things you were doing on Site A are seemingly fully known to this site. It's now offering you ads based on what you were just doing (and what you're know doing). The secret is simply of course that SiteB also links to some content from SiteX, which is happily tracking everywhere you're going, showing ads based on what you do, and generally causing a bit of a nuisance.

So what can you do? For now, escaping tracking cookies is quite difficult, but it's a good idea to think about the following:

  1. Regularly clear out your browsing data and cookies. At the very least this would mean that tracking cookies don't accumulate too much data about you as a single individual.
  2. Set browser security settings and use privacy options (these vary between browsers obviously but they all offer similar things). You can of course reject cookies completely, but a lot of sites will unfortunately then not work. Consider setting cookies off by default and then setting sites manually into your Trusted Sites list.
