This page provides more information about what cookies are exactly, which cookies are used by and how you can affect cookies.

What are cookies?

A cookie is a small piece of text issued to a visiting browser by a web server in the hope and expectation that the browser will return this upon a subsequent visit to the site.
The cookie is a supplement to the HTTP specification. HyperText Transfer Protocol is used by everyone who visits a website: it handles the communication between the web server and the browser. However, it is not designed to view successive page visits as a single entirety. Therefore, it is not always possible to retrieve information or settings during a subsequent visit.
In order to enable this nonetheless, cookies and set-cookie-headers for HTTP were introduced in 1997. This specification was updated most recently in April 2011 and is currently called the RFC 6265 HTTP State Management Mechanism.


How do cookies work?

In contrast to what politicians sometimes claim, cookies are themselves not programs and they are also not files. Furthermore, technically speaking, nothing is stored by the web server on the visitor's computer. That is something the browser can decide completely independently for itself. Ultimately, cookies are often saved as a file, but a web server cannot force the browser actually to store cookies or to return them upon a subsequent visit.
A cookie is always linked to a specific domain or subdomain. Examples of domains and subdomains, respectively, are "" and "
So cookies are always returned to the same domain as the one from which they come. You can only know for certain that the servers receive cookies that had been gotten previously via Access to the cookies that were placed by can only be gotten via JavaScript on
An important thing about cookies is that they are received with every HTTP request and that all known and relevant cookies are set along with this for each request. This also applies to the requests for images, JavaScript and css files for a webpage. Naturally, domain control is then also applied.

First-party cookies

Cookies that you get for the same domain that you're visiting are called first-party cookies. So, when looking at this page, the cookies from are first-party cookies.

Third-party cookies

A website may also contain elements from third parties. Familiar examples include embedded videos, advertisements and social media buttons. If cookies are sent along with these elements from their own servers, these are called third-party cookies. So it is then possible that when visiting, you get third-party cookies from, and other third-party websites.
Due to the way HTTP works and to security concerning cookies, it is not possible for the particular first party - i.e., in our case - to influence whether third-party cookies are set along.

What other storage is there for websites?

Since 1997, in addition to cookies, increasing possibilities for browser storage have arisen. Since hardly makes use of these, they are mentioned here only briefly.
Flash applications have their own type of cookies comparable to those for HTTP. Except for user preferences in the video player, cheapCAD does nothing with this type of cookies.
Html5 local storage is a recent development. In comparison with cookies, web applications can use this to store large quantities of data. Due to the limited support in browsers, cheapCAD makes only limited use of this.


What are cookies used for on

Cookies make it possible to retrieve information from previous visits. In practice, this is used to record the fact that you logged in, that you configured certain settings and that you have previously viewed certain site elements. Cookies that adjust the functioning of the site to your desires are called functional cookies.
Furthermore, cookies can also be used to tell the site that a visitor has visited previously. Such information allows the collection of statistics about the use of the website. One familiar example is Google Analytics. This uses only anonymised statistical information that we then use to analyse and to improve the working of the site.
Information about your visiting behaviour can also be used to align advertisements to your interests. For this, only uses anonymised information about pages that you have visited previously at
User profiles drawn up using cookies are never shared with third parties and are used only to improve the quality and relevance of
