For example, a web site may allow you to customize the content and layout of the pages you see, so that your choices are persistent across different visits to that web site.</p><p>The web site is able to remember your preferences by storing a cookie on your computer. Then, on future visits, the web site retrieves the information stored in the cookie to format the content of the site according to your previously specified preferences.</p><p>Thus, cookies play a very useful role in web browsing. Unfortunately, web sites often store and retrieve information in cookies without your explicit knowledge or consent. Some of this information may be quite useful to the web site owners, for example, by allowing them to collect summary statistics on the number of visits different areas of the web sites get, or to customize banner advertising.</p><p>The cookies page allows you to set policies for the use of cookies when you are browsing the web with the <span class="application">Konqueror</span> web browser.</p><div class="warning" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Warning</h3><p>Note that the policies that you set using this control module will <span class="emphasis"><em>not</em></span> apply to other web browsers such as <span class="application">Firefox</span>.</p></div><div class="sect2"><div class="titlepage"><div><div><h3 class="title"><a name="cookie-policy"></a>Policy</h3></div></div></div><p>Using the <span xmlns:doc="http://nwalsh.com/xsl/documentation/1.0" class="guiitem"><span class="guilabel">Policy</span></span> tab, you can configure the <span class="orgname">KDE</span> applications that will handle cookies. You can do this by specifying a general cookie policy as well as special cookie policies for certain domains or hosts.</p><p>The top of the policy tab has a check box labeled <span xmlns:doc="http://nwalsh.com/xsl/documentation/1.0" class="guiitem"><span class="guilabel">Enable cookies</span></span>. If you leave this unchecked, cookies will be completely disabled. However, this may make browsing rather inconvenient, especially as some web sites require the use of browsers with cookies enabled.</p><p>You will probably want to enable cookies and then set specific policies on how you want them to be handled.</p><p>The first group of options create settings that apply to all cookies.</p><div class="variablelist"><dl class="variablelist"><dt><span class="term"><span xmlns:doc="http://nwalsh.com/xsl/documentation/1.0" class="guiitem"><span class="guilabel">Only accept cookies from originating server</span></span></span></dt><dd><p>Some pages try to set cookies from servers other than the one you are seeing the <acronym class="acronym">HTML</acronym> page from. For example, they show you advertisements, and the advertisements are from another computer, often one that belongs to a large advertising group. These advertisements may try to set a cookie which would allow them to track the pages you view across multiple web sites.</p><p>Enabling this option will mean only cookies that come from the same web server as you are explicitly connecting to will be accepted.</p></dd><dt><span class="term"><span xmlns:doc="http://nwalsh.com/xsl/documentation/1.0" class="guiitem"><span class="guilabel">Automatically accept session cookies</span></span></span></dt><dd><p>An increasingly common use for cookies is not to track your movements across many visits to a web site, but to just follow what you do during one single visit. Session cookies are saved as long as you are looking at the site, and deleted when you leave it.</p><p>Web sites can use this information for various things, most commonly it is a convenience so that you do not have to keep logging in to view pages. For example, on a webmail site, without some kind of session <acronym class="acronym">ID</acronym>, you would have to give your password again for each email you want to read. There are other ways to achieve this, but cookies are simple and very common.</p><p>Enabling this option means that session cookies are always accepted, even if you don't accept any other kind, and even if you choose to reject cookies from a particular site, session cookies from that site will be accepted.</p></dd></dl></div><p>The section for <span xmlns:doc="http://nwalsh.com/xsl/documentation/1.0" class="guiitem"><span class="guilabel">Default Policy</span></span> sets some further options that are mutually exclusive — you can choose only one of these options as the default, but you are free to set a different option for any specific web server.</p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p>Site specific policies always take precedence over the default policy.</p></div><div class="variablelist"><dl class="variablelist"><dt><span class="term"><span xmlns:doc="http://nwalsh.com/xsl/documentation/1.0" class="guiitem"><span class="guilabel">Accept all cookies</span></span></span></dt><dd><p>If this option is selected, all cookies will be accepted without asking for confirmation.</p></dd><dt><span class="term"><span xmlns:doc="http://nwalsh.com/xsl/documentation/1.0" class="guiitem"><span class="guilabel">Accept until end of session</span></span></span></dt><dd><p>Cookies will be accepted, but they will expire at the end of the session.</p></dd><dt><span class="term"><span xmlns:doc="http://nwalsh.com/xsl/documentation/1.0" class="guiitem"><span class="guilabel">Ask for confirmation</span></span></span></dt><dd><p>If this option is selected, you will be asked for confirmation every time a cookie is stored or retrieved.

In this dialog, you can type the name of the domain (with a leading dot), then select the policy you want to apply to this domain.
