<para>Cookies are a mechanism used by web sites to store and retrieve
|
|
information using your browser. 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.</para>
|
|
|
|
<para>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.</para>
|
|
|
|
<para>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.</para>
|
|
|
|
<para>The cookies module of the &kcontrol; allows you to set policies
|
|
for the use of cookies when you are browsing the web with the
|
|
&konqueror; web browser. </para>
|
|
|
|
<warning><para>Note that the policies that you set using this control
|
|
module will <emphasis>not</emphasis> apply to other web browsers such
|
|
as &Netscape;.</para></warning>

<para>Using the <guilabel>Policy</guilabel> tab, you can configure the
|
|
&kde; 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.</para>
|
|
|
|
<para>The top of the policy tab has a checkbox labeled <guilabel>Enable
|
|
cookies</guilabel>. 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.</para>
|
|
|
|
<para>You will probably want to enable cookies and then set
|
|
specific policies on how you want them to be handled.</para>

|

<para>The first group of options create settings that apply to all cookies.</para>

<listitem>
|
|
<para>Some pages try to set cookies from servers other than the one
|
|
you are seeing the <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.</para>
|
|
<para>Enabling this option will mean only cookies that come from the
|
|
same web server as you are explicitly connecting to will be
|
|
accepted.</para>

<term><guilabel>Automatically accept session cookies</guilabel></term>
|

<listitem>
|
|
|
|
<para>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.</para>
|
|
|
|
<para>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>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.</para>
|
|
|
|
<para>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.</para>

cookies. That is, they are not kept when you leave the

web site.</para>

<note>
|

<para>The definition of <quote>leave the web site</quote> is vague.

Some cookies may hang around for a little while after you are no

longer viewing any pages on a particular web site. This is

normal.</para>

policies for specific host domains using the controls in the <guilabel>Domain

<para>The Ask, Accept, or Reject policy can be applied to a specific

brings up a dialog. 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. Note that entries may also get added while you are
|
|
browsing, if the default policy is to ask for confirmation, and you
|
|
choose a general policy for a specific host (for example, by selecting
|
|
<guilabel>Reject all cookies from this domain</guilabel> when asked to
|
|
confirm a cookie).</para>

<para>You can also select a specific host domain from the list and click the

<guibutton>Change</guibutton> button to choose a different policy for that

domain than the one shown in the list.</para>

<para>To delete a domain specific policy, choose a domain from the list, and

apply to domains which have been deleted from the list.</para>
