Is there a way to use the cookie-selector to check if a cookie
exist, whatever value it has.
No there isn't. The CookieSelector class returns false when a cookie
does not exist, i.e. map:otherwise will be executed. You would need
to know all possible values of the cookie to be sure that
map:otherwise means cookieDoesNotExist. An example:
<map:select type="cookie-selector">
<map:parameter name="cookie-name" value="myCookieID"/>
<map:when test="">
<map:generate src="cookieIsEmpty.xml"/>
</map:when>
<map:when test="value1">
<map:generate src="cookieEqualsValue1.xml"/>
</map:when>
<map:when test="value2">
<map:generate src="cookieEqualsValue2.xml"/>
</map:when>
...
<map:otherwise>
<map:generate src="cookieDoesNotExist.xml"/>
</map:otherwise>
</map:select>
To test for cookieDoesNotExist or cookieIsEmpty you can use the
cookie input module:
<map:select type="parameter">
<map:parameter name="parameter-selector-test"
value="{cookie:myCookieID}"/>
<map:when test="">
<map:generate src="cookieIsEmptyOrDoesNotExist.xml"/>
</map:when>
<map:otherwise>
<map:generate src="cookieHasValue.xml"/>
</map:otherwise>
</map:select>
When your application is fine with the same behavior for an empty
cookie as for a non-existing cookie you can go with this solution.
I think that for testing cookieDoesNotExist without cookieIsEmpty a
new selector or input module is necessary.

I tried :
<map:select type="cookie-selector">
<map:parameter name="cookie-name" value="myCookieID"/>
<map:when test="">
<map:generate src="nothing.xml"/>
</map:when>
<map:otherwise>
<map:generate type="wsproxy" src="{global:ws-url}Id=
{request:cookieMap/myCookieID/value}"/>
</map:otherwise>
</map:select>
but it works if the cookie exist and has an empty value, not if the
cookie does not exist.
