I want to have hyperlink on my VF page and this page has to be shown on customer portal. The hyperlink will imitate logout functionality. I used following url "/secur/logout.jsp" but it is not working. Am I missing anything here?
This should work:
Its what salesforce generates when you set up a force.com site.
Use href="/secur/logout.jsp" in anchor tag
and if u want to do in ccontroller use
Hope this will work for u:-)
