I'd like to provide a link, whereby clicking it would generate a login prom=
pt
and then return to the calling page.

I thought I'd just create a script, viewable by only the people in the role
that I want to login.

I did this, and tried just to use,

context.REQUEST.RESPONSE.redirect(context.REQUEST['HTTP_REFERER'])

This doesn't work. Or I should say, it half works. If the login is successf=
ul,
the page is returned but the user object hasn't been updated (has_roles()
doesn't work) and subsiquent clicks of the link don't prompt for
authentication.

Can anyone tell me why this isn't doing what I want it to, or how to create=
 a
simple "click here to login" script?

Cheers,
