[Zope] show all http headers

[Mark McEahern]

What's the equivalent in Zope to the following VBScript/ASP snippet:

  For Each x in Request.ServerVariables
    Response.Write "<p>" & x & " = " & Request.ServerVariables(x)
  Next

For what it's worth, my reason for asking--aside from general debugging
knowledge--is because I want to see whether my:

  squid --> apache --> zope

setup is passing along an X-Forwarded-For http header.  For now, Apache is
recording the internal IP address of the squid proxy in the weblogs, which
is pretty useless.
