Hi, Here is my first lines of the standard_html_header : <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <HTML><HEAD><META HTTP-EQUIV="Content-Type" CONTENT="text/html;"> Here is the first lines received from the server by my browser : <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <HTML><HEAD> <base href="http://www.frenchradiology.net/cerf/" /> <META HTTP-EQUIV="Content-Type" CONTENT="text/html;"> As you can see my Zope's server added the base href ? How can I do to not have this href, or modify if necessary ? Sincerily PS -------------------------------------------------- Oreka ! Nous sommes l'internet moins cher !
