Hi, Put a slash in the file <zope directory>/lib/python/OFS/main.dtml, at line 9. <FORM ACTION="<!--#var URL1-->/" METHOD="POST"> ^^^ instead of <FORM ACTION="<!--#var URL1-->" METHOD="POST"> Your Rewrite Rules are correct : RewriteEngine On RewriteLog /new/usr/apache/logs/rewrite_log #RewriteLogLevel 9 RewriteCond %{HTTP:Authorization} ^(.*) RewriteRule ^/Zope/(.*) /home/httpd/cgi-bin/Zope.cgi/$1 \ [e=HTTP_CGI_AUTHORIZATION:%1,t=application/x-httpd-cgi,l] If you use ^/Zope(.*) /home/httpd/cgi-bin/Zope.cgi$1 any URL starting with Zope will match which is not what you want. If you use this rule : http://my.site.com/Zope_any_word _you_like will be converted to : home/httpd/cgi-bin/Zope.cgi_any_word_you_like which fails miserably, because there is not a CGI with that name.
