secure page redirect

I had a security issue, someone was using webaccess and users passwords
to play havoc - not really sure how they were getting the passwords, as
a result I changed the web server to force secure webaccess connections.
An unwanted side effect of the way I did it is that ALL web pages are
redirected including iManager. I believe there is a better way to do it
than I did but I don't know it. I added these lines to the httpd.conf file:

redirect /index.html https://mail.domain.com/gw/webacc

RewriteEngine On
RewriteCond %{REQUEST_URI} ^\/
RewriteRule ^/(.*) https://%{SERVER_NAME}/gw/webacc [L,R]

Actually I'm doing two things here. I am skipping over the page that has
the language selection and then forcing https. I am willing to modify
the index.html page if necessary to accomplish the change I want, if I
can find out how. I would like to have it redirect only the requests for
the /gw/webacc page and leave the others alone? I do want to force all
webaccess users to use the https connection. Thanks.
