does this look right?

RewriteCond %{SERVER_PORT}!^443$
RewriteCond $1 ^contact
RewriteRule (.*)$ [secure.example.com...] [R=301,L]

Seems to work...

Simplify:

RewriteCond %{SERVER_PORT} !^443$
RewriteRule ^contact https://secure.example.com/contact/ [R=301,L]

Note that as does your code, this code will redirect anything starting with "contact" using http to "contact/" using https. Note the "starting with" and the added trailing slash. I'm not sure if either of these factors was intentional. Without knowing the local URL-path of your contact form, I can't make a recommendation.

Simplified version works perfectly - thanks Jim.

Note: I'm already handling the trailing slash issue (across all pages) with another rewrite.

Thanks again.

Point being that a request for http://example.com/contact/ will be redirected to [example.com...] by this code.

A proper solution might be:

RewriteCond %{SERVER_PORT} !^443$
RewriteRule ^contact/?$ https://secure.example.com/contact/ [R=301,L]

This will redirect either
http://example.com/contact
-or-
http://example.com/contact/
to
[example.com...]

Thanks Jim - even better.

All of the following requests are properly (301) redirecting:

http://example.com/contact
http://example.com/contact/
http://www.example.com/contact
http://www.example.com/contact/

to:

[secure.example.com...]

Following the code examples in this thread I have tried to go to and from http and https respectively AND to and from the domain without WWW and with WWW. However, I get caught in cycle of redirects. Here is my current .htaccess, where the first block to the secure protocol works fine... but the redirect is submitted to the second block where the 'not this URI' rule apparently is ineffective. Any advice would be much welcome.
