problem trying to redirect a specific url using SSL

I am trying to redirect all https u开发者_JS百科rls to http (except one account/payment):

RewriteCond %{SERVER_PORT} =80
RewriteCond %{REQUEST_URI} account/payment$
RewriteRule (.*)  https://%{SERVER_NAME}%{REQUEST_URI} [R=301,L]

RewriteCond %{SERVER_PORT} =443
RewriteCond %{REQUEST_URI} !account/payment$
RewriteRule (.*)  http://%{SERVER_NAME}%{REQUEST_URI} [R=301,L]

RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule . - [L]

RewriteRule . index.php [L]

Works fine, except when I am going to http://url/account/payment, it's redirect me to http://url/index.php

Thank you

The L flag causes a reinjection of the already rewritten URL into the rewriting process:

Remember, however, that if the RewriteRule generates an internal redirect (which frequently occurs when rewriting in a per-directory context), this will reinject the request and will cause processing to be repeated starting from the first RewriteRule.

To avoid that either of your first two rules are applied on such a reinjected URL, check the request line instead:

RewriteCond %{SERVER_PORT} =80
RewriteCond %{THE_REQUEST} ^GET\ /account/payment[?\ ]
RewriteRule ^account/payment$ https://%{SERVER_NAME}%{REQUEST_URI} [R=301,L]

RewriteCond %{SERVER_PORT} =443
RewriteCond %{THE_REQUEST} !^GET\ /account/payment[?\ ]
RewriteRule !^account/payment$  http://%{SERVER_NAME}%{REQUEST_URI} [R=301,L]

Each time a RewriteRule matches, Apaches does an internal redirect and re-evaluates all the rewrite rules against the new (re-written) path.

So when RewriteRule . index.php matches, REQUEST_URI is changed to index.php and all rewrite rules are evaluated again.

RewriteCond %{REQUEST_URI} !account/payment$ evaluates to true against index.php, and the next rule is evaluated: RewriteRule (.*) http://%{SERVER_NAME}%{REQUEST_URI}, which redirects (externally) to index.php.
