apache - Force https to http redirect except for Wordpress /wp-admin directory -

our https site indexed on google. need redirected http. we're using following code:

<ifmodule mod_rewrite.c> options +followsymlinks  rewriteengine on  rewritebase / rewritecond %{server_port} ^443$ [or] rewritecond %{https} =on rewriterule ^(.*)$ http://www.example.com/$1 [r=301,l] </ifmodule> 

to redirect https http, , works fine.

however, want exclude of wordpress admin https http redirect, i'd keep wordpress admin working on https, added:

rewritecond %{request_uri} !^wp-admin  

taking .htaccess code to:

<ifmodule mod_rewrite.c> options +followsymlinks  rewriteengine on  rewritebase / rewritecond %{server_port} ^443$ [or] rewritecond %{https} =on rewritecond %{request_uri} !^wp-admin  rewriterule ^(.*)$ http://www.example.com/$1 [r=301,l] </ifmodule> 

unfortunately not work, , trying load /wp-admin on https results in many redirects , wordpress dashboard not load.

www.example.com redirected many times.

would appreciate in excluding /wp-admin https http redirect.

try following, should force http except directory wp-admin:

rewriteengine on  rewritecond %{http:x-forwarded-ssl} !on rewritecond %{request_uri} ^\/(wp-admin) rewriterule (.*) https://%{http_host}/$1 [l,r=301]  rewritecond %{http:x-forwarded-ssl} =on rewritecond %{request_uri} !^\/(wp-admin) rewriterule (.*) http://%{http_host}/$1 [l,r=301] 

if have problems above, can try also:

rewriteengine on rewritebase /  rewritecond %{https} off rewritecond %{request_uri} ^/wp-admin rewriterule ^(.*)$ https://%{http_host}/$1 [r=301,l]  rewritecond %{https} on rewritecond %{request_uri} !^/wp-admin rewriterule ^(.*)$ http://%{http_host}/$1 [r=301,l]
