I used to run into the problem of having warning messages pop up when I accessed a page with secure and non-secure information and finally I found something that let me post non-ssl encrypted content on an ssl encrypted page and no warning messages will pop up!
On on of my secure sites, lets say https://www.askapache.com/htaccess/ I wanted to give my visitors the option to post youtube videos and google videos. But then everyone kept seeing the "warning, mixed secure/non-secure content" on a page that had one of these videos.I basically did a str_replace on all posts text for http://video.google.com and http://youtube.com to change them to https://www.example.com/htaccess/ Then I used the following rewrite code:
RewriteEngine On RewriteBase / RewriteRule ^htaccess/googleplayer.swf(.*)$ http://video.google.com/googleplayer.swf$1 [L] RewriteRule ^htaccess/youtube/(.*)$ http://www.youtube.com/$1 [L]and it worked! But one caveat, this wouldn't turn the warning messages off in
IE < version 7, so I added some simple HTML to the head of all my pages that only show up for people using
IE < version 7.
