htaccess force ssl except for rss feeds

Question

My site currently forces SSL everywhere. This is the way that I want except that it is causing issues with my RSS driven newsletter and feedburner. Due to this I need to make exceptions for my feeds.

Can someone help with the proper htaccess rules to pull this off?

My feeds are

/feed
/shop/feed
/forum/discussions/feed.rss

Here is my condition for forcing SSL. This works except that all RSS feeds are forced to.

# Force SSL
RewriteCond %{SERVER_PORT} 80
RewriteCond %{REQUEST_URI} !^/forum [NC]
RewriteRule ^/?(.*)$ https://photoboothowners.com/$1 [R=301,QSA,L,NE]

I tried the following but it did not seem to work correctly.

# Force SSL
RewriteCond %{SERVER_PORT} 80
RewriteCond %{REQUEST_URI} !^/forum [OR]
RewriteCond %{REQUEST_URI} !^/feed [OR]
RewriteCond %{REQUEST_URI} !^/shop/forum [NC]
RewriteRule ^/?(.*)$ https://photoboothowners.com/$1 [R=301,QSA,L,NE]

Your help is greatly appreciated!

Update: This is my current .htaccess file in the root of my server. This is currently redirecting http://photoboothowners.com/feed to https://photoboothowners.com (notice it is dropping the feed directory).

RewriteEngine on

Answer 1

Your rules are using OR so they read as:

if server port is 80 and the request is not forum OR it is not feed OR it is not shop/forum

That's going to match everything. Get rid of both of the [OR] so that the match reads:

if server port is 80 and the request is not forum AND it is not feed AND it is not shop/forum

EDIT:

Per your updated question, the following line is missing a slash:

RewriteCond %{REQUEST_URI} !feed [NC]

should be

RewriteCond %{REQUEST_URI} !/feed [NC]
