Does it make a difference if your url ends in a trailing slash or not?
Why treat these as different URLs?

I am doing a 301 redirect in my WP application using .htaccess and have mapped some of the URLs which have either been removed from the new domain or the URL structure has been changed. While doing I got a doubt

I have following URL structure in my .htaccess file

RewriteCond %{HTTP_HOST} ^old.com$ [OR]
RewriteCond %{HTTP_HOST} ^www.old.com$
RewriteRule ^tag/waiting$  http://www.new.com/tag/relationships [R=301,L]

while checking this i found that at some places URL is like http://www.new.com/tag/relationships while at others its like http://www.new.com/tag/relationships/, while both refer to the same location but not sure if this will make any difference to SEO and search engines. Please suggest if the way i am doing mapping is correct or do i need to modify it to handle both UR
