I want to modify the .htaccess file so that the traffic directed to www.mysite.com/blog is redirected to www.mysite.com/blog/

I tried
RewriteCond %{HTTP_HOST} ^mysite.com/blog$
RewriteRule ^(.*)$ http://www.mysite.com/blog/$ /$1 [r=301,nc]

But nothin seems to work , please help.

I'm having quiet similar problem.

While trying to do blog claim on technorati, it fails. It might be due to the reason that part of the url is being stripped by Technorati. www.domain.com/blog/ -> www.domain.com/blog
Silverstripe redirects www.domain.com/blog -> www.domain.com/blog/?url=/blog

Have anyone found a solution for this problem?

My workaround for the blog redirect problem
NB! Works only with apache server rewritter

Add the 2 following lines into .htaccess file after RewriteEngine On on line 10

...

RewriteCond %{REQUEST_URI} ^/([\w_-]+)([^/]{1})$
RewriteRule (.*) %{REQUEST_URI}/ [R=301,L]

....

For anyone seeing this issue on SilverStripe 3.1, I used the following code in my .htaccess to resolve the issue (as suggested by lestatron)

### SILVERSTRIPE START ###
