I just implemented a 301 redirect on my entire site to try and get a grip on my canonicalized URLs.
First - if you ever do this, remember to cache your IE browser or you will think a bomb went off in your blog.
Second, I could not login anymore. I changed the conf/_config.php file from:
$baseurl = 'http://myurl.com/blog';
TO
$baseurl = 'http://www.myurl.com/blog';
And this seems to have fixed the password problem. What other issues will I run into with this type of domain wide redirect?
