Is it legitimate to set a 404 Not Found header, then redirect to the correct URL? 回答1: I'd use 301. Moved permanently is appropriate in that it tells the

问题 Using the file .htaccess, I am trying to redirect urls like this: http://www.mysite.com/a-page/?fp=123&sp=456&tp=789 to: http://www.mysite.com/a-page/ so basically redirecting url not caring about params values to the same url without any param.

问题 I have an article on my site that has published in a wrong category. I wanted to change the category, and since the category name is part of the url, I than added a 301 redirection to the updated url. That article had also several likes, but after the 301, it was reset to 0 likes, since to Facebook this is now as a new url with no likes. If I remove the 301 than the likes count is updated again.
