When I was on blogger, I used blogger mobile version. Its URL is http://www.mydomain.com/2012/03/posURL.html?m=1. I saw that there are few incoming links (I found 40-50) from that format. Because of some of my blog visitors shared my blog post URL on several web forums. Some of them used mobile URLs. Now those URL's shows 404 not found error, but actually there's a post.
Not only incoming links, Google webmaster tool also shows .html?m=1 links are broken.
Now my blog URL structure is http://www.mydomain.com/2012/03/posURL.html. Are there any way to automatically redirect ?m=1 contain URLs to real posts using wordpress .htaccess file?
