Changing subdomain url to new root url issue (404)

Question

I have a blog on a subdomain technotes.tostaky.biz and I want to move it to a new URL: www.mytechnotes.biz. Of course, I want to redirect technotes.tostaky.biz to www.mytechnotes.biz.

www.mytechnotes.biz has been set-up properly, but I am trying to figure what I should do for the redirect.

Right now, I have two A records (www.technotes and technotes) pointing to the IP address of the root tostaky.biz URL server.I also have a permanent redirect (both www and non-www) from technotes.tostaky.biz to http://www.mytechnotes.biz/.

When I open technotes.tostaky.biz in Chrome, I get a 404 "The requested URL / was not found on this server. That’s all we know."

I don't know what is causing this issue. Should I wait for propagation or do I need to modify my configuration? Should I use CNAMEs instead of A records?

P.S: I forgot to mention that www.technotes.tostaky.biz redirects properly.

Answer 1

Apparently, my (blue) host was not modifying my .htaccess properly. I found the solution here.

I used the following:

RewriteEngine On

RewriteCond %{HTTP_HOST}%{REQUEST_URI} ^technotes.tostaky.biz/$ [NC,OR]
RewriteCond %{HTTP_HOST}%{REQUEST_URI} ^www.technotes.tostaky.biz/$ [NC]
RewriteRule ^(.*)$ http://www.mytechnotes.biz/$1 [r=301,nc]

instead of:

RewriteEngine on

RewriteCond %{HTTP_HOST} ^technotes\.tostaky\.biz$ [OR]
RewriteCond %{HTTP_HOST} ^www\.technotes\.tostaky\.biz$
RewriteRule ^/?$ "http\:\/\/www\.mytechnotes\.biz\/" [R=301,L]
