Problem: Site moved from asp to php (Windows Server to Linux). Old Links (Eg. www.addictiveblogs.com/ABC/Home.aspx) are not available on new server.
Solution: .htaccess file can do this for you.
For Example Want to Redirect www.addictiveblogs.com/ABC/Home.aspx page traffic to www.addictiveblogs.com write following code in .htaccess file place that file in ABC folder.
Redirect 301 /ABC/Home.aspx https://www.addictiveblogs.com/
And if Want to redirect traffic of www.addictiveblogs.com/ABC/ link then add following line as well
Redirect 301 /ABC https://www.addictiveblogs.com/
Now Traffic of Both Links will be redirected to your home page.
Redirect 301 /ABC/Home.aspx https://www.addictiveblogs.com/ #/ABC/Home.aspx Old Link Redirect 301 /ABC https://www.addictiveblogs.com/ #/ABC/ Old Folder Link
