Lets say for example that I have a CMS installed on a domain: mycms.com
With Joomla or WordPress on a LAMP environment (Linux, Apache, MySQL, PHP), lets say that it uses CPanel.
And I have a page like for example mycms.com/mycategory which links for different internal post/articles.
mycms.com/mycategory/post-1 mycms.com/mycategory/post-2
Now I have another domain: myotherdomain.com
And I want to setup this domain for that page (mycms.com/mycategory) In a way that every internal page also responds to that, example:
myotherdomain.com/post-1
myotherdomain.com/post-2
Notice, its not a simple redirect using PHP header() or JS, I want that myotherdomain.com to stay visible on browser address.
My question, this is possible? And its possible to do this without a dedicated server with SSH access? How I may do this? Editing my .htaccess?
