I'm working on the project where every page should looks like combination of other sub-pages(left, right, header, footer, center).
Every sub-page is independent and can have links to other pages. Left, right, header and footer pages are static(they are always shown), but center page should changes.
I'd like to get decision where all link change only center page wherever they(links) are stand.
Example: On left sub-page is login page with form. This form has link to registration page. When user press link center sub-page should be rerender to the registration sub-page.
I have no ideas how to do that. I'll be glad to any advices!
